Balanced fertilizer is a common name for products with the same content of nitrogen, phosphorus and potassium, such as npk15-15-15, npk18-18-18, npk20-20, etc. It is different from high nitrogen and high potassium products

Balanced fertilization is to select the best fertilization method according to the scientific proportion and quantity of organic fertilizer, NPK and trace elements according to the characteristics of crop fertilizer demand, the status of soil nutrient content and the requirements of target yield. It mainly includes the following steps:

Soil testing: through the analysis and measurement of soil nutrients, we can accurately grasp the soil nutrient status and fertilizer supply performance, so as to provide a scientific basis for balanced fertilization.

Fertilizer matching: formula is the key to fertilization. On the basis of soil testing, according to the soil characteristics, cultivation habits, fertilizer requirements of crops, production level, climate and other conditions, combined with the previous year's yield level, the target yield is determined, and then according to the effect of fertilizer, the most suitable amount and the best proportion of nitrogen, phosphorus and potassium are proposed.

Fertilizer supply: select high-quality single fertilizer or special fertilizer, compound fertilizer, organic-inorganic compound fertilizer and other fertilizer varieties for scientific matching according to the formula requirements.

Application: according to the soil type, the growth characteristics of crops and the law of fertilizer demand, formulate the corresponding fertilization mode.
