Introduction about Raw Materials of Organic Fertilizer

Common plant-derived organic fertilizer raw materials

Straws: Common originals are stover, wheat straw, bean straw, rice straw. Containing high molecular weight substances such as cellulose and lignin, low nutrient content such as NPK (except for legumes), it is rare to use such materials as organic fertilizer alone, and generally used to increase the organic matter of fermented materials and regulate carbon nitrogen ratio. These kinds of raw materials are relatively abundant and the price is low. However, because these materials are mostly in the hands of agricultural retailers, large-area acquisitions are difficult and seasonal, so annual production needs to be stocked in advance.

Oysters: There are soybean meal, cotton aphid, ramie, pepper, peanuts and so on, which are mostly scraps of agricultural products processing industry, mostly auxiliary materials. Organic fertilizers with bismuth as raw materials can be called high-end organic fertilizers, because they are mostly feed grades, the cost of raw materials is high, and fermentation ferment is not suitable for control.

Fungus: Commonly known as mushroom residue, mushroom bag, including mushroom mushroom residue, oyster mushroom residue, oyster mushroom residue, etc. The raw materials are mostly distiller’s grains, corn cob, rice husk powder, wheat bran, soybean meal and some nutrients. The organic matter of the fungus is high. It is rich in bacterial proteins, vitamins, trace elements and auxins. It is better to use organic fertilizers in fertility.
