Expediency of taking into account intra­field heterogeneity of soil acidity in liming operations

Abstract

The article presents the main stages of mapping of agrochemical properties by geostatistical method on the example of soil acidity. The comparison of classical and geostatistical methods of soil acidity mapping for the study area was carried out. The comparison was made by the following indicators: cost of sampling and laboratory analysis, costs of liming. Geostatistical method, despite higher costs of sampling and laboratory analysis, 2.9 times more expensive than the classical method, would reduce the cost of liming from 147 rub./ha to 109 rub./ha.
