Journal Title: Agricultural and Resource Economics: International Scientific E-Journal - Year 2015, Vol 1, Issue 1
Abstract
The research results showed that the use of organic and mineral fertilizers in the grain – fodder crop rotation facilitates improving soil nutritive regime and increasing soil fertility by increasing the content of easy hydrolysable nitrogen, movable phosphorus and exchange potassium in sod – podzolic sandy loam gley soil. Presowing inoculation of maize, field pea and spring barley seeds using such inoculation preparations as rizogumin, mikrogumin and biogran gives a positive effect on soil nutritive regime. This allows to increase the content of nitrogen by 5–10 % and phosphorus – 9–16 %. It was experimentally proved the appropriateness of biogran inoculation preparation use in the biological fertilize system in the sod-podzolic soil of Volyn Polissya region, that allows to increase the productivity of green maize to 40–45 t/ha as well as the rizogumin use allows to increase the productivity of field pea in the organic-mineral system to – 37–40 t/ha. Economic assessment of inoculation preparations use in various fertilize systems while green maize, field pea and spring barley cultivation on sod-podzolic soil was made.
