The influence of fertilizers on the removal of nutrients by crop rotation in the Vologda region

The productivity of crop rotation on soddy podzolic loam soil in the stationary experience during 2015-2017 was high in the conditions of the Vologda region, especially among annual crops. Winter rye and potatoes also differed by consistently high yield and productivity during the years of research. All the studied cultures showed good responsiveness to fertilizers, especially the calculated doses of their application. The average productivity of crop rotation was 3.30-6.34 tonne cu / ha.

The efficiency of foliar dressings with nano-preparations in increasing the productivity and stability of potatoes to diseases and weeds

As a result of complex investigations conducted in the Tver region in 2013-2015 on well-cultivated soddy medium podzolic sandy loam soil the peculiarities of forming bio-resistance and productivity in three potato varieties (Lyubava, Krasavchik, Nikulinskiy) under the influence of foliar dressings with AgBion-2 and NanoGro preparations having different working liquid concentrations have been studied.
