Corn fertilization at crop cultivation on typical chernozem in Forest-steppe

S. P. Tanchyk, L. Tsentylo

Анотація


The effect of different types and doses of fertilizers in combination with microbial preparation Polymixobakteryn and stand-alone on nitrogen fixation and biological denitrification in rhozosphere soil of corn was studied in long-term stationary field experiments. The conducted research have indicated that the most ecologically expedient doses of fertilizers were the ones that do not exceed N90P90K90. It was shown that fertilizer efficiency was higher in the variants with microbial preparation Polymixobakteryn. Economically and environmentally attractive use of manure was also confirmed in corn growing technologies. Due to the high level of N2O emissions accompanying manure application the receipit and use of compost from manure is required. Application of manure and biocomposts offsets the pre-sowing seeds bacterization efficiency and should be taken into the account when planning crop fertilization systems.
