What are the characteristics of ammonium bicarbonate? What effects does applying ammonium bicarbonate have? Why is the effect good when used in spring? Experienced netizens are also asked to give a brief introduction.1. Fast fertilizer effect: Compared with urea, ammonium bicarbonate differs in that urea cannot be directly absorbed by crops after being applied to the soil, and under suitable conditions it still needs to undergo a series of transformations before it can be absorbed by crops, so the fertilization effect is slower. After ammonium bicarbonate is applied to the soil, it is immediately adsorbed by the soil colloids and directly supplied for absorption and use by crops, taking effect the same day.
2. Multiple absorption: After ammonium bicarbonate is applied to the soil, it forms ammonia and carbon dioxide. The ammonia is used by crop roots; the carbon dioxide is directly absorbed by crops as a gas fertilizer.
3. Pest repellence and sterilization: When ammonium bicarbonate is applied, pests in the soil can be quickly killed or driven away, and harmful bacteria can also be poisoned and killed, achieving the goal of crops being free from disease and pest damage.
4. High cost-effectiveness: Compared with other nitrogen fertilizers with the same fertilizer effect, ammonium bicarbonate is more economical and affordable, and after being absorbed by crops, ammonium bicarbonate leaves no residue and will not cause any harm to the soil.
Zhongdiwang suggests that in the early spring season, when the soil thaws and crops need fertilizer as they revive in spring (needing to absorb a large amount of nitrogen fertilizer in time), this completely matches the unique characteristics of ammonium bicarbonate. Therefore, it is recommended to apply ammonium bicarbonate in spring, using the method of burying the fertilizer.
