STATE OF FERTILITY OF ARABLE SOILS IN THE TAIGA-FOREST ZONE OF THE OMSK REGION

The arable soils of the region were characterized by low and medium levels of fertility. Within each field, soil fertility indicators varied over a wide range. The humus content varied from 2.2 to 7.3%. pH varied from moderately acidic to neutral. The composition of exchangeable cations characterized by high magnesium content - from 2.5 to 9.5 mmol/100 g of soil. In the aggregate composition of soils the amount of agronomically valuable fractions was 45.2-61.0%, blocky aggregates - 14.8-36.5%, dust - 8.7-36.9%.

Abstract

The arable soils of the region were characterized by low and medium levels of fertility. Within each field, soil fertility indicators varied over a wide range. The humus content varied from 2.2 to 7.3%. pH varied from moderately acidic to neutral. The composition of exchangeable cations characterized by high magnesium content - from 2.5 to 9.5 mmol/100 g of soil. In the aggregate composition of soils the amount of agronomically valuable fractions was 45.2-61.0%, blocky aggregates - 14.8-36.5%, dust - 8.7-36.9%.
