Potassium nitrate compound fertilizer effect
1. Because it has no volatility, it can be directly applied to the soil surface.
2. Applying nitrate nitrogen to chloride-sensitive crops is more advantageous than ammonium nitrogen, such as citrus, grapes, vegetables, and other crops that are sensitive to chloride ions, because the nitrate nitrogen in potassium nitrate can prevent crops from absorbing chlorine in the soil. .
3. Nitrate nitrogen can quickly provide nutrients under any conditions, suitable for spring, summer, autumn and winter crops.
4. Will not cause salt accumulation in the soil.
How to use potassium nitrate compound fertilizer
1. Nitrate nitrogen can quickly provide nutrients under any conditions, suitable for crops in four seasons, and will not cause salt accumulation in the soil. It has no volatility and can be applied directly on the ground without covering. The ratio of nitrogen to potassium is about 1:3, which is suitable for most crops and is often used as a high-concentration potassium fertilizer.
2. Agricultural potassium nitrate has no chlorine and sodium, low salt index, good water solubility but no moisture absorption, high nutrient content, and rapid fertilizer effect. Potassium nitrate moves fast after entering the soil and is suitable for top dressing, but not for base fertilizer and seed fertilizer.
3. Potassium nitrate is suitable for dry fields and not for paddy fields. It can be sprayed as a foliar fertilizer. Seeds can be soaked, according to different crop seeds, the general concentration is about 1%.
4. Potassium nitrate is more suitable for crops that are sensitive to chloride ions, such as tobacco, citrus, grapes, and sugar beets. Nitrate nitrogen can be directly absorbed by crops, and it can also inhibit plants from absorbing other forms of nitrogen in the soil. Low salt index is more easily absorbed by roots.
