The Effect of Cow Dung and Red Bean Straw Dosage on Soil Nutrients and Microbial Biomass in Chestnut Orchards

This research study on the effect of cow dung and straw Red Bean Dosage on soil nutrients and microbial biomass in Chestnut orchards. The results indicate that: red bean straw and cow dung facilities can significantly increase soil nitrogen, phosphorus, and effective Potassium content and microbial biomass, and times the amount of cow dung fertilizer increase soil nitrogen, phosphorus, and effective Potassium content and microbial biomass significantly, times the amount of the red bean straw fertilizer can increase soil available K, but there is no significant difference to improve nitrogen and phosphorus and microbial biomass. In the application of less, the effect of the Red Bean on soil fertility, straw is better than cow dung, but in the situation of organic farming, require a lot of organic manure, the nutrient supply of cow dung on the chestnut tree's is better than red bean straw.
