The main component of grass ash is potassium carbonate, of which the most abundant is potassium element, generally containing potassium 6 to 12%, of which more than 90% is water-soluble and exists in the form of carbonate; followed by phosphorus, generally containing 1.5 to 3%; it also contains calcium, magnesium, silica, sulfur and iron, manganese, copper, zinc, boron, molybdenum and other micro-nutrients.
The ash of different plants has different nutrient contents, and the potassium content of sunflower straw is the highest. When applying grass ash in equal potassium amount, the fertilizing effect is better than chemical potash fertilizer. Anhydrous material is white granular powder, crystalline product is white translucent small crystals or particles, odorless, with strong alkaline taste, it is a kind of inorganic agricultural fertilizer with wide source, low cost, complete nutrients and obvious fertilizer effect.
Extended information:

3, to prevent defoliation Spray 10% grass ash leachate as a supplemental nutrient, can improve leaf vitality, prevent early defoliation, enhance photosynthesis, and promote the flowers and fruits beautiful and colorful.
4, as a disinfectant: grass ash is a widely available disinfectant raw materials in rural areas, with a strong role in killing pathogenic bacteria and viruses, its effect is similar to the commonly used strong disinfectant caustic soda.
5, to promote rooting: in the transplanting of seedlings, with grass ash with organic fertilizer as a base fertilizer, not only can increase the effective nutrients of the base fertilizer and nutrient soil, to promote the growth of the root system, but also to alleviate the role of pests and diseases.
