SOIL STRUCTURE AND CHANGES IN THEIR PHYSICAL PROPERTIES UNDER THE INFLUENCE OF EROSION PROCESSES
Keywords:
corn, fertilizer, phosphorus, orthophosphate, culture, yield, productivity, polyphosphate.Abstract
As a result of the study, the different effects of different forms and rates of phosphorus fertilizers based on Zarafshan phosphorites on the assimilation surface of leaves, an increase in leaf area in one plant and hectare were determined when using ammonium polyphosphate and liquid complex fertilizer ZHKU grade 10:34:0. In a low background of soil fertility, the assimilation surface of leaves in the ammonium polyphosphate variant was higher by 20.1% compared to the control, in an average background of soil fertility - by 11.3%, net photosynthetic productivity - by 15.5%, when ammonium polyphosphate was added and liquid complex fertilizer.
