Fall soil testing and fertilization - use farmyard fertilizer

Compost, green manure, and manure are collectively referred to as farmyard manure. Although they all contain nutrients such as nitrogen, phosphorus, and potassium, their properties vary, and the range of use varies from fertilizer to fertilizer. The rational use of farmyard manure can not only increase the yield and quality of crops, but also improve soil structure. Compost It is a fertilizer made from a backlog of weeds, garbage, etc., which can be used in accordance with local conditions. It is best to use spring and autumn tillage as base fertilizer. The green manure is best used as base fertilizer or top dressing of legumes, and the nitrogenous effect of rhizobia is used to increase soil fertility. Pig manure contains more organic matter and nitrogen, phosphorus and potassium, and decomposed pig manure can be applied to all kinds of soils, especially for well-drained hot soil. Cow dung has a low nutrient content and is a typical cold fertilizer. Dried cow dries, mixed with 3% to 5% of grass ash or rock phosphate powder, horse dung for accumulation, can accelerate the decomposition of cow dung, improve fertilizer efficiency. It is best used in combination with hot fertilizers or on sandy loam and sunny slopes. Sheep manure is a hot fertilizer and should be mixed with pig manure, suitable for cold soil and shady slopes. Horse manure has a high content of organic matter, nitrogen and cellulose, contains high-temperature fiber-decomposing bacteria, and has high fermentation speed and high calorific value. It is suitable for soils with heavy viscous and heavy soils, as well as shady slopes and severely compacted soils. Poultry manure has high nutrient content and can be used as seed fertilizer and top dressing. It is most suitable for Vegetables. Human fecal urine can be used directly after fermentation, and it can also be mixed with soil into large manure for topdressing.
