Stoller’s SP Zinc EDTA Chelate is a micronutrient which is readily compatible with most products and can be used in replacement of Phenolic Chelate. It can be mixed with Roundup and most APP mixes.

Stoller’s SP Zinc EDTA Chelate is a highly efficient readily available chelated nutrient that will support your crop in producing greater yields, from seedling to top up applications mid-season through irrigation and foliar sprays. Stoller’s SP Zinc EDTA Chelate is also highly efficient at correcting crop deficiency’s quickly and efficiently and is ideal for maintenance application before deficiencies appear, in a normal program.   

Chelating agents such as EDTA chelate hold onto trace elements and stop them from binding to other elements-the end result is called a chelate. For more information read our brochure on using chelates to increase trace elements.

Backed by 40 years of research and field testing Stoller’s unique chelating technology enhances nutrient uptake, with a lower pH. The proven efficiency of Stoller’s own phenolic acid chelate ensures efficient absorption by plant roots, leaves and tissue with wide compatibility.

Stoller’s SP Zinc EDTA Chelate is compatible with a wide range of crops from Field & Greenhouse, Tree and Vine and Broadacres.
