The influence of various kinds, forms, dozes of fertilizers and their combinations on fertility these ground, efficiency crop rotation and separate agricultural cultures, quality of a crop is investigated. The high rates degradacion without fertilizers grey wood ground are established and efficiency of a combination in a grain - beet crop rotation inform(notify), organic, mineral, macro- and microfertilizers, that allows to reach(achieve) and to support high (up to 102 c/ha of grain units) a level of efficiency. By a complex estimation long (28 years) application of various systems of fertilizers in a grain-flax-potato crop rotation on easy дерново-подзолистых почвах are established, that separate systems (organic fertilizers and their combination with mineral at a parity(ratio): on one ton of organic fertilizers till 12-13 kg NPK) are not limited in time, whereas the application of other systems is limited to 7-21 years, the ignoring that can result in negative consequences, switching toxicos of ground and sharp reduction of efficiency. Are developed and are recommended to manufacture of a way of renewal of fertility easy дерново-подзолистых почв with agrohimic toxicos, which consist in intensive application during three years of organic fertilizers (muck, peat, sapropel) in various combi-nations, application abnormaly high of dozes of phosphoric fertilizers and microfertilizers. The soil conditions for an effective utilization local phosphorits are certain(determined) at fertilizer of a potatoes, winter wheat and flax. Local окультуривание sour grounds saves organic fertilizers in 6-7 times and mineral in 1,5 times Product Description popup.authors popup.nrat_date 2020-04-02 Close
