Abstract
Aims: The objective of this study was to examine the distribution of microorganisms in different types of agricultural soils.
Study Design: Comparative analysis of quantity of microorganisms in a crop rotation and constant (permanent) in a dry subtropical zone in different types of soils.
Methodology: Microorganisms quantity has been defined by (microorganisms total quantity meat-peptone-agaric (MPA) and starchy-ammoniac-agaric (SAA), actinomisets starchy - agaric- agaric (SAA) and microscopic fungus quantity have been defined on Chapek agaric environment on the basis of the method received in the Institute of Microbiology of Moscow.
Results: The results showed that the quantity of microorganisms in a crop rotation was more, than permanent cultivation of these cultures. A mineralization of organic substances in soils under constant cultures occurred more intensively, than in a crop rotation.
Conclusion: Including in a crop rotation of legume cultures (Lucerne, haricot, bean) increases quantity of microorganisms, also slows down intensity mineralization of organic substances.
Keywords: Irrigative soils of dry subtropical zones, quantity of microorganisms, crop rotation, constant (permanent) cultures, coefficient of mineralization
