Abstract

The article presents the results of the study of the effect of new types of nitrogen fertilizers - nitrate with the addition of bentonite, calcium and lime on the conversion in irrigated typical serozem for the main phases of cotton development and its growth and development indices. It is established that the application of the fertilizers under study contributes to a certain increase in the soil content of total humus and nitrogen, as well as phosphorus and potassium, with a noticeable increase in mineral nitrogen, mobile phosphorus and potassium in comparison with the control variant where standard ammonium nitrate was used. These positive aspects with regard to improving the nutrient regime of the soil promoted better growth, development of cotton in variants where modified types of ammonium nitrate were used.
