Its main component is potassium carbonate, and it is rich in phosphorus, potassium, calcium, magnesium, iron and other elements. It is a natural quick-acting potassium fertilizer. It can promote the photosynthesis of plants and improve the quality of crops. Because its main component is potassium carbonate, it is an alkaline fertilizer, which can also neutralize acidic soil to a certain extent and has bactericidal effect on plant roots. But plant ash is not suitable for some alkaline soils. Plant ash can also be used as an insecticide after being filtered with water, which has a good killing effect on red spiders and aphids.
I still remember living in the countryside when I was a child. When I grow vegetables at home, I will pick some plant ash from home and bury it in the ground. At that time, not a lot of chemical fertilizers were used, but farmyard manure was used. But when using it, we should also pay attention not to overdo it, otherwise it is likely to destroy the acidity and alkalinity of the land.
In fact, chemical knowledge is everywhere in life. It is much more convenient to grow vegetables and land now. You don't need to make your own plant ash, just buy fertilizer. Plant ash plays a great role, of course, poultry manure is also used as fertilizer in rural areas.
This is what Bian Xiao knows. I wonder if you have any other knowledge about plant ash. High school chemistry often encounters such problems. At that time, listening to the teacher's knowledge about plant ash, I only knew that acid land could be improved, but I didn't know it was so useful. Seeing this, I believe you must have a profound understanding of plant ash. If you live in the countryside, you can try using plant ash as fertilizer yourself. The vegetables grown in this way are really pure natural and pollution-free!
