3. Use

Humic acid powder can be used as a low-cost fertilizer filler, raw material for soil improvement, raw material for the production of humate, green planting.

(1) Green planting:

Mixed application with chemical fertilizer reduction: 2250-7500kg/ha, used with NPK, the amount of chemical fertilizer can be reduced by about 10%, humic acid improves the utilization rate of fertilizer in the season and reduces leaching by controlling nitrogen, releasing phosphorus, and promoting potassium.

(2) When humic acid is used as a soil amendment, it can be used in the following ways:

Spreading and tillage: Sprinkle humic acid raw powder or granular (300-750 kg/ha) evenly on the surface and mix with the cultivated soil (15-20 cm) to quickly improve the aggregate structure, reduce the bulk density, and improve the water and fertilizer retention capacity.

Combined with organic fertilizer/bacterial fertilizer: adding 30-50 kg of humic acid per ton of compost or manure can shorten the decomposition time by about 30% and increase the number of beneficial bacteria by more than 50%.

Saline-alkali land improvement: 600-900 kg of humic acid per hectare (preferably with gypsum or desulfurized gypsum) can reduce soil pH by 0.3-1.0, reduce Na⁺ content by more than 80%, and significantly improve seedling emergence rate and yield.

Acidified soil: "Alkaline humic acid soil conditioner" is selected according to the pH grading table (pH<4.5 strong acidity), the recommended amount is 450-900 kg/ha, and the pH adjustment amount is monitored year by year.

Precautions: A small amount taken multiple times is better than a large dose taken once; applying it together with microbial agents can enhance its effectiveness.
