What are the advantages of farm manure? Farm manure mostly refers to human and animal waste and other fertilizers. Such as human dung urine, pig, cow, sheep, horse dung urine, poultry manure and stable compost, compost, biogas fertilizer, smoked soil, Kang soil, plant ash and so on. Its main characteristics are as follows: first, the source of farm manure is relatively wide, and the cost is low. Farm manure is basically based on local materials in rural areas, so it has a wide range of sources and low cost. Second, farm manure contains more comprehensive nutrients, and the fertilizer effect is stable and lasting. Farm fertilizer contains not only nitrogen, phosphorus and potassium, but also calcium, magnesium, sulfur, iron and various trace elements, as well as some substances that can stimulate root growth and a variety of beneficial soil microorganisms. Third, farm manure can improve soil structure. Farm manure is rich in humic acid, which can promote the formation of soil aggregate structure, make the soil soft, improve soil moisture and air conditions, benefit the growth of roots, increase the performance of soil fertilizer and water conservation, and improve soil temperature. it can also promote the activity and reproduction of beneficial microorganisms in the soil. Fourth, the fertilizer effect of farm manure is slow but long. Most of the nutrients in farm manure exist in complex organic form, which needs to be transformed and decomposed by microorganisms in order to release a variety of available nutrients for crop absorption and utilization. This process is relatively slow, but the fertilizer effect is relatively long. Its fertilizer effect can last for 3 to 5 years. Therefore, farm manure is only suitable for base fertilizer, but generally not suitable for topdressing and planting fertilizer. Fifth, the nutrient content of farm manure is low. The nutrient content of all kinds of farm manure is very low, and the application of farm manure alone is far from meeting the nutrition needs of crop growth, so it is necessary to increase the application of chemical fertilizer to make the two complement and promote each other in order to achieve the combination of land use and cultivation of land. the goal of high and stable crop yield. Sixth, farm manure can be divided into heat, temperature and coolness, and has the effect of regulating soil temperature. Generally speaking, horse, sheep, poultry and rabbit manure belong to hot fertilizer; human manure, pig manure, compost and all kinds of mud fertilizer belong to cool fertilizer. Different farm manure can be used to adjust soil temperature in production. Practice has proved that farm manure is an excellent organic fertilizer in agricultural production. The characteristics and functions of farm manure can not be replaced by chemical fertilizer. even in the case of the development of a large number of chemical fertilizers, the application of farm fertilizer is indispensable. The application of farm fertilizers combined with chemical fertilizers can not only reduce production investment and increase income, but also reduce groundwater pollution caused by large amounts of chemical fertilizers.
