SEASONAL PHASE OF BIOLOGICAL ACTIVITY GREY-BROWN (CHESTNUT) SOILS OF KARAMARYAM PLATEAU
Activity occurring in the soil biological processes are intimately connected with the climatic conditions, which in some seasons have different effects on the microbial activity engaged in biochemical-nomic transformation of plant residues. Conducted by us researches seasonal quantitative microbiota revealed characteristic differences in natural and cultivated cenoses, which in turn proves to existing Seasonal changes in the activity of microorganisms. Results of the study show that in the first phase in the processing of plant residues in natural cenosis takes 21.44% participation, and alfalfa agrotcenoze 22.85% of microorganisms from the total. The number of microorganisms in the soil of natural cenosis lowest reaching to 300 thousand. le g.pochvy equal to 9.90% of the total microbiota. On agrotcenoze alfalfa as a result of agricultural activities carried out some microorganisms are improved living conditions. Mean while extreme conditions still affect their quantitative indicators.
