The research is aimed at studying the peculiarities of distribution of gross nickel in genetic horizons of soil profile of sod- podzolic sandy loamy and sandy soils of agricultural land in the Ryazan region and determining the current background concentration. To solve the set objectives were laid 10 pits up to 150 cm deep in Kasimovsky, Ermishinsky, Shilovsky, Sasovsky, Klepikovsky, Kadomsky districts of the Ryazan region in the period from 2016 to 2023, analyzed the depth and features of the structure of soil layers, the influence on the conditions of nickel migration. According to the results of nickel content determination the calculation of background concentration was performed. The comparative analysis of the proposed modern regional background value with well-known values of global and domestic researchers: approximate background concentrations for the average strip of Russia, hygienic standards characterizing the approximate permissible concentration of the substance in the soil, soils of the world according to the materials of the international geochemical atlas, soils of the world according to A.P. Vinogradov, global, zonal, regional values of the background according to Y.E. Saet, data of other researchers on the Ryazan land. The structure of soil profiles of soil at a depth of 110-130 cm has the following form: O – A - EL - ELBt - Bt - BtC - C. At the same time weakly noticeable geochemical barriers are noted in horizons A and Bt. Values of gross nickel were located in the concentration range of 3.3 - 16.8 mg/kg. A background concentration of 9.5 mg/kg was proposed, which differs from the generally known values presented in the comparative analysis and gives a modern idea of the regional background content of the gross form of nickel.
