Introduction about Raw Materials of Organic Fertilizer

Common plant-derived raw materials of organic fertilizer

Straws: Common originals are corn stover, wheat straw, bean straw, rice straw, which contain 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, so generally they are 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, and 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 product processing industry and 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, there are lammulina edodes residue, pleurotus edodes residue, oyster edodes 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 fungus is high, and it is rich in bacterial proteins, vitamins, trace elements and auxins, so using organic fertilizer in fertility is better.
