Quote by V.V. Dokuchaev about the importance of chernozem for Russia.

Laboratory for the analysis of the quality of the earth.

All-Union Institute of Organic Fertilizers and Peat.

Experience with the addition of humus to ordinary Non-Chernozem soil.

The seeds were planted in a vessel with humus and without it.

The sprout on humus is larger than on earth without humus.

Organic matter creates the soil.

Earthworms.

They recycle the soil, making it lumpy and porous.

Organic fertilizers work similarly.

Such soil absorbs moisture well and delivers it to the roots of plants in a timely manner.

Experience.

Cars carry hay from the fields.

Straw bedding has always been used in the care of animals, despite the difficulties with cleaning.

As manure accumulates, it is removed to concrete platforms or to the edge of the field.

The quality of manure depends on the storage method.

Rotted manure is considered the best.

The stack of manure should be of such a size that in winter the manure does not freeze and does not lose its useful properties.

From autumn to spring, farms harvest peat.

Litter peat absorbs moisture, absorbs harmful gases, improves the microclimate in the cowshed.

However, the main thing is a natural storehouse of organic substances.

Peat is scattered on walking grounds.

When mixed with manure in peat, biological processes are activated, the richest microflora comes to life.

The field and the farm are an inseparable whole, two workshops of waste-free production.

Cows graze on the paddock.

Conveyor for the removal of unpadded manure.

Composting such manure with peat makes it possible to include additional organic resources in the biological cycle.

The bulldozer loads the compost into a special machine for applying it to the soil.

Creating compost on a special site.

All components of the future compost are applied layer by layer to the peat pillow.

Bespodstilochny or liquid manure and mineral fertilizers are thoroughly mixed.

To reduce the acidity, lime or phosphorous flour is added.

Aeration and humidification conditions are checked in the stack, under which biothermal processes are actively taking place.

The temperature should rise to 50-60 degrees, at which weed seeds die and helminth eggs die.

On large farms, the method of pushing it by the animals themselves is used to remove manure, then by gravity into the manure collection.

In pigsties, sloping floors are used, ending with a slit hole for waste runoff.

Manure processing workshops.

Manure is divided into fractions.

The solid fraction goes to drying and is stored in the burts, and the liquid is accumulated in the settling tanks.

Waste is not discharged into the environment.

The development of poultry farming in the country has led to a sharp increase in the amount of bird droppings in organic fertilizers.

In its pure form, bird droppings are not recommended.

It is composted with peat and other additives.

Mixing plant in the Vladimir region.

This unit dispenses and mixes three components: manure, peat and phosphorous flour.

Compost production equipment.

Organic norms are calculated based on the fertility of the soil, the balance of humus in it and the planned harvest.

The amount of fertilizers for different crops.

Machines scatter organic fertilizers across the field.

Immediately after application, it is necessary to make a smell.

A popular saying is that a field remembers manure for three years.

Manure provides not only root, but also aerial nutrition of plants.

Decomposing, manure releases carbon dioxide into the ground layer of air, photosynthesis proceeds more fully.

The liquid fraction is applied to crops that need a lot of nitrogen.

For some crops, it is necessary to reduce the rates of compost application.

Harvesting.

In farms where everything is safe with feed, straw is not removed, but crushed and left as fertilizer.
