The correct use of farmyard fertilizer

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 vary, and the range of use varies from fertilizer to fertilizer. The rational use of fertilizers can not only increase the yield and quality of crops, but also improve soil structure. The following describes the correct use of several common farmyard fertilizers as follows, for farmers' friends to refer to in the production practice. First, the compost of fertilizers made of weeds and rubbish as raw materials can be used according to local conditions. It is best to combine spring plowing and autumn plowing as base fertilizers. Second, green manure is best to do base fertilizer or top dressing of legumes, using the nitrogen-fixing effect of rhizobia to increase soil fertility. Third, sheep feces is a hot fertilizer, should be mixed with pig manure, apply to cool soil and shady slopes. 4. There are more organic matter in the pig manure and nitrogen, phosphorus and potassium, and the decomposed pig manure can be applied to all kinds of soil; it is especially suitable for well-drained hot soil. 5. 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. 6. Cow dung has a low nutrient content and is a typical cold fertilizer; drying cow dung, adding 3 to 5% of the plant ash or phosphate rock or horse dung to accumulate, and accelerating the decomposition of cow dung; improving fertilizer efficiency. It is best used in combination with hot fertilizers or on sandy and sunny slopes. Seven, human fecal urine fermentation can be used directly after decomposed, but also can be mixed with soil into a large dirt as topdressing. Eight, plant ash contains potassium, calcium, boron, manganese and other elements, can do base fertilizer or top dressing. Nine, poultry nutrient content is high, can do fertilizer and top dressing, the most suitable for vegetables. Ten, hole fertilizer is a kind of long-term smoky smoke made from the smoky soil fertilizer, commonly known as soil. From the perspective of effective use, it is advisable to remove one time in 1-2 years. Since the cave soil is dry due to long-term smoke, it should be used for a period of time before the use of water, and then crushed to do base mill or seed fertilizer is better.
