Humic acid use approach

(1) Seed soaking use: in potato, garlic, wheat, corn and other crops before sowing, can be used 0.01% humic acid solution soaked seeds for about 5 hours, fished out and dried sowing, can promote seed germination in advance, improve the germination rate, seedling Qi, seedling uniform, seedling strong.

(2) As a base fertilizer: Humic acid can be mixed with compound fertilizer as a base fertilizer, generally 30 to 40 kg of compound fertilizer containing humic acid per mu. This is beneficial to the rooting of seedlings, making them more robust and improving their resistance to cold, drought and disease.

(3) Fertilizer use: When chasing fertilizer, humic acid can be mixed with water-soluble fertilizer and flushed with water, generally with a water solution containing 0.01-0.1% concentration of about 40-50 litres per mu, humic acid combined with ammonium, phosphorus and potassium plasma to form a complex state of fertilizer, which can improve the utilization rate of compound fertilizer , promote fruit expansion and increase yield.

(4) Foliar spraying: in the crop seedling, flowering, fruit expansion can be sprayed, generally per mu with a concentration of 0.1-0.5% humic acid solution 200 ~ 300 ml, mixed with water 30 ~ 50 kg spraying, spraying time should be selected in the afternoon 2-4 pm, nutrients can be fully absorbed by the leaves, so the best results.
