The method of self-made potash with plant ash

The chemical formula of plant ash is K2CO3. Plant ash fertilizer contains almost all mineral elements contained in plant ash because it is the ash of plants after burning. In general, the content of potassium oxide in plant ash is relatively high, with an average of 10 kg of plant ash equivalent to 1 kg of potassium sulfate. Therefore, the self-made potash fertilizer is mainly based on plant ash. Benefits of self-made potash with plant ash: plant ash is suitable for potassium-loving crops, such as broad bean, potato, edamame bean, sweet potato and so on. Plant ash can also be used as a cover for rice seedling fields or vegetable seedbeds to keep warm, so as to increase ground temperature, reduce rotten rice seedlings, loosen topsoil and facilitate seedling pulling. Plant ash can be used as base fertilizer and topdressing, and those used as topdressing can be sprinkled on the leaves during the crop growing period, with a general dosage of 50kg / mu. Mix with 2-3 times wet soil before application to avoid being blown by the strong wind. Precautions for self-made potash plant ash: to accumulate and store plant ash, it is best to establish a permanent ash warehouse to prevent the loss of nutrients caused by wind or rain. Because plant ash belongs to alkaline fertilizer, it can not be mixed with ammonium nitrogen fertilizer such as ammonium sulfate and ammonium nitrate. At the same time, it should not be mixed with human feces and livestock feces, so as not to cause the volatilization loss of ammonium nitrogen.
