PROCEDURE FOR DETERMINATION OF THE ABILITY OF SOIL TO SELF-PURIFICATION FROM RESIDUAL PESTICIDE CONTENT

摘要

The invention relates to agriculturally and environment and can be used in the practice agrohimsluzhby, the monitoring service and the research institutes. The aim of the invention is preparation of large-scale maps agricultural soil regions with the ranking of each field of self-cleaning of pesticide residues. For this period poluischeznoveni slabosv bound portion pesticide in the soil, is yuschiys characteristic of self-cleaning ability, determined by the regression equation :. InTso - «+ b + c -pH (Ca + Mg) wherein pH - soil acidity (Ca + Mg) - the content of total exchangeable calcium and magnesium, a, b and c - coefficients depending on the climatic conditions and the pesticide. Thereafter soil separately for each of the climate zones are ranked according to the pH and the content (Ca + Mg) corresponding to a certain self-cleaning ability and conducted mapping area using computer imaging.
