Abstract
The results of studies on nutrient content (hydrolyzing compounds of nitrogen, mobile compounds of phosphorus, exchangeable potassium) at the used of fertilizers and tillage on the soil chernozem typical low-humus were presented. Agricultural use of soil without the use of fertilizers leads to its partial degradation was established. The application of different fertilizer systems positively affects the improvement of the basic elements of mineral nutrition in typical chernozem, while the nitrogen content exceeds the control variant at the organic system on the 45%, for organo-mineral – 71%, mobile phosphorus at the organic system on the 22%, organo-mineral – 69%, mineral – 62%, exchangeable potassium at the organic system on the 16%, organo-mineral and mineral – 53%, respectively. The variant of dump-bottomless tillage of soil positively influenced the improvement of the nutritional regime of typical chernozem.
