Analysis of the role of humic acid granular fertilizer

Humic acid granule fertilizer refers to an organic fertilizer processed from peat (cep charcoal), lignite, and weathered coal. Humic acid is an organic substance accumulated by a series of transformation processes of animal and plant residues after years of weathering, microbial decomposition, and earth changes. It is widely found in peat, lignite and weathered coal. Humic acid is composed of various elements such as carbon, hydrogen, oxygen and sulfur. It can also adsorb a large amount of trace elements such as potassium, ammonium, magnesium, iron, manganese, copper and zinc. After being applied to the soil, it can continuously supply nutrients for plants. . Humic acid also contains a large amount of organic matter, which not only has the multifunctional effect of farmyard manure, but also has the quick-acting characteristics of chemical fertilizer, so it is called a multifunctional organic-inorganic compound fertilizer.

1 Application effect Since 2004, the author has selected humic acid granular fertilizer produced in Jixi City, Heilongjiang Province, in soybean (Beifeng No. 10), wheat (gram 813), corn (Jidan No. 4), potato (KX12). ) When applied on crops, the yield increase is more obvious. In 2004, 2.5 hm2 was applied to soybeans, and the yield per hectare was 2500 kg, which was 8.7% higher than that of the control; 28.5 hm2 was applied to wheat, and the yield per hectare was 3850 kg, which was 8.1% higher than the control. In 2005, it was tested in Keshan Farm of Heilongjiang Province, Shenyang Air Force Food Base, Keshan and Nehe. The average soybean yield increased by 8.5% and the potato yield increased by 18.0%. The Jiu San Branch of Heilongjiang Land Reclamation has been widely promoted since 2000. The soybean application area has reached more than 13.3 million hm2, increasing production by 2.0% to 18.5%.

2 Usage and precautions a. Humic acid granular fertilizer is suitable for application in crops with long growing season. If applied on crops such as soybean, corn, potato, and sugar beet, it will be more effective. Continuous application in the same plot for many years, the effect is more significant, and it has the effect of improving soil on barren land.

b. Replace 5% to 30% of chemical fertilizer with humic acid granular fertilizer, and mix with chemical fertilizer. For example, 120 kg of diammonium phosphate, 70 kg of urea and 40 kg of potassium sulfate per hectare can be reduced to 80 kg of diammonium phosphate, 40 kg of urea and 20 kg of potassium sulfate after mixing with humic acid granular fertilizer. The cost per hectare can be 80-100 yuan (the humic acid granular fertilizer is priced at 1200 yuan/t).

c. Humic acid granular fertilizer can be used as base fertilizer and seed fertilizer, and can not be used as top dressing. When planting fertilizer, the same fertilizer is evenly mixed and layered deep, with a depth of 7 to 14 cm; if it is used as a base fertilizer, it can be ridged in the Spring and autumn when the ridge is deep. Humic acid fertilizer should not be used alone or in place of fertilizer.

3 Function characteristics a. Fertilize the soil and improve the physical and chemical properties of the soil. Long-term application can make the soil fertile, especially the thin and long-term heavy soybean fields, the effect is more significant.

b. Improve fertilizer utilization, maintain nitrogen, increase phosphorus, activate potassium and trace elements, and enhance nutrient absorption. During the whole growth period of the crop, the company continuously supplies all kinds of nutrients needed for crop growth, and it is not easy to remove fertilizer in the later stage.

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

d. Water retention and drought resistance, increase ground temperature, enhance plant resistance, reduce pests and diseases, and promote early maturity.

e. Increase the microbial community in the soil, alleviate the pollution of heavy metal ions in the soil, and slow down the phytotoxicity.

f. Lower cost can reduce the input cost of fertilizer.
