One of the tasks facing the agrochemistry is the search for fertilizers of prolonged action, with the gradual release of nutrients and having aftereffect. Under the conditions of a stationary field experiment on soddy-medium-podzolic light loamy soil in the conditions of the Northern Non-Black Soil Zone, the effectiveness of organic- mineral fertilizer (OMF) made on the basis of lowland peat with the addition of macro- and microelements, as well as humic acids manufactured by OAO the Buyskiy Chemical Plant has been studied.

Submitted by red on Wed, 25/04/2018 - 13:53

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.
