Humic acid biofertilizer production method

Humic acid is a kind of natural macromolecule organic acid compound widely existing in nature. It is abundant in soil, peat, lignite, weathered coal and water. It is formed by the biological and chemical effects of animal and plant residues over a long period of time. Humic acid biofertilizer can improve soil environment and fertility. Here is a production method of humic acid biofertilizer.

1. First, crush the weathered coal, and then screen the material with screener machine. The weathered coal fines are further processed.
2. Adjust the moisture content of weathered coal to 30%, add 10% monovalent ions and 20% stabilizers, mix evenly, and place them at room temperature for 1-2 days, stirring once every 6 hours.
3. Spraying 0.01% fertile soil water extract and 0.1% active primers evenly for 7 days at 20-30 C, then drying at 60 C.
4. After mixing the treated weathered coal with urea and potassium sulfate, the humic acid biofertilizer was produced by the process of bio-organic fertilizer production line.
Bio organic Fertilizer Production Line
The biofertilizer produced by this method can not only provide nutrients but also improve soil water storage capacity. It plays a great role in arid and semi-arid areas. This kind of biological fertilizer is suitable for areas with low soil organic matter content and small amount of soil aggregates, and can increase the ability of soil to maintain precipitation.
