Abstract: The history and changes in some agrochemical properties of the soil as well as the product quality and yield indicators in the transition from the experience of "Stationary Shebantsevo № 5" to the modified experience of "Stationary Shebantsevo Modified № 5" are considered. Sampling was carried out for soil - in 1992, 2004, 2011, 2014, 2016, and 2017, for plant products - in 2013, 2016, and 2017. To realize the purpose of the study, it was necessary to study the interrelationships between the agrochemical properties of the soil, the indices of product quality and yield, and also the content of certain microemoietic substances in raw materials. Instrumental laboratory ((infrared spectrometry, atomic-absorption photometry, flame spectrophotometry) and statistical analysis methods (Statistica 13.3) were used. The analysis of archival soil samples and plant raw materials provided by the Department of Long-Term Experiments of the All-Russian Scientific Research Institute of Agricultural Chemistry was carried out. In the process of studying the aftereffect of high doses of the organo-mineral fertilizer system and after the renewal of a long field experiment (with continuing and teachings aftereffect and the resumption of mineral fertilizers) allowed to outline the dynamics of changes of soil agrochemical indicators and the dynamics of change of indicators of quality of production and productivity ("Stationary Shebantsevo Modified, No. 5").
