Details

description2

GROWMAX-Mn is a high-efficiency chelated manganese fertilizer formulated with advanced EDTA chelation technology, which prevents manganese from being fixed by soil and avoids antagonistic reactions with other nutrients. This ensures crops can efficiently absorb and utilize manganese, maintaining a stable supply for healthy growth.The product promotes chloroplast formation, alleviates leaf chlorosis, and extends the functional period of leaves, enhancing photosynthetic efficiency and overall crop vigor. Water-soluble small molecules allow rapid manganese absorption and utilization, minimizing nutrient waste. GROWMAX-Mn also improves nitrogen, calcium, and iron uptake, boosts disease resistance, and contributes to increased grain weight, better vitamin content, and improved taste and appearance of crops.
