Application of geostatistical approach in accounting for intra-field heterogeneity soil acidity In liming of agricultural lands

Abstract

The article presents the main stages of mapping agrochemical properties of soils by geostatistical method on the example of soil acidity. The comparison of costs for carrying out works on liming of arable land by classical and geostatistical method of mapping soil acidity on the example of JSC «Koshelevo-Agro» is carried out. The following were taken into account: cost of sampling and laboratory analysis; costs of liming.

The total cost of liming works, including procurement, transportation and application, as well as sampling and laboratory analyses, was 39976 BYN for the classical method and 40935 BYN for the geostatistical method, which is 959 BYN more. However, using the classical method, only 72,5 % of the amount spent would have been effectively utilized.
