Fertilizers should first be distributed on soils with low fertility. The distribution and application of manure depends on the soil, crops, maturity of the manure, and climatic conditions.
Semi-mature manure, there are a certain number of available nutrients and humus, in addition to the base fertilizer in autumn, but also can be used as a base fertilizer in spring, but not as a fertilizer and top dressing. It is generally used for crops with a long growing period and a vigorous growing season in a hot season, such as corn, potatoes, sweet potatoes, fruit trees, and perennial forages. Generally used for loose texture of sandy soil or sunny slopes, but the amount of each should not be too much, and pay attention to deep application, because the sandy soil permeability is good, manure is easy to decompose. Generally used in areas that are warm and humid or where there are irrigation conditions, or in summer when there is more rainfall and higher temperatures, pay attention to shallow overturns.
The full-body cooked manure can be used as a base fertilizer, but also as a fertilizer and top dressing. When topdressing, it is necessary to cover the soil after application and pay attention to watering. It is generally used for crops with shorter growth periods, such as vegetables and wheat. Generally used for viscous soil, because the fertilizer is good, the amount can be larger, and should not be deep turned; for cold soil, or under wetlands, shady slopes, use of hot fertilizer. In arid, semi-arid, cold regions, or in the spring of dry seasons and low temperatures, it is advisable to use decomposed manure, deep plowing, and usually apply around 2,500 kg/mu. If the main purpose is to improve the soil, the amount of fertilizer can be increased. Fertilization method should be determined according to the quantity and quality of fertilizers. Coarse fertilizer should be fully applied. Fine fertilizers should be used centrally (strips or holes);
