The impact of intensive and biologized cultivation technologies on soil properties and barley yield

The paper presents the results of a study of the comparative effectiveness of intensive and biologized technologies of barley cultivation. Intensive technology included the use of calculated doses of mineral fertilizers for programmable yields, pesticides, and chemical stubble destructors. In biologized technology, all chemicals have been replaced with biological ones. The soil of the experimental field is leached heavy loamy chernozem with an average humus content, high P 2 O 5 and elevated K 2 O. A significant increase in the activity of the soil microbiota has been established when using biologized crop cultivation technology. In terms of the content of nutrients, it is relatively inferior to intensive. It is proved that in favorable conditions of vegetation (precipitation, air temperature) and an increased content of nutrients in the arable layer, when using a biologized cultivation technology, it is possible to form a yield of barley that is practically not inferior to intensive.
