The main types of organic fertilizer raw materials can be divided into the following categories:
1. Agricultural waste: such as straw, soybean meal, cottonseed meal, etc.
2, animal manure: such as chicken manure, cow dung, sheep manure, horse manure, rabbit manure;
3. Industrial waste: distiller's grains, vinegar grains, cassava residue, sugar residue, furfural residue, etc.;
4, domestic garbage: such as kitchen garbage;
5. Urban sludge: such as river sludge, sewage sludge, etc.
Then, how to buy high-quality and cheap organic fertilizer raw materials, we give you the trick, now in the period of higher and higher organic fertilizer, many organic fertilizer manufacturers have mushroomed, so people are also relatively selective Increased, but there are some manufacturers who cut corners in the face of interests, so everyone should polish their eyes when buying, choose organic fertilizer with better quality, then, do you know how to choose, today we will say:
Organic fertilizer is related to his production process and the level of raw materials used. Organic fertilizer raw materials are technical indicators. If the organic matter does not meet the standards set by China, it will lead to the soil's absorption rate of nitrate nitrogen and soil compaction. Our company's products have reached the technical indicators recognized by China, and added more active 0.25% of PAPM plant sensitizing bacteria, such as: 3U+ series, omnipotent, organic calcium, etc.
The organic fertilizers using industrial grade raw materials are better in nutrient content, water solubility, absorption efficiency, heavy metal content, product stability, etc. than the organic fertilizer produced by agricultural grade raw materials, and the relative price will be higher, so the organic fertilizer produced It will be better.
The technical level of each organic fertilizer manufacturer is different. The organic fertilizer raw material of our company contains double source humic acid, good decomposing degree, no burning root, no smoked seedling, and high activity PAPM strain, with many bacteria and high activity.
