Ammonium bicarbonate is a traditional fertilizer and is still loved by farmers' friends. The advantage of ammonium bicarbonate is that it is absorbed and utilized quickly by crops.
Compared with urea, urea can not be directly absorbed by crops after being applied to the soil quickly. Under the condition of condition, a series of transformations must be carried out in order to be absorbed by the crops, and the fertilization effect is later. After being applied to the soil, ammonium bicarbonate is adsorbed by the soil colloid and directly used for crop absorption and utilization.
After the double-effect ammonium bicarbonate is applied to the soil, ammonia and carbon dioxide are formed, and the ammonia is utilized by the crop roots; carbon dioxide is directly absorbed by the crop as a gas fertilizer.
Deworming, bactericidal application of ammonium bicarbonate, pests in the soil can be quickly killed or driven away, and can kill harmful bacteria, to achieve the purpose of crops without pests and diseases.
Compared with other fertilizers with the same fertilizer efficiency, the cost-effective ammonium carbonate is more economical, and the ammonium bicarbonate is absorbed by the crop without residue and does not cause any harm to the soil.
In spring, the soil is frozen, and the fertilizer requirements of the crop are exactly the same as those of ammonium bicarbonate. Therefore, ammonium bicarbonate is the best choice at this time.
