Manure, green manure, and decomposed straw can all be called organic fertilizer.
Organic fertilizer is rich in organic matter and various nutrients, and is the most complete natural compound fertilizer in terms of nutrients. It can not only directly provide nutrients to crops, but can also activate potential nutrients in the soil and increase the content of available nutrients in the soil. Organic fertilizer contains a variety of beneficial microorganisms, which can enhance soil microbial activity and promote the transformation of substances in the soil. Organic fertilizer plays an important role in improving soil and building fertility. Applying organic fertilizer can improve the soil's water- and fertilizer-holding capacity and promote the formation of aggregates in the soil, thereby improving the soil's physical and chemical properties and increasing soil fertility. At the same time, organic fertilizer can also prevent and reduce pollution of the soil by pesticides and heavy metals.
The disadvantages are: low nutrient content and slow fertilizer effect; large application amounts, making transportation and application inconvenient; during periods when crops are growing vigorously and have high fertilizer demand, it often cannot promptly meet the crops' nutrient needs.
There are many types of organic fertilizer, such as manure and urine fertilizer, composted fertilizer, straw fertilizer, green manure, soil and miscellaneous fertilizer, peat, and biogas fertilizer, all of which are organic fertilizers commonly used in rural areas of China.
