Do-it-yourself compost pit: manufacturing options with photos. Making compost pits the right way. Three variants of execution Make a compost pit in the country house

Organic fertilizers are not all equally available. It is possible to obtain manure in an amount sufficient to fertilize the site only if it is possible to keep livestock. Otherwise, manure remains only to buy. The situation is much easier with compost. Having built a compost pit on the site, you can organize the production of an excellent, highly environmentally friendly first-class fertilizer. In addition, properly prepared compost eliminates the ingress of helminth eggs into it, which are often found in manure.

What do you need for a compost pit

Compost is a product obtained from the natural processing of plants. For a small standard area, a pit with a volume of one and a half is quite suitable. square meters. A set of tools necessary for preparing the pit is available on the site of every self-respecting gardener - this is a bayonet shovel, covering material (for example, old film) and a wood saw.

To strengthen the edges of a dug hole, boards, pieces of slate are suitable, you can use a brick. The compost should be placed in a secluded area of ​​​​the site and in such a way that the wind does not bring the aromas of rotting mass to you. You should not arrange a structure near fruit trees - they can die from such a neighborhood.

How to make a compost pit

Make markings on the ground for a future compost pit and remove the sod around the entire perimeter for half a shovel. It is not necessary to dig deep deep - this will lead to a constant accumulation of rainwater, which will slow down the processes of decay. Fix wooden pegs along the edges of the removed turf. They are hammered in deep, after which boards are nailed to them. It will turn out something like a sandbox, but it must be filled not with sand, but with plant debris.

For compost, you can use cut grass, leaves, tops, rotten root crops. Raw fruits, cereals, twigs, sawdust, and even small pieces of paper will do. Bones, potato leaves, animal excrement and non-organic debris should not be thrown into the compost.

When filling, the main thing is to dump plant residues in as much as possible, but they should not be rammed, because silage will turn out. At correct styling the compost will rise slightly above the edges of the boards. If there are no extra boards on the site, you can simply form a pile and wrap it around the edges with pieces of slate or rubber mats. In dry weather, the future compost must be watered.

In conclusion, the pit must be covered with a film or other covering material - this will help create a greenhouse effect. The process of natural processing of the contents of the compost pit will take one and a half to two years.

For any gardener, compost is the best and most affordable fertilizer, because it can be prepared on your own using organic waste.

There are many options for preparing a compost heap, I must say that the fantasy of our summer residents knows no bounds. One of my good friends once said that she does not throw anything away from the site, everything goes into action and feeds the earth.

Passing by the plots, you can see a wide variety of examples of closing a compost heap or pit, the most different variants starting from wooden planks, ending with furniture parts, fine mesh netting, slate and metal sheets.

In order to competently prepare high-quality compost, it is not enough to dump everything that comes to hand in one place, you need to know some rules, which we will get acquainted with in this article. Experienced gardeners shared their skills in preparing compost, and this material was written based on their experience.

We know that during the summer season, a large amount of waste from organic waste accumulates, which include food residues, weeds and mowed grass, which are constantly removed from beds and lawns.

All this waste must be disposed of in one specific place, in a compost heap, which in two to three years will give you a high-quality product in the form of an excellent fertilizer.

Along the way, this will help get rid of unnecessary plant materials, your site will be clean and tidy, the waste will not have to be taken far beyond the garden.

The decomposition of plant waste in a natural way takes about 20 months, but if the process is artificially accelerated, it is possible to achieve a result in three months.

What you need to know about compost

Nutrient fertilizer is able to reach the condition if it is warm and humid. To prepare the place of its "production", to provide a bunch of all the necessary requirements - the main task of the gardener. A sufficient amount of oxygen will allow you to get not a fetid heap of waste, but a real universal fertilizer.

• It is necessary to make sure that the main part of the pile is located above ground level. So the contents will be perfectly warmed up, provided with air. It will be convenient to water and loosen. The depth of the pit should be no more than half a meter, and the surface part up to a meter. By width ideal parameters become: 1.5X2 m.
• If there is a source from which drinking water is used: a well, a well, a spring, a territorial gap of at least 20 m should be taken into account. For greater certainty, if the site slopes, make the pit lower.
• Close up a pile of waste should be away from the house or recreation area, as bad smell will spoil the air and mood not only for the owners of the site, but also for the neighbors. This issue must be approached responsibly, and choose a place that would suit everyone.
• To prevent the pile from drying out, do not place it in a sunny area. Well, if it were in partial shade, then the moisture necessary for the decay process would not evaporate quickly.
• In no case should the pit be close to fruit-bearing trees, this is fraught with their death.

Important! You should not make the bottom of the pit, from any material: slate, iron, film. The compost heap should have an earthen bottom, so moisture from the earth will rise up and the contents will not dry out. For walls, any of the listed materials is suitable.

What can be added to the compost heap

Good, high-quality compost will be obtained by laying the following components in a pile:

• fallen leaves, needles, plant roots and small branches and stems;
• cut grass and weeds;
• manure and litter, the age of which is more than two years;
• peeling vegetables, fruits, berries, peels of any fruits;
• leftover food, coffee and tea;
• hay, straw, sawdust and other small wood waste;
• wood ash;
• paper waste, cardboard.

Important! Grass that is laid in in large numbers, it is best to sprinkle with soil.

What is contraindicated for a compost pit:

• any objects of inorganic origin made of plastic, polyethylene, metal and synthetics;
• bones;
• stems from potatoes and tomatoes, due to late blight infection;
• large branches and mature seeds of weeds.

Compost heap options

There are a large number of options, and each gardener chooses the most acceptable and effective for himself.

A simple pile of layers of waste

First, decide on a place, and start laying organic matter in layers, alternating it with manure and food waste. After the hill grows a meter, make indentations in it, pour a special liquid into them for the fastest maturation of the compost.

Such preparations are sold in gardening centers and stores, they contain bacteria that, when they enter the organic environment, begin to work and process it.

If you do not forget to loosen the waste, then the compost will ripen in three months. That is, laying a pile in the spring, by the end of the summer you will be with compost.

For those who do not want to make a stationary facility for the production of compost, this is an ideal option. It is desirable that there are several such places, then you can achieve constant replenishment of your site with fertilizer.

A hole dug in the ground

In this case, too, everything is simple. A hole is dug in the soil, the size of which depends on your appetites. Branches, the remains of bark, straw, hay are placed at the bottom, then a layer is laid, consisting of the remains of food and plants. Next is a layer of manure, and a repetition of the vegetable layer.

In such a structure, the temperature will not reach high levels, so the pit is covered with a film. This option is suitable for those who are not in a hurry, as the compost will not ripen soon. But there are also advantages - a simple device and a small area.

Box of bars, slate, boards or metal

This method is used by many gardeners, and is 100% justified. However, the preparation of the box will require small material costs and some effort to equip it.

• First of all, at the site of the future compost pit, the soil is removed, about 50 cm.
• Along the entire perimeter of the recess, bars or pegs should be driven in.
• Next, a fence is made for which any material is suitable: shields, bars, boards, mesh, polycarbonate, metal sheets, slate of any shape. The main thing is that the material does not bend or break under the weight of the waste.
• The height above the soil surface should correspond to one meter. This height will allow you to easily loosen and mix the contents.
• From above, the structure is closed with a film or plywood sheet.

Wooden box with a door

For convenience, you can build a door in the box, at a distance of 50 cm from the ground. This option allows you to choose the finished compost from below, while upper layer settles.

Ease of use, as well as the ability to take required amount ready-made fertilizer - these are the main advantages of boxes with sliding or lifting doors.

Pit made of concrete or brick

This design is durable, it will require significant costs and labor. A plot for a compost heap is marked out taking into account the impossibility of transferring to another place.

• The soil is selected to a depth of 70-80 cm;
• It is necessary to make formwork around the entire perimeter of the pit;
• After the concrete is mixed, it is poured into the formwork, 10-12 cm thick;
• Wooden formwork is removed as the concrete dries;
• The concrete pit is filled with waste and covered with a film or wooden shield.

Important! It is very important to have two or more sections in each of the proposed facilities. One will serve as a compartment for fresh waste, and the second is intended for last year's compost. Thus, every year you will have a nutrient substrate for plants and soil.

Other Compost Heap Options

The most advanced gardeners, who have the means to significantly facilitate their work, purchase ready-made biocontainers for the production of compost. They use preparations with an accelerated action for the processing of organic matter based on special bacteria: Baikal EM-1, Compostin, Embionik.

Many gardeners breed Californian worms, these creatures are extremely efficient and each works like a mini. processing plant for the production of compost.

Remember, full-fledged compost requires air, water, heat and clean organic matter. Only with these components you will receive high-quality and free fertilizer.

5 minutes to read

Compost is a faithful assistant to the gardener in caring for plants and improving soil properties. It is used both to improve the quality of the soil, and as a fertilizer, and for mulching. Do-it-yourself compost at your dacha does not require special efforts and high material costs. To do this, you just need to select and equip appropriate place where you can compost herbs and other organic waste. Consider how to make a compost heap and use it correctly.

Rules for the location of the compost pit

Before you make a compost pit, you need to pick up correct plot in the country, where your organic fertilizer will ripen. To do this, it is important to adhere to the following rules:

• so that composting waste does not fall into drinking water, a bunch is arranged no closer than 30 meters from sources - wells, wells, streams and other reservoirs;
• if on personal plot there is a slope, the pit is located below the level of water sources;

• the pile is arranged away from residential buildings, while the prevailing winds are taken into account so that the smell of composted grass does not cause inconvenience to either you or your neighbors in the country;
• it is undesirable to leave fertilizer under the open sun - in such conditions, the processes of decomposition of organic substances slow down or stop altogether, so it is better to place the pit in the shade.

Important! It is necessary to provide free access to the pit so that nothing prevents the laying of waste and the removal of ready-made compost on a wheelbarrow.

Compost pit device

Universal sizes for a compost heap are:

• width - 1.5 m;
• length - 2 m;
• height above ground level - 1.5 m;
• depth - 0.5 m.

The design is made both open and closed.

1. For the most common open-type compost heap in the country, they dig a hole of small depth. The walls are covered with slate. The bottom of the pit does not need to be isolated, through it there should be free access to the compost for worms and microorganisms that promote fermentation. Leaves, grasses and other organic waste are placed at the bottom. To prevent the spread of smell, cover with a tarp.

open design

2. Closed pit suggests more complex structure. Along the perimeter of the pit, a wooden or concrete frame. The tree is pre-treated with compounds that will prevent the material from rotting. The frame is sheathed with timber, boards or lined with bricks. It is more convenient to make a structure with a pitched lid, which is hinged to one of the sides.

Closed variant

Filling the compost pit

The compost pit can be filled gradually, as organic residues accumulate. But if your goal is to fertilize the site as quickly as possible, then it is better to fill it right away. Not only herbs are suitable for this, but also other waste that often appears in the country.
The following scheme for laying compost is optimal:

1. the lowest layer is formed from sawn branches or large sawdust, roots and bark of trees, there may also be fallen leaves and needles;
2. the next layer is filled with plant residues - raw vegetables and berries unsuitable for food, grass, straw, you can also put crushed paper and cardboard;
3. the third layer is rotted herbivore manure or bird droppings. You can add ammonium nitrate.

Reference. When filling the compost pit, take into account the composition of the soil of your site. If the soil is acidic, wood ash is added there.

The second and third layers are alternated until the hole is completely filled.

Schematic diagram of a compost heap

As the residues decompose, all contents are periodically shoveled.
Not all plant residues are allowed to be composted.

1. It is unacceptable that weed grass with seeds or vegetables infected with late blight and other fungal diseases get there. Together with the compost, they will move to the site and continue their detrimental effect among healthy crops.
2. Do not throw bones and meat waste, insects, polyethylene and other synthetics, as well as plants treated with chemicals into the compost.

Watering the compost heap

Compost fertilizer needs to be watered. The level of humidity must be sufficient for the effective functioning of microorganisms that contribute to the formation of useful organic elements.
Watering is carried out warm water. After moistening, the pile is covered with a film to form a greenhouse effect. For the fastest decomposition, a glass of sugar diluted in warm water with yeast is added to the fertilizer. This will increase the rate of compost maturation by several times.

Component balance

The ripening process is accompanied by the release of heat. This is easy to check when the owner is shoveling the compost. In the center the temperature reaches +60…+70°С. If the contents are cold to the touch, add more nitrogenous components - grain, bread, rotting fruits and vegetables, rotted manure.

Another compost heap arrangement

Ideally, compost should be prepared from equal amounts of nitrogenous and carbonaceous materials. The latter contribute to greater breathability. These include: straw, grass, sawdust, paper, shredded cardboard.

The yield depends on the quality of the soil. This is known to all gardeners. But garden land is not always rich useful substances. Therefore, it has to be fertilized additionally. You can use ready-made formulations or organic fertilizers. But the best option will be the construction of a compost pit. Thanks to her, there will be where to put the cut grass and food waste. And fertilizer from it will turn out no worse than store compost. The point is small - to choose a convenient design and appreciate it.

Choosing a place for a compost pit

Before proceeding with the construction, it is necessary to determine the place for the compost heap. This will help to follow some rules:

1. 1. The compost pit must be located at a distance of at least 30 meters from wells, wells and other bodies of water.
2. 2. Observe the distance from residential buildings. The unpleasant smell from the compost should not cause inconvenience to either your neighbors in the country or you.
3. 3. If the site has a slope, then it is better to place the pit at the lower level.
4. 4. In the sun, waste decomposes more slowly. It is better to choose a place in the shade.

There must be an accessible passage to the pit in order to pass or drive a garden wheelbarrow.

General device requirements

The compost bin must function properly. Microorganisms and bacteria that digest vegetable waste, should actively multiply in it. To do this, create comfortable conditions. Just digging a hole or making a box is not enough. The following factors affect the normal life of microorganisms:

1. 1. Free access to oxygen. Thanks to him, the waste will not rot, emitting an unpleasant odor, but decompose under the influence of bacteria and earthworms.
2. 2. Sufficiently high humidity.
3. 3. A certain temperature is + 60-70 degrees.

You can put in the compost pit: the remains of raw or spoiled vegetables, fruits, berries, as well as various grains, grass, hay, ash, foliage, needles, bark, branches, plant roots, sawdust, shredded paper, herbivore manure.

It is impossible in any case: bones, potato and tomato tops, greens treated with pesticides, weed seeds, synthetic waste, tops of infected plants.

If all conditions are met, then the compost will turn out to be correct and of high quality..

We can distinguish the main requirements for the construction of the pit:

• for free access of oxygen, the compost container must be above the soil level;
• if the pit is located in the soil, then it should not be buried at a distance of more than half a meter;
• it is better to make one of the walls of the container removable or in the form of a door, so that it is convenient to get the finished compost;
• the size of the box should be chosen based on the amount of fertilizer required. Optimal size- 1 by 2 meters. If the plot is large and a lot of compost is required, then it is better to make several containers with dimensions of 80 by 100 cm;
• The height of the container should be such that it is convenient for a person to loosen the contents. The optimal height is not more than 1 meter;
• don't cover the bottom. It must be earthen for the free movement of worms and to maintain moisture.

Based on the basic requirements, you can start looking for a suitable compost pit design.

Manufacturing options

There are several ways to make a compost pit with your own hands. They differ in size, design and materials.

buried compost pit

One of the quickest and easiest ways to make a compost pit is to dig a hole in the ground. But this option is more suitable as a temporary one, since the quality of the raw materials will be low.

Due to poor oxygen access, the waste in such compost will not decompose, but rot. To obtain normal humus, they often need to be loosened and mixed. Otherwise, the smell of rotting waste attracts many flies.

The recess for the pit should be 40-60 cm. Any size of the sides can be made, but up to 70 cm. large sizes the soil will begin to crumble.

If you need a large pit, then its walls need to be strengthened. For this, boards or slate are suitable.

surface construction

An equally simple, fast and low-cost way is to stack plant waste in the form of a small stack. True, there are significant shortcomings here. For example, loosening it will be very inconvenient. And getting ready-made humus from below is also problematic.

If there is no other option, then before laying out the waste, you need to lay a layer of branches on the soil for better air circulation. It is desirable to choose a place in the shade. Top stack cover opaque material, for example, roofing material. Surface compost will be ready in 1.5-2 years.

With a large amount of waste, several piles can be organized. And while one is ripening, put the waste in the second. You can arrange a compost heap in a bed that is resting. And next year, plant zucchini or cucumbers on it.

From the boards

A common option for making compost is a box. It can consist of 1, 2 or 3 sections. Experienced gardeners recommend a box with three sections using Finnish technology. This is convenient, because ready-made compost is stored in one compartment, it matures in the second, and waste is placed in the third.

It can also be made stationary or mobile. For a mobile version, it is enough to make a bottom with small slits and attach the wheels. The height of the box should be no more than 1 meter in height. For sections, the optimal width of the sides is 0.5-0.7 meters. With such dimensions, it is convenient to lay and loosen waste, as well as to get ready-made compost. Boards for the construction of the composter should be treated with a protective compound that will protect them from moisture and insects.

In order to make a box into three sections, you need:

• dig 8 processed bars into the ground;
• at a distance of 0.5-1 cm, attach partition boards;
• the bottom can be made of boards or put large branches.

If desired, each compartment can be supplemented with doors above. For the construction of walls, it will be nice to use pallets.

compost bin

This option can be made even by inexperienced gardeners. Special tools and special efforts are not required to make a basket. Necessary materials:

• welded metal mesh with cells measuring 50x50 or 40x40 mm, 3 m long, 70 to 100 cm wide (this is the future height of the basket);
• black geotextile or polyethylene film 3.5 meters long and 75-105 cm wide;
• large stationery clips - 10 pcs.;
• knitting wire or plastic clamps for fastening a metal mesh.

From tools, prepare metal and ordinary scissors, tape measure and pliers.

Expand the mesh, straighten it and measure the length of 3 meters. Roll up into a cylinder and connect the ends with an overlap of about 20 cm. Fasten the mesh from both edges with wire or clamps.

Measure and cut required size films or geotextiles. Roll it up and place it inside the basket. It is good to distribute the material on the walls. Turn the top edge outward and fasten stationery clips. The compost bin is ready. It can be placed in an old basin, and it will become mobile.

When filling the basket with the first layer, you need to put branches. Pour plant and food waste with a small amount of soil. Then spill the contents with water, cover with a film on top and leave to ripen.

from slate

A fairly affordable and easy way to make a slate compost pit. Especially if there are unnecessary sheets roofing material. And even if they are damaged, it will benefit the compost. Air will flow through the cracks, which will favorably affect the humus. And the slate will act as a limiter for waste so that it does not spread over a large area.

To build a box, you need to do the following:

1. 1. outline a drawing of the future composter. If you plan to make a box into two sections, then their size should be 0.8 by 1 meter or 1 by 1 meter. The height of the three walls is optimal - 70-100 cm, and the front one - 30-50 cm for more convenient laying of waste and extracting the contents.
2. 2. Choose a place for the location of the pit and remove the top layer of soil by 20 cm. So earthworms and moisture will enter the compost freely.
3. 3. To fix the slate, install wooden or metal posts around the perimeter.
4. 4. Place the slate sheets in such a way that there is a gap of 20-25 cm between the bottom edge and the soil. This will allow a better supply of oxygen.

Concrete structure

A more expensive and time-consuming construction is made of concrete. If it is built below ground level, it will be inconvenient to use.

The construction of a concrete compost pit consists of the following steps:

1. 1. Mark the place where the structure will be placed. The size of the sides can be from 1 meter or more if a lot of humus is required.
2. 2. Dig a pit 0.5 m deep.
3. 3. Install plywood or board formwork for the entire depth of the pit.
4. 4. It is desirable to lay a reinforcing mesh between the soil and the tree.
5. 5. Mix a mortar of cement (1 part), sand (2 parts) and gravel (4 parts).
6. 6. Pour the resulting solution into the prepared formwork and pierce it many times to the bottom with reinforcement or a thin pipe. This will avoid air voids. Leave to dry for 1-1.5 weeks.
7. 7. Build the walls of the compost pit with bricks above the ground. You don't need to make it solid. It should have holes for air circulation. The height of one of the walls is 0.5 meters for the convenience of stacking waste and getting ready-made fertilizer. Three others are 1-1.5 m in size.

In such a design, plant waste will be processed for at least two years. To speed up the process, you can use special solutions and regularly spill the contents.

You can also make a composter for one or two compartments. One will store the ripened fertilizer, and the second will be constantly replenished. The bottom must be left earthen for the free movement of worms.

Decorating the compost heap

Whatever structure you build for compost is unlikely to be attractive in appearance. Therefore, it is advisable to think about how to decorate it. This is especially true for small areas where all the buildings are in plain sight. You can hide the composter using the following tricks:

• put next to him tall plants or a hedge;
• plant climbing plants around the perimeter;
• decorate artificial materials, for example, a masking grid;
• build a decorative fence behind which the pile will be completely hidden.

Thus, the compost pit will not only be a source of environmentally friendly and useful fertilizers. She will decorate the garden.

If the site has poor soil, then a container is built to create humus, which is an important part of any garden plot. The use of top dressing in the form of compost allows you to grow environmentally friendly vegetable and vegetable crops. Recommendations from experienced gardeners will help you understand how a compost pit is created with your own hands, manufacturing options, photos and installation features of which can be considered in detail below.

Tanks can contain several compartments, which increases their performance

A compost pit is easily created with your own hands. In this case, manufacturing options can be seen in the photo. Simple products can be made from pallets, which are taken after the sale building materials and purchased for a small amount.

It is important to choose the right location. It should be far from home. It should be a well-ventilated area. This will prevent bad odors. Containers from improvised materials are distinguished by high availability. The finished design allows you to dispose of weeds from the site.

Useful information! The vegetation is compacted over time and, under the influence of bacteria and moisture, is converted into an excellent organic fertilizer. Perfectly is suitable for processing of different cultures in a kitchen garden or a garden.

What is the purpose of the pit?

An excellent method of recycling various garbage is a do-it-yourself compost pit. Manufacturing options, photos and drawings can be found in sufficient quantities on the Internet. This facility allows you to get high-quality fertilizers in as soon as possible. In this case, cut grass, leaves and manure are used.

How to make a compost pit with your own hands: video and installation requirements

Many gardeners and summer residents are interested in the question: how to make compost pits correctly. Tanks are constructed from three parts. In this case, 8 columns are installed, which are treated with a protective solution. It can be fuel oil, engine oil and tar.

For one of the parties it is recommended to use a fence cloth. Partitions are made of boards in which holes for ventilation should be left. Doors are installed on all compartments. At the end of the work, you need to install handles and latches.

An important point is the installation of ventilation holes. Also, the container must be closed during precipitation with a special lid. For this, ordinary polyethylene film can be used.

You can make a product from pallets. To do this, they need to be disassembled. With the help of the board they are divided into separate blanks. All boards are fastened vertically. In this case, the front board is attached with an adhesive solution.

In order for the pallet product to remain stable, it is necessary to trim the planks at the bottom using a level.Compost pit according to Finnish technology differs from standard pits. She has several distinctive features. Filling must begin from the first compartment. When extracting humus, the container is filled from the adjacent compartment.

All processed material must be stirred periodically. Also, the container should maintain an optimal level of humidity.

Installation of such a structure consists of the following steps:

• wood planks are treated with a special compound;

• side walls are being assembled;
• the walls are sheathed with boards, two walls are made with gaps and two of tightly standing boards;

• boards for the back side are attached;

• the bottom is made;
• cover is mounted;

• lower doors are installed.

Useful information! The wood from which the pit is made must be impregnated with a special solution. This will prevent damage from high humidity, harmful insects and decay processes.

DIY compost pit: manufacturing options, photos and nuances

There are many ways to make compost pits in the country. It is worth choosing a type of structure that meets the requirements of a particular area.

The most famous methods are used:

• building a hole in a certain place. The pit should look like a well, but be smaller. At the same time, the walls of the pit are additionally strengthened and sheathed, but only at a height of 20-25 cm from the bottom, so that microorganisms easily penetrate inside;

• container is mounted on garden plot. This allows you to get the compost mixture at any time. Formwork is at the base of the pit. In this case, a plastic tank or a box of boards is used; It is important to install ventilation holes;

• most in a simple way considered the creation of a compost heap. This creates a substrate of sand, dried grass and gravel. Waste is laid on top, which must be recycled.

There are many options for creating such a structure. They differ not only in materials, but also in the properties of the tank and dimensions.

Useful information! Before laying plant materials in the structure, you need to carefully loosen the bottom and install a vent. After rains, the pit can be covered with polyethylene to speed up the work of microorganisms.

How is a compost pit made from slate in a country house?

The advice of the masters will help you decide how to make a compost pit in the country from slate in order to get a reliable and durable construction.

Slate canvases will be an excellent basis for the walls of the box. The construction is carried out in several stages:

• suitable dimensions are determined;

• after choosing a site for the location of the structure, you need to make a small recess;
• supports made of pipes or boards are mounted in all corners;

• with the help of slate sheets, a pit is mounted;
• a partition is installed in the box, which divides the space into two parts.
