How much fertilizer is needed for cotton
Cotton is a highly nutritious crop, but it also demands significant amounts of fertilizer and requires advanced fertilization techniques. According to research, for every 100 kilograms of lint produced, the plant needs approximately 10 to 18.5 kilograms of nitrogen, 3.5 to 6 kilograms of phosphorus (Pâ‚‚Oâ‚…), and 13 to 16.5 kilograms of potassium (Kâ‚‚O). The ideal ratio of nitrogen, phosphorus, and potassium is roughly 3:1:3. In addition to these major nutrients, cotton also absorbs 1.29 kilograms of magnesium and 1.86 kilograms of sulfur per 100 kilograms of seed cotton. For every tonne of dry matter formed, cotton requires 106 grams of iron, 15 grams of boron, 14 grams of manganese, 16 grams of zinc, and just 0.77 grams of molybdenum. These essential nutrients play a crucial role in ensuring healthy growth, strong fiber development, and high yield. Proper nutrient management is therefore vital for maximizing cotton production while maintaining soil fertility and environmental sustainability. Farmers must carefully plan their fertilization strategies based on soil tests, crop stage, and local conditions to achieve optimal results.
