The effect of grass ash is good. The ash contains various potassium salts, of which potassium carbonate is the main, followed by potassium sulphate and a small amount of potassium chloride. It is a physiological alkaline fertilizer. Therefore, the ash can not be mixed with ammonium nitrogen. Can not be mixed with organic manure such as human excrement and manure. In order to improve the efficiency of ash and ash, it is necessary to carry out single-single sputum and apply alone. Grass ash can be used as base fertilizer, seed fertilizer and top dressing, and its aqueous solution can also be used for top dressing. It is advisable to use grass ash for concentrated application, and it can be applied by strips and acupoints. The depth is 8-10 cm, and the soil is covered after application. Mix 2 to 3 times of wet soil before application or spray it with a little water to prevent ash from flying. The amount of grass ash is limited, and it should first be applied to the potassium-deficient soil in order to give full play to the fertilizer effect of the ash. Generally speaking, the sandy soil with coarse soil texture is mostly potassium-deficient soil, and the effect is very obvious after applying the ash. Secondly, it is preferentially applied to crops with potassium, such as potatoes, sweet potatoes, cotton, and legumes. The annual acre is generally 30-50 kg.
