THE ROLE OF MIERAL FERTILIZERS IN ERODED SOILS AND THEIR IMPACT ON PLANTS

Abstract

The research was carried out to study the importance of mineral fertilizers in reducing fruit loss taking into account eroded soils. The method of applying mineral fertilizers was used when they were applied together with ammophos and manure. Experimental work was carried out by setting up vegetation experiments. Growth processes and fruiting of cotton are enhanced when ammophos with nitrification inhibitors and manure is added to the soil; Cotton productivity increases by 2.5 -3.5 c/ha. The analysis results show that the combined application of nitrification inhibitors N-serve, ATG and manure with ammophos helps to increase the efficiency of ammophos nitrogen per year of action and aftereffect on cotton up to 32.2-36.4% in micro- and macrolysimetric and 38.0 -48.0% - in field experiments. The combined main application of ammophos to the soil with nitrification inhibitors ATG helps to reduce the loss of not only ammophos nitrogen, but also nitrogen from soil sources. All this together led to a decrease in the number of falling fruit elements and, accordingly, an increase in cotton yield by 12-15% compared to the control.
