Abstract
The invention discloses a method for reducing nitrogen loss in a composting process and improving the fertilizer efficiency of compost products by using iron oxide nanometer materials. The method comprises the following steps: mixing iron oxide nanometer materials with compost raw materials, and composting the obtained mixture. The method of the present invention uses iron oxide nanomaterials to reduce nitrogen loss in the composting process and improve the fertilizer efficiency of composting products, which can not only effectively reduce the nitrogen loss in the composting process, but also improve the fertilizer efficiency of composting products, and has the advantages of simple process, convenient operation, With the advantages of high processing efficiency and good processing effect, it is suitable for large-scale preparation of compost products, and is of great significance for improving the application value and application range of compost products.
Description
technical field [0001] The invention discloses a method for controlling nitrogen loss in the composting process and composting product fertilizer efficiency, and specifically relates to a method for reducing nitrogen loss in the composting process and improving the fertilizer efficiency of composting products by using iron oxide nanomaterials. Background technique [0002] At present, composting technology has been widely recommended as an environmentally friendly, economical and practical way to recycle agricultural waste. During the composting process, agricultural waste is biodegraded into a stable humus-like substance while pathogenic microorganisms are eliminated, allowing it to be recycled as soil amendment fertilizer and remediation agent. The transformation of nitrogen in the composting process is completed by a series of microorganisms, mainly including nitrifying microorganisms and denitrifying microorganisms. The characteristics of nitrogen transport during compo...
