Impact of advanced soil conservation technologies for growing maize on sloping terrains on soil microbiota

Water erosion leads to the loss of soil, nutrients, organic matter, disruption soil structure, reduction moisture capacity, biodiversity, and is most significant degradation process when growing agricultural crops on sloping terrain. Soil microorganisms are basis functioning ecosystems, circulation substances, soil-forming processes formation structure. Microbiological indicators, such as numbers, microbial biomass, enzyme activity, etc., a sensitive indicator changes that have occurred in under influence anthropogenic or natural impacts. The present study abundance major groups microorganisms, applying different tillage systems maize was carried out Carbonate Black Earth, at Experimental Station for Combating Erosion, IASSPP “N. Pushkarov”, village Trastenik, Ruse, Agricultural Academy - Sofia. A field experience with corn grain, traditional anti-erosion technologies (surface vertical mulching) corn, presented. obtained results show positive applied protection number saprophytic bacteria, mold fungi, actinomycetes, nitrogen-fixing cellulose-degrading microorganisms.
