Humic Acid Granule

Humic acid granules, also known as humic acid granular fertilizer, refer to an organic fertilizer processed from peat (peat), lignite, weathered coal, etc. as the main raw materials. The main raw material is humic acid raw powder, which is composed of carbon, hydrogen, oxygen, sulfur and other elements. It can also absorb a large amount of trace elements such as potassium, ammonium, magnesium, iron, manganese, copper, zinc and so on. After being applied to the soil, it can be used for plants. Continuous long-term supply of nutrients.

Its organic matter content is more than 70% to 80%. When applied to soybeans, wheat, corn, potatoes and other crops, the yield increase is obvious. When applied to soybeans, the yield per hectare was 2,500 kg, an increase of 8.7% compared to the control; when applied to wheat, the yield per hectare was 3,850 kg, an increase of 8.1% compared to the control; and potato yield was increased by 18.0%.

Usage Method and Precautions

(1) Humic acid granular fertilizer is suitable for use on crops with a long growth period. For example, when applied to crops such as soybeans, corn, potatoes, sugar beets, etc., it can exert its long-lasting effect. If applied continuously for many years in the same plot, the effect will be more significant, and it can improve the soil in barren plots.

(2) Use humic acid granular fertilizer to replace 25% to 30% of chemical fertilizers and mix it with chemical fertilizers. For example, 120 kg of diammonium phosphate, 70 kg of urea, and 40 kg of potassium sulfate are routinely applied per hectare. After mixed with humic acid granular fertilizer, the application of chemical fertilizers per hectare can be reduced to 80 kg of diammonium phosphate, 40 kg of urea, and 20 kg of potassium sulfate. The cost can be saved by 80 to 100 yuan per hectare (humic acid granular fertilizer is priced at 1,200 yuan/t).

(3) Humic acid granular fertilizer can be used as base fertilizer and seed fertilizer, but cannot be used as top dressing. When used as seed fertilizer, mix it evenly with chemical fertilizers and then apply it deeply in layers at a depth of 7 to 14 cm; if used as base fertilizer, the fertilizer can be deeply sandwiched in the ridge body during soil preparation and ridge formation in spring and autumn. Humic acid fertilizer cannot be used alone, nor can it completely replace chemical fertilizers.

Characteristics of Humic acid granule

(1) Fertilize the soil and improve the physical and chemical properties of the soil. Long-term application can make the soil fertile, especially in barren lands and soybean fields that have been cropped for many years, and the effect is more significant.

(2) Improve fertilizer utilization, preserve nitrogen, increase phosphorus, activate potassium and trace elements, and enhance nutrient absorption. During the entire growth period of the crop, the company continuously provides various nutrients required for crop growth, and it is not easy to lose fertilizer in the later period.

(3) Promote root development, maintain strong seedlings, accelerate plant metabolism, promote the accumulation of organic matter, and improve the nutritional status of crops.

(4) Preserve water and resist drought, increase ground temperature, enhance plant stress resistance, reduce damage from diseases and insect pests, and promote early maturity.

(5) Increase the microbial community in the soil, alleviate the pollution of heavy metal ions in the soil, and mitigate phytotoxicity.

(6) Low cost, which can reduce fertilizer input costs.
