Intra-field variability of soil acidity for differentiated application of ameliorants
AIn the materials of this article the results of agrochemical survey of fields using satellite navigation systems for the development of measures for the introduction of ameliorants are shown. The introduction of innovative technologies in the field of crop production requires increased attention to the system of mineral nutrition of crops, and the effectiveness of the latter depends on the acidity of the soil. Agrochemical analysis of the soil showed a high uniformity of hydrolytic acidity in the elementary areas of the fields from 15.2 to 46.2 %, which indicates a high and medium diversity of hydrolytic acidity.
