Microelements are needed in trace quantities, but they are as important as NPK.
　　LEEF?Organic chelated Copper Fertilizer comes in granular form. The fertilizer have a slow-release property and chelation prevents the nutrients from being fixed by soil. Granular size is special design for using and providing uniform distribution of plant nutrients.The fertilizer can be used in bulk blending and for field application directly.
　　Specificion： Cu   12%
　　Size ： 2 - 4.5 mm， Dosage： 20 - 40 kg/ha.
　　Copper is required as a catalyst for the formation of chlorophyll. Copper deficiency was indentified as the cause of “mid crown chlorosis”, which results in reduced vegetative growth and very small fruit bunch yield. Copper is adsorbed and fixed by soil to be unavailable to be plant. Chelated Copper will help root tip absorb nutrients easily and also will help nutrients not to be tighten to the soil particle.
