Cotton requires different nutrient supplies at different growth stages, so different types and proportions of fertilizers are required at different growth stages. The following are fertilizer recommendations for cotton during various growth stages:
Seed germination stage and seedling stage: At this stage, cotton has a greater demand for nitrogen fertilizer, and an appropriate amount of nitrogen fertilizer can be applied to promote the growth of seedlings. Some phosphate fertilizer can also be applied at this time to help the growth and development of the root system.
Flower bud differentiation and flowering stages: This stage is a critical period for cotton growth and development. Sufficient nitrogen and phosphorus fertilizers are needed to promote flower bud differentiation and flowering. An appropriate amount of potassium fertilizer can also be applied at this time to help improve the quality of cotton fiber.
Boll-bearing and fruit-expansion period and fiber growth period: During this stage, cotton requires a large amount of nitrogen and potassium fertilizers to promote fiber growth and development. An appropriate amount of phosphate fertilizer can also be applied at this time to help improve the quality of cotton fiber.

Seed maturation and harvesting stages: At this stage, appropriate amounts of phosphorus and potassium fertilizers can be applied to promote the development and maturity of cottonseeds and improve the yield and quality of cottonseeds. |  |
When fertilizing, it is necessary to determine the appropriate fertilizer type and application amount based on the soil nutrient status and cotton growth conditions to avoid excessive or insufficient fertilization. At the same time, reasonable fertilization can improve the yield and quality of cotton and promote the healthy growth of cotton.
