EDTA-Mn features excellent water solubility, and it supports diversified application methods to match different farming scenarios. Foliar spraying is the most commonly used method for emergency correction of manganese deficiency. Nutrients can be absorbed directly through leaf cuticles, taking effect within a short period, which is perfect when yellowing and speckle symptoms are already observed on leaves. Drip irrigation and fertigation are suitable for large-scale farms and greenhouses. EDTA-Mn dissolves completely without residues, and it will not block drip tapes and micro-spray pipelines when added into irrigation water. It can also be mixed into base fertilizer for soil application to provide long-term manganese supply. Besides, it is a standard raw material for hydroponic nutrient solutions, substrate culture and seedling raising formulas, maintaining stable ion balance in the nutrient tank.
