摘要
The nitrogen of organic fertilizers contributes to stabilization of nitrogen cycles and sustainable development of agroecosystems. The application of green manure biomass as organic fertilizer enhances the immobilization of their nitrogen in soil, reduces the nitrogen consumption by plants and its gaseous losses as compared with mineral fertilizers. A combined use of the green manure biomass and mineral nitrogen fertilizers decreases the nitrogen immobilization in soil as well as increases its consumption by plants and its gaseous losses. The application of manure reduces the nitrogen gaseous loss from green manure biomass. The use of the oat and timothy biomasses as a fertilizer decreases the consumption of their nitrogen and soil nitrogen by plants by 18–36 and 6–36%, respectively, while the nitrogen immobilization in soil increases and its gaseous losses decrease by 17% as compared with the application of mineral fertilizers alone.
