The article presents the 3-year results of studying the effect of the long-term use of phosphate fertilizers on the content and accumulation of various forms of phosphates in brown soils, and the influence of the levels of available phosphates on crop yields in crop rotation. We identified the levels of phosphate that can be used to optimize the nutrient status of dark-brown and light-brown soils of Kazakhstan with monitoring and regulating plants nutrition of studied crops that are cultivated in crop rotation.
