Common types of farmyard fertilizers and methods of use, straw fertilizers, various crop straws contain a considerable amount of nutrients, and have the effect of improving soil physical, chemical and biological properties, increasing crop yield. Due to the different types of crop straws, the amount of nutrients contained in the crops is also different. Generally speaking, legume crop straws contain more nitrogen, and grass crops contain more potassium.
Straws are directly returned to the field: the pressure is returned to the field, and the straw is crushed and then sprinkled or wrecked directly into the soil. Cover the field, cover the crop straw directly on the soil surface or leave the crop properly when harvesting.
Green manure can provide the necessary nutrients for crop growth. Green manure crops improve soil physical and chemical shape through its strong root interpenetration and overpressure to increase soil organic matter accumulation. Most of the green manure crops have strong resistance to stress, can grow in poor soil conditions, and play a role as a pioneer crop for improving barrier soils. Planting and rolling of green manure can reduce nutrient loss and protect the ecological environment. In special significance, planting green manure can improve crop sputum and so on.
Cake fertilizer and bad residue fertilizer, including bean cake, cottonseed cake, peanut cake, sesame cake, castor seed cake, sunflower seed cake, vinasse, soy sauce residue, vinegar residue, monosodium glutamate residue, powder residue and the like. Cake fertilizer contains a lot of organic matter, protein, residual oil and vitamins, rich in nutrients and high nutritional value. It is both high-quality organic fertilizer and high-quality livestock feed.
The slag fertilizer is a by-product of the agricultural product processing industry, and the original raw materials are all foods, and the nutritional value is also high, but the different raw materials and different processing levels make the components and nutrient contents different. Such fertilizers generally need to be fermented before they can be applied. The fermentation method is to crush the cake fertilizer (not required for the residue), and then tanning it with human excrement or with the manure and compost, and pay attention to nitrogen retention during the tanning process.
Soil and fertilizer include all kinds of soil and fertilizer (boiled soil, smoked soil, and nitrate soil), mud fertilizer (river mud, lake mud, pond bay mud, sludge from fish farms, etc.), fertilizer water, grass ash, and domestic garbage. The nutrient content of this type of fertilizer is relatively low, and the composition of the fertilizer is relatively complicated. The collection and application should be based on the relevant standards for farmland environmental protection.
