Spring plow fertilizer mixed with seven not

1. Fertilizer should not be mixed with rhizobia fertilizer and other bacterial fertilizers. Because chemical fertilizers have strong corrosiveness, volatility, and water absorption, if they are used in combination with bacterial fertilizers, they will kill or inhibit viable bacteria and make the fertilizer useless.

2. Ammonia should not be mixed with human waste, grass ash, potash, ammonium phosphate, potassium chloride, urea, and ammonium bicarbonate. Ammonium bicarbonate must not be mixed with plant ash, human waste, and potash nitrogen. Ammonium sulfate cannot be mixed with ash and ammonium bicarbonate. Ammonium nitrate cannot be mixed with grass ash, ammonia, etc. If the fertilizer mentioned above is mixed and applied, it will cause acid-base neutralization reaction and reduce the fertilizer effect.

3. Phosphate rock, bone powder and other insoluble phosphate fertilizers should not be mixed with alkaline fertilizers such as grass ash, lime ammonia, and lime. Otherwise it will neutralize the organic acids in the soil, making it harder to dissolve insoluble phosphate fertilizers, and crops cannot absorb and use them.

4. Alkaline fertilizers such as calcium magnesium phosphate do not mix with ammonium ammonia fertilizers. Because alkaline fertilizers and ammonium ammonia fertilizers such as ammonium sulfate, ammonium bicarbonate, ammonium chloride, etc., will lead to and increase the volatilization loss of ammonia, reducing fertilizer efficiency.

5. Manure, urine, and other farmyard fertilizers should not be mixed with calcium, magnesium phosphate, grass ash, lime, and other alkaline fertilizers. Because the main component of human and animal urine is nitrogen, if it is mixed with a strong alkaline fertilizer, it will neutralize and fail.

6. Do not mix superphosphate with grass ash, lime nitrogen, lime and other alkaline fertilizers. Because calcium superphosphate contains free acid, which is acidic, and the alkaline fertilizer contains more calcium, if the two are mixed, it will cause acid-base reaction, reduce the fertilizer efficiency, and it will cause calcium to fix the phosphorus, resulting in "two loses." .

7. Do not mix urea with carbon ammonia. Since urea is applied to the soil, it must be converted into ammonia before it can be absorbed by the crop. The conversion rate is much slower under alkaline conditions than under acidic conditions. After the carbon ammonia was applied to the soil, the reaction was alkaline and the pH was 8.2-8.4. Mixed use of carbon and ammonia in farmland can greatly reduce the rate of conversion of urea to ammonia, which can easily lead to loss of urea and loss of volatiles. Therefore, urea and carbon ammonia should not be mixed or applied at the same time.
