BIOLOGICAL NITROGEN TRANSFORMATION IN AGROCENOSES OF POTATO AND PRODUCTIVITY OF CULTURE IN ORGANIC AGRICULTURE
Journal Title: Сільськогосподарська мікробіологія - Year 2016, Vol 24, Issue
Abstract
The effect of organic fertilizers (cattle manure and lupine green manure), as well as microbial preparation Biohran on the dynamics of the activity process of nitrogen fixation and N2O emissions in the rhizosphere soil of potato plants, crop yield, and product quality have been investigated. The use of manures stimulates activity of nitrogen fixation, but at the same time, accompanied by a significant loss of gaseous nitrogen compounds. The efficiency of Biohran by this agrobackground is largely levelled. Lupine green manure stimulates nitrogenase activity, especially in combination with biopreparation. At the same time, there is a tendency to reduce nitrous oxide emission. Organic fertilizers contributed to a reliable raise of potato yield. Biohran provide productivity gains only on the background of green manure. Microbial preparation contributed to the improvement of quality of production parameters by all studied agrobackgrounds.
