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 productivity of winter rye on sod-podzolic light loamy soil by using fertilizers and a microbiological preparation

The results of field research conducted on soddy-podzolic light loam soil in the Vologda region established that the use of fertilizers significantly increased the yield of winter rye grain both against the background of the flavobacterin biofungicide and without its use. Depending on the doses of fertilizers and bacterialization with a microbiological preparation, the productivity of straw of winter rye naturally increased, the content of nitrogen, phosphorus, potassium in the production increased, the collection of crude protein by grain and the productivity in feed units increased.
