Effectiveness of micro fertilizers MicroSil in grain, grain leguminous and root crop cultivation on sod-podzolic soils | Эффективность микроудобрений МикроСил при возделывании зерновых, зернобобовых и пропашных культур на дерново-подзолистых почвах

In course of the research there was studied the effectiveness of the different species and doses of liguid micro fertilizer ecosil MicroSil in field experiments on sod-podzolic soils with grain, grain-leguminous and root crops. The research was realized in the conditions of the Republic of Belarus. As a result of realized research it was found that a topdressing of winter wheat (Triticum aestivum) by micro fertilizer MicroSil Copper L at various doses promoted to the grain yield by 4.1-4.8 t/ha and spring barley (Hordeum vulgare) 3.6-5.6 kg/ha in the profitability of 116-199% and 135 -143% respectively. At the sod-podzolic light loamy soil the topdressing of blue lupine (Lupinus angustifolius) in the beginning phase of budding liquid microfertilizer MicroSil Boron increased the grain yield by 3.7-4.3 t/ha and increased the crude protein content by 0.6-1.2%. At the sod-podzolic cohesive sandy loam soil a double topdressing of sugar beet (Beta vulgaris var. saccharifera) by liquid micro fertilizers MicroSil Boron and MicroSil Boron.Cuprum in different doses on the background of organic and mineral fertilizers increased the productivity of roots at 23-42 kg/ha, the yield of sugar - by 3.8 -7.2 kg/ha. Topdressing of potatoes (Solanum tuberosum) in the budding phase by liquid micro fertilizer MicroSil Boron provided additional yield of tubers 20-39 t/ha, MicroSil Boron.Cuprum - 31-35 kg/ha. Micronutrient fertilizers had no significant, effect on the starch content in potato tubers. Topdressing of maize (Zea mays) in the liquid phase of 6-8 leaves by micro fertilizer MicroSil Zink.Boron in increasing doses on the background of organic and mineral fertilizers enhanced the yield of green mass at 37-43 t/ha of grain - by 6.7-11.6 c/ha. Micro fertilizer did not exert influence on the content of nitrates in the green mass of maize.
