Integration of humic acid and NPK fertilizer

As a fusion of large fertilizers, humic acid can integrate N, P, K, one-way fusion, two-way fusion or ternary fusion, such as humic acid nitrogen fertilizer, humic acid phosphate fertilizer, humic acid potassium fertilizer, and humic acid compound fertilizer. Humic acid is fused with N, P, and K, which has the characteristics of flexibility and diversity, outstanding functions, significant synergy, and high utilization rate, and can achieve the integration effect of 1+1>2.
Humic acid is organically combined with nitrogen fertilizer to form a quick-acting and slow-release humic acid nitrogen fertilizer, reducing the loss of nitrogen fertilizer and the resulting ammonia pollution. Humic acid provides 10% nitrogen utilization rate, which can increase crop yield by more than 15%.
The combination of humic acid and phosphate fertilizer can reduce phosphorus fixation and improve phosphorus utilization. At the same time, humic acid entering the soil can also activate the fixed phosphorus in the soil and increase the level of soil phosphorus supply. The combined phosphorus supply of the two increases the value of generally 6.7-8.3 mg/kg. Humic acid compound phosphate fertilizer can increase crop yield by 10% the above.
Humic acid is organically combined with potassium fertilizer to form a humic acid potassium fertilizer that has both quick-acting and slow-release humic acid. Even the combination of humic acid and potassium ions (K+) is more reliable than humic acid and ammonium ions (NH4+). Potassium humate has good water solubility and will not limit the absorption of plants, but will only make the fertilizer effect longer. Relevant studies have shown that humic acid can increase the potassium uptake of crops by more than 30% and increase production by more than 12%.
