The beginning of the XXI century was marked by a significant depletion of the zoological fauna of Ukrainian black earth, which are used for growing crops.

In particular, there have been fewer nods and earthworms. On lands where pesticides, ammonia water, phosphate slag and ammonia are used, they generally ceased to exist, according to research results.

At the same time, meadows and pastures remain a haven for earthworms, where in 1 ha of soil there are from 250 thousand to 1 million individuals with a live weight of 0.5-1 tons. As a result of their vital activity, the water permeability of the soil increases - up to 25 mm / h., The ability to water retention - by 17%. To acceptable values, the pH also increases.

Earthworms well structure the soil and additionally enrich it with beneficial microflora due to the absorption of soil particles and the digestion of organic matter in it. Scientists have proved that earthworms in the amount of 4-6 individuals are able to absorb up to 90 t / ha of land in the warm season.

Coprolites, or secretions that have passed through the digestive tract of worms, have a high concentration of nutrients in high concentrations, which are easily absorbed by plants. So, they are twice as rich as magnesium, 5 times as nitrogen and 7 times as mobile phosphorus and soluble potassium.

Farmer Vladimir Moklyak has been studying earthworms and their effect on soil for 8 years. He is going to present the most interesting results of his stationary experiment at the conference “Effective Agriculture. Know-Till - the technology of the future ”, which will be held May 23-24 in Mirgorod.
