The commonly used potassium fertilizers for fruit tree production include potassium sulfate, potassium chloride, cellar ash potassium, and grass ash.
Potassium sulphate contains 50%-52% of active ingredient, which is a good potash suitable for various fruit trees. It can be used as base fertilizer and top dressing.
Potassium chloride active ingredient content is generally 50-60%, is a physiological acidic fertilizer, can be used as base fertilizer, top dressing and top dressing. In coastal areas, it is necessary to avoid the use of Fuji, Red Star and other varieties susceptible to manganese damage (Apple rough skin disease).
Potash potash is a by-product of the cement industry. Different cement manufacturers, potash ash potash potassium content is not the same, the content is low about 8%, high up to 20%. Potash ash potash also contains calcium, magnesium, sulfur, iron and other trace elements, and it is an alkaline potash that can be used as base fertilizer and top dressing. It is especially suitable for application in acidic and slightly acidic soils. Can not be mixed with ammonium nitrogen fertilizer, superphosphate, so as to avoid loss of ammonium nitrogen and reduce the effectiveness of phosphorus.
Ash contains a variety of ash elements, such as potassium, calcium, magnesium, sulfur, iron, silicon and so on. Among them, potassium, calcium, phosphorus followed. The woodgrass ash contains K2O8.09%, P2O52.3%, and CaO10.72%. Grass ash can be used as base fertilizer and top dressing. The best effect of application in early spring can not only meet the needs of growth and development of fruit trees, but also increase the temperature of the soil and promote root growth. The plant ash is alkaline and can not be mixed with ammonium nitrogen fertilizer to prevent evaporation of ammonia.
