[Effect of combined application of bioorganic manure and inorganic nitrogen fertilizer on soil nitrogen supplying characteristics].
Pot experiment was carried out to study the effect of application bioorganic manure on soil nitrogen supplying characteristics. Compared with the application of raw rice straw, a combined application of bio-organic manure and inorganic nitrogen fertilizer could boost the content of microbial biomass carbon and nitrogen, and the increased percentage could be 300-400%. A strong immobilization of nitrogen by microorganisms was always followed by a net N mineralization, which was mostly favorable for the growth and development of plant, and improved the use efficiency of nitrogen fertilizer.
