In order to facilitate the operation of cotton farmers, special fertilizer manufacturers for cotton production optimize the allocation of nitrogen, phosphorus, potassium and trace elements according to the needs of cotton growth and development. Cotton farmers can achieve scientific fertilization methods and fertilization according to their own production requirements. Intended purpose. With the goal of 100-125 kg of cotton per mu (leather), the organic matter content of cotton field is 1%~1.2%, and the organic fertilizer is 4000~5000 kg, 15 kg of pure nitrogen, 12 kg of pure phosphorus and 9 kg of pure potassium. Plus 1.2 kg of zinc sulfate and 0.5 to 1 kg of borax. If 75 kg of cotton (leather) is required per mu of cotton field, the organic matter of cotton field is required to be 0.8% to 1%, 7.5 kg of pure nitrogen, 6 kg of pure phosphorus, 4.5 kg of pure potassium, plus 0.5 g of zinc sulfate and borax. ~1 kg. In order to improve the effective utilization rate of fertilizer, cotton field fertilization should pay attention to the fertilization method. Generally, organic matter, phosphorus and potassium fertilizer, trace elements and 1/3 of nitrogen fertilizer should be mixed and applied as base fertilizer, combined with soil preparation for ditch application, and the remaining 2/3 nitrogen fertilizer. In combination with watering, top dressing is carried out during the cotton bud stage or early flowering stage.

Formulating fertilizer for cotton
Formulated fertilization of cotton, also known as balanced fertilization of cotton, is based on the characteristics of cotton growth and fertilizer requirements, according to the local soil nutrient status and the requirements of cotton production levels, different types and amounts of fertilizer are applied to make effective nutrients in the soil. It is in balance and meets the requirements for cotton fertilizer. Through the years of research and agricultural extension of agricultural research units, the ratio of nitrogen, phosphorus and potassium in cotton fields is generally 1:0.8:0.6. If zinc, boron and other trace elements can be applied as needed, the effect is even more good.
