Вміст азоту, фосфору і калію у чоноземах типових під різними фітоценозами

Abstract

The paper presents a comparison of the content of alkaline hydrolyzable nitrogen, mobile phosphorus, and exchangeable potassium in typical chernozems of the southeastern forest-steppe of Ukraine, which are under different agricultural load. It was found that among the presented of typical chernozems different uses, the highest nutrient content, and therefore fertility, is in the chernozem of a typical fallow land. The indicators of typical chernozem under the forest belt are close to those of fallow typical chernozem, and the indicators of arable soils correspond to the lowest level among the studied variants, which distinguishes arable (agrogenic) soils from chernozems under the forest belt and grass vegetation.
