Organic fertilizer is a fertilizer composed of organic substances. It contains a large amount of organic matter and many nutrient elements. It has a wide source, is easy to build, has a long lasting fertilizer effect, is conducive to fertility, improves soil, and improves crop quality. It is an important fertilizer for agricultural production. The source plays an important role in fertilizing fertility, increasing crop yield and improving quality. According to the differences in its accumulation and development, it can be divided into the following five major categories.
Farm fertilizer
With animal manure, human waste, compost, and cake fertilizer as the main sources, it has a wide source and a large stock. It is currently the main organic fertilizer source in rural areas.
Role: Farmyard manure generally contains more organic matter, improves soil, fertilizes fertility, improves soil water conservation, fertilizes fertilizer, and ventilates. It also contains nitrogen, phosphorus, potassium, calcium, magnesium, iron, zinc, boron, Manganese and other mineral elements can provide comprehensive and lasting supply of crop nutrition.
Crop straw
In addition to organic matter, straw also contains nitrogen, phosphorus, potassium, and various kinds of trace elements.
Role: A large number of production practices have demonstrated that straw is applied directly to the soil and has significant fertility, soil conservation and other effects.
Green manure
Clover, grass hibiscus, etc. are all green manure crops.
Role: It can protect the roots, biological nitrogen fixation in roots, but also overturn fertilization soil, so has been recognized by the majority of fruit farmers, have spontaneous planting; Second, the cultivation of earthworms, Rumex and other green manure crops, can be fertilizer, It can also be used for pasture to return to the field.
Biogas Fermented Fertilizer, Marc & Mushroom Residues
With the development of the fruit processing industry, a large amount of fruit slag produced in fruit wine and juice plants, orchard pruning organic materials such as twigs and smashing to produce mushroom products, is a good organic fertilizer through heap rot fermentation. There are also tens of thousands of tons.
Role: The rapid development of biogas utilization, the construction of biogas digesters is an effective use of various types of straw, human waste, in addition to play a role in combustion, lighting, a biogas digester can also produce 10 cubic meters of biogas fertilizer each year.
Organic fertilizer
Mainly refers to the production of refined organic fertilizer, organic-inorganic compound fertilizer. The selected organic materials are mostly weathered coal, peat, chicken manure, etc. This type of fertilizer has both inflows from overseas and production by local fertilizer companies. Some farms also sell animal manure directly.
Role: Commodity organic fertilizer is an important fertilizer source for agricultural production, and plays an important role in fertility improvement, crop yield improvement and quality improvement.
