Certainly, here’s an article on the recommendation rate of zinc sulfate in cotton crop:
Zinc is an essential micronutrient that plays a crucial role in the growth and development of plants. Cotton crops require adequate zinc for proper growth, yield, and quality. Zinc sulfate is a commonly used fertilizer to meet the zinc requirements of cotton crops. But, what is the recommendation rate of zinc sulfate for cotton crops?
According to the University of Georgia’s Extension, the recommended rate of zinc sulfate for cotton varies depending on the soil type and plant growth stage. For sandy soils, the recommended rate is 10-20 lbs per acre, whereas for clay soils, it is 20-30 lbs per acre. It is important to note that these recommendations are based on the assumption of 35% zinc content in zinc sulfate.
The application of zinc sulfate should be done during the pre-planting stage or as a side dressing during the early growth stage of the cotton plant. It is recommended to apply zinc sulfate in combination with other fertilizers, mainly nitrogen, phosphorus, and potassium, to maximize growth and yield.
The benefits of applying zinc sulfate in cotton crops are numerous. Zinc plays a critical role in the production of chlorophyll, which is essential for photosynthesis. It also activates various enzymes involved in plant growth and development. Zinc plays a significant role in the formation of cotton fibers, which affects the quality of cotton.
In conclusion, the recommendation rate of zinc sulfate varies depending on the soil type and plant growth stage. Applying zinc sulfate during the early growth stage of cotton in combination with other fertilizers is recommended for optimal growth, yield, and quality of cotton. Adequate zinc supply to cotton plants also improves the plant’s resistance to diseases and other stress factors. It is essential to monitor the soil nutrient levels regularly and adjust the fertilizer application accordingly to ensure the proper growth of cotton crops.
