Ammonium bicarbonate and urea can not be mixed with amide nitrogen in urea can not be absorbed by crops, only under the action of gland enzymes in soil, can be used by crops after conversion to ammonium nitrogen; carbon iron is applied to soil, causing short-term soil solution An acidic reaction accelerates the loss of nitrogen in the urea and cannot be mixed. Ammonium bicarbonate can not be mixed with bacterial fertilizer, because the former will emit a certain concentration of ammonia gas, which has a toxic effect on the latter's active bacteria, which will make the bacterial fertilizer lose its fertilizer effect.
Acidic fertilizer can not be mixed with alkaline fertilizers. Ammonium bicarbonate, ammonium sulfate, ammonium nitrate and ammonium phosphate cannot be mixed with alkaline fertilizers such as grass ash, lime, kiln ash and potassium fertilizer. Neutralization reaction will occur, causing nitrogen loss and reducing fertilizer efficiency.
Ammonium sulfate avoids long-term application of ammonium sulfate as a physiological acid fertilizer. Long-term application in the same soil will increase its acidity and destroy the aggregate structure. In alkaline soil, ammonium ions of ammonium sulfate are absorbed, while acid ions remain in the soil and calcium. A reaction occurs to harden the soil compaction.
