Вестник Ижевской государственной сельскохозяйственной академии ● №4(45) 2015 tillage in a fallow (plowing, nonmoldboard processing) on the biological activity, nitrifi cation and ammonifi cation capacity of the soil, nutrient status, the physicochemical properties of the soil, soil structure and content of waterstable aggregates. <...> Cattle manure application 60 t/ha intensifi ed activities of cellulose-decomposing microorganisms, but suppressed nitrifi ers activity. <...> Embedding of mustard biomass, on the contrary, intensifi ed the activity of nitrifying bacteria, but reduced the activity of cellulose-decomposing microorganisms. <...> Combined application of manure and mustard biomass have optimized activity of cellulosedecomposing and nitrifying bacteria. <...> In the clover green manure fallow with high nitrifi cation capacity of the soil (19.2 mg/kg) accumulation of ammonia nitrogen was observed. <...> Embedding of mustard biomass and clover led to reduction of the hydrolytic acidity of soil to 2.90 and 2.88 mmol/100 g in comparison with pure fallows with manure and without manure, where the hydrolytic acidity amounted 3.36 and 3.42 mmol/100 g. <...> Long-term application of nonmoldboard treatment system of sod-podzolic soil compared with moldboard system showed a decrease in nitrifi cation capacity of soil by 1.2 mg/kg, the degree of decomposition of cloths by 5.03%, an increase in hydrolytic acidity by 0.23 mmol/100 g. <...> Key words: fallows; green manure; mustard; clover; cattle manure; tillage; moisture; cellulose-decomposing activity; nitrifi cation activity; agrochemical parameters. <...> И.И.
