Research on the Migration and Transformation of the Biogas Fertilizer Nutrients

Abstract:

Biogas Fertilizer nutrient contents are different with the different fermentation raw materials. This paper studied the migration and transformation of the nutrients in the raw materials-biogas fertilizer-soil-crop, summarized the correlation between fermentation materials and biogas fertilizer, the influence of biogas fertilizer on soil and crop nutrients. The results showed that: （1）The ratio of phosphorus and nitrogen content in raw materials and biogas fertilizers exceed the crop demand. （2）The inappropriate use of biogas fertilizer will result nitrogen/phosphorus nutrient in soil imbalance, contents of nitrite exceeded the soil standards and crops standards. To achieve the safe use of biogas fertilizer, it must carry out on biogas fertilizer standardization of production and scientific rational utilization.
