Mycological composition of soils in Kuban rice agrocenoses as a biotic component for their health

Studies of the water-physical, physical-chemical and biological properties meadow-chernozem soils were carried out on a rice irrigation system located in present-day delta Kuban River. Rice have good water general physical humus layers. An increase compaction is observed lower horizons these soils. Meadow-chernozem are distinguished by low content organic matter arable (3,2-3,4 %), neutral reaction soil solution (рН 6,8-6,9) high indices cation exchange capacity (38,7-39,1 mmol/100g). The mycological composition studied autumn-spring periods was identified identified. more saturated with representatives suppressive group at beginning vegetation, opportunistic not detected antiphytopathogenic potential 1:2. spring-fed crop rotations prone to stresses that oversaturated suppressors. In autumn, ratio conditionally saprotrophic pathogenic mycota 1.5:4.5:7. growth colonies micromycete genus Trichoderma traced, which confirms long process slow recovery degradation processes.
