How to use plant ash?

What nutrients does plant ash contain? What are the characteristics of plant ash? What do you need to pay attention to when applying plant ash? The following farming help planting network is briefly introduced for netizens' reference. In rural areas, straw and firewood of all kinds of crops are used as fuel, and the ash after burning is called plant ash. This is the main source of potash fertilizer in rural areas, which can be used not only as base fertilizer for crops such as sweet potato and wheat, but also as seed fertilizer on beans. The composition of plant ash is very complex, and the ash elements in plants are all found in plant ash, such as phosphorus, potassium, calcium, magnesium and sulfur, of which potassium, phosphorus and calcium are more abundant, generally containing 5% and 10% potassium. No matter which kind of plant ash, the potassium is soluble, quick-acting, and can be directly absorbed by crops. Plant ash is a kind of alkaline fertilizer. In the process of use and preservation, we should pay attention to the following four points: 1. Plant ash is an alkaline fertilizer and should not be mixed with ammonium sulfate and ammonium nitrate. Ammonium sulfate, ammonium nitrate and ammonium bicarbonate are all ammonium nitrogen fertilizers. If they are mixed with plant ash, the nitrogen in the nitrogen fertilizer will turn into ammonia and run away. When plant ash is used at the same time as acid fertilizer, we must be careful not to mix them together. 2. Plant ash should not be mixed with human feces and livestock feces. It is wrong for rural areas to pour plant ash into pits or pig pens for storage. Livestock feces and human feces and urine are a kind of late-acting acidic nitrogen fertilizer, such as pouring alkaline plant ash into acidic livestock feces and urine, neutralizing ammonia to volatilize ammonia, thus reducing fertilizer efficiency. The mixture of plant ash and livestock feces and urine for 1 week could lose more than half of the ammonium nitrogen in feces and urine, and the longer the mixing time, the more nitrogen loss. 3. The nutrients in plant ash are easily soluble in water. In order to preserve the ash, it should be stored separately in places such as ash storehouses or sheds to protect them from wind and rain. After the rain, the ash, potassium will suffer serious loss. 4. Plant ash can not be mixed with calcium superphosphate, which will reduce the availability of phosphorus.
