Description
Summary:This research examined influence of different amounts of bovine manure supplemented with technological wastewater on dominant physiological groups of microorganisms in arable soil layer (0-30 cm) of semigley loess type of soil during silage corn vegetation. Exact fertilizing vegetation experiment was conducted in 2006, in 7 variants and 4 repetitions. Amount of manure supplemented with disinfectants applied in arable soil layer was vital for soil biogenity, what had direct influence on silage corn yield. It was determined that smaller amounts of manure (10-30 m3ha-1) caused slight and relatively short-term decrease in amount of aminoheterotrophs, aminoautotrophs and non-symbiotic fixators of elementary nitrogen (Azotobacter chroococcum), which resulted in silage corn yield of 52.32-54.46 t ha-1of fresh plant mass. While larger amounts of manure (65 m3ha-1) had stronger and long-lasting toxic effects on the same physiological groups of microorganisms, what caused lower silage corn yield (50.08 t ha-1).
