Composting, green manure, manure and so on are collectively referred to as farmyard manure. Although these fertilizers contain nitrogen, phosphorus, potassium and other nutrients, their properties are different, and the scope of use varies from fertilizer to fertilizer. If the fertilizer can be used reasonably, it can not only improve the yield and quality of crops. And it can improve the soil structure. The following is a brief introduction of the correct use of several commonly used farmyard manures for reference by farmers' friends in production and practice.
First, composting. The fertilizer which is made up of weeds and garbage as raw materials can be used according to local conditions. It is best to combine spring and autumn tillage to make base fertilizer.
Second, green manure. It is best to make the base fertilizer or top dressing of legume crops, and use the nitrogen fixation of rhizobia to improve soil fertility.
Third, sheep manure. It is a hot fertilizer and should be mixed with pig manure for cold soil and shady slope.
Fourth, pig manure. Organic matter and nitrogen, phosphorus and potassium are abundant. The mature pig manure can be applied to various soils, especially for well-drained soil.
Five, horse dung. It has high organic matter, nitrogen and cellulose content, contains high-temperature fiber decomposing bacteria, and has fast fermentation and high calorific value in the accumulation. It is suitable for wet and heavy soil and cloudy slope and soil with severe compaction.
Six, cow dung. Low nutrient content, it is a typical cold fertilizer. It is dried and mixed with 3-5% of ash or phosphate rock or horse manure for accumulating. It can accelerate the decomposition of cow manure and improve fertilizer efficiency. Fertilizers are used in combination or applied to sandy soils and sunny slopes.
Seven, human excrement. After fermenting and fermenting, it can be used directly, or it can be mixed with soil to make large manure for top dressing.
Eight, grass and ash. Contains elements such as potassium, calcium, boron and manganese. Can be used as a base fertilizer or top dressing.
Nine, poultry fertilizer. High nutrient content, can be used as seed fertilizer and top dressing, most suitable for vegetables.
Ten, ç‚• hole fertilizer. It is a kind of smoky manure that has been smoked and burned for a long time. From the point of view of effective use, it is advisable to dismantle it once in 1-2 years. Because of the long-term exposure to smoke and fire, the cave soil should be dried for a period of time before use, then crushed for the base fertilizer of millet. Or the seed fertilizer is better.
