ABSTRACT
The article presents the problems of agrochemical research based on practical experience conducted in the existing chemical and agricultural stations in Poland. The results of research on soils used for agriculture in the years 1955-2017 are presented. Soil testing is carried out for the needs of advising on the use of fertilizers on farms in order to intensify plant production. The results of this research are also used to develop maps of pH and abundance of soil in absorbable forms P, K and Mg, which are systematically published in the statistical yearbooks of the Central Statistical Office. The result is to determine the state of contamination of agricultural soils with heavy metals and to determine the hazard classes for these elements in the cultivation of plants. In addition, increased sulfur content in Poland's soils was found and hazard zones were identified for this constituent. The concentrations of phosphorus, iron and aluminum were also determined, which allowed to limit the soil phosphorus indicator, which is characterized by soil saturation or sorption capacity. The presented works takes of reducing the impact of agricultural activity on the environment, in connection with the improvement of the quality of produced food.
