Research And Field Test Of The Bio-Organic Fertilizer With Higher Nitrogen Content

On the base of the field tests,the research of the various organic fertilizers were carried out on the yield and quality of vegetables. For solving the problem of lower nutrient content of organic fertilizers,the urea chosen from the mineral fertilizers was putted into organic material. The inorganic nitrogen releasing from the urea was converted into organic nitrogen through the anaerobic fermentation ,in order to make a new kind of bio-organic fertilizer with higher nitrogen content,which has not on -ly higher nutrient content like chemical fertilizers but also slow release nutrient like organic fertilizers.The nitrogen nutrient is utilized effectively by plant and not lost easily.In this way,the environmental quality is protected.The field test indicated that:the yield of cabbage was increased by 49%,compareing the organic fertilizer with higher nitrogen content with common urea .
