Which fertilizers are suitable for foliar dressing
Foliar fertilizers, also known as leaf fertilizers or foliar nutrient solutions, are specially formulated to be applied directly onto plant leaves. These fertilizers are designed to provide essential nutrients quickly and efficiently, bypassing the root system. Depending on their composition, they can be categorized into several types, such as nitrogen-based fertilizers, phosphate fertilizers, potash fertilizers, compound fertilizers containing both phosphorus and potassium, NPK fertilizers, micronutrient fertilizers, rare earth fertilizers, and those combined with plant growth regulators.
Commonly used foliar fertilizers for vegetables include urea, potassium sulfate, superphosphate, potassium dihydrogen phosphate, borax, ammonium molybdate, zinc sulfate, rice vinegar, sucrose, rare earth microelement fertilizers, and ash leaching solutions. These products are generally stable and less likely to cause leaf burn when applied correctly. They offer a quick way to supplement nutrients, especially during critical growth stages or in cases of nutrient deficiency. Proper application methods and dilution ratios are important to ensure effectiveness and avoid any potential damage to the plants. With careful use, foliar fertilization can significantly improve crop yield and quality.
