What is the role of humic acid fertilizer? What are the correct methods of application? Humic acid fertilizer is a popular fertilizer on the market. It has many manufacturers and many people. Therefore, today Xiaobian will briefly talk about the role and application method of humic acid fertilizer, and hope to help everyone.

[humic acid fertilizer]

(1) Humic acid fertilizer raw materials

A black solid (or liquid) fertilizer made by combining natural resources such as peat, lignite, and weathered coal containing humic acid with a substance containing ammonium, sodium, potassium, calcium, and magnesium.

(2) Effect of humic acid fertilizer on soil

It has a chelation and adsorption effect on many nutrients, providing nutrients for soil and crops, and providing soil active substances.

(3) Advantages of humic acid fertilizer

a. Loose soil and cultivate soil fertility and soil fertility.

b. Provide nutrients for crop growth.

c. It can absorb nutrients such as ammonium ions and potassium ions, and reduce nutrient loss.

d. It is especially important for fertilizers such as ammonium bicarbonate and ammonia.

e. Enhance the activity of various enzymes in crops and stimulate crop growth.

f. Promote the ability of microorganisms to multiply and move, and have a stimulating effect on microorganisms.

g, effectively improve the activity of fungi, bacteria and nitrogen-fixing bacteria, and promote the decomposition of organic matter.

h. Shorten the time of full maturity of farmyard manure and promote the release of available nutrients.

i. It has obvious synergistic effect on fertilizer.

j. Improve the drought resistance, cold resistance, salt and alkali resistance of crops.

k. It can effectively improve the disease resistance of grain, cotton and vegetable crops.

l Improve the utilization rate of fertilizer.

[Humic acid fertilizer types]

(1) Humic acid

a. Humic acid fertilizer is a combination of grass charcoal or peat and chemical fertilizer.

b. The main products of humic acid are: humic acid ammonium, humic acid phosphorus, humic acid potassium, humic acid, humic acid NPK compound fertilizer, nitro humic acid ammonium, nitro humate potassium and other nitro compound fertilizers.

(2) fulvic acid

a, fulvic acid is divided into two categories of solid and liquid.

b, the main products of fulvic acid are: yellow sulphate diamine iron, potassium fulvic acid, sodium fulvate, fulvic acid urea iron, zinc fulvic acid, fulvic acid compound fertilizer, fulvic acid trace elements.

[Human acid fertilizer application method]

(1) in agricultural production

a, used for base fertilizer, top dressing, seed dressing, root irrigation, drip irrigation or rinse with water.

b. Use 0.02-0.05% aqueous solution 300-400kg per mu.

c. In the seedling stage and heading stage of the crop, 250kg of 0.01-0.1% aqueous solution is watered in the root system per acre.

(2) Rice fields

a. Seed dressing with potassium fulate, when applying fertilizer, generally apply 5-10kg per acre, and mix better with urea or other compound (mixed) fertilizer.

b. After the flowering of the paddy field to the initial stage of filling, 50-75kg of 0.01-0.05% aqueous solution per acre is sprayed, which is beneficial to the fullness of the grain, increase the grain weight and reduce the openness.

c. Fertilization time is appropriate in the evening.
