Compost, green manure, manure, etc. We collectively call it a farmyard fertilizer. Although these fertilizers contain nutrients such as nitrogen, phosphorus, and potassium, their properties are different, and the scope of use varies from fertilizer to fertilizer. The rational use of fertilizers can not only increase the yield and quality of crops. And can improve soil structure. The following describes the correct use of several common farmyard fertilizers as follows for farmers' friends to use in production and practice. One, compost Weeds and waste can be used as a raw material and can be used locally. It is best to use spring and autumn tillage as base fertilizer.

Third, sheep dung It is a thermal fertilizer and should be mixed with pig manure. It is suitable for cool soil and shady slopes. Fourth, pig manure Organic matter and nitrogen, phosphorus, and potassium are abundant, and decomposed swine manure can be applied to various soils, especially for well-drained hot-water soils. Fifth, horse dung Organic matter, nitrogen, cellulose content is high, contains high-temperature fiber-decomposing bacteria, rapid fermentation in the accumulation, high heat, suitable for wet heavy soil and shady slopes and severely compacted soil. Six, cow dung With low nutrient content, it is a typical cold fertilizer. It is dried in the sun and mixed with 3-5% of grass ash or rock phosphate or horse dung. It can accelerate the decomposition of cow dung and increase fertilizer efficiency. Fertilizers are used in combination or on sandy and sunny slopes. Seven, human waste Fermentation can be used directly after maturity. It can also be mixed with soil to make large excreta for top dressing.
