Yates Leaf Greener Copper Chelate is an easy-to-use liquid trace element. It corrects copper deficiency. Copper deficiency is indicated by yellowing of younger leaves and die-back of tips in young shoots. This deficiency is more common in sandy or acidic soils than in clay soils. Recommended as a foliar application, this delivers copper directly to the deficient leaves for faster results. Foliar applications also result in much lower copper additions into the soil when compared to traditional soil drench applications, resulting in less wastage and lower risk of soil toxicity.
