STRUCTURE 7-21-0 5 GAL PGH Used at higher concentrations inSTRUCTURE 7 21 0 5 GAL ACTAGRO, Structure (7 21 0 with 0. 2% Zinc) is specially engineered as a significantly more mobile, efficient, and available form of soil applied phosphate. Replicated trials over many years have consistently shown that Structure creates a positive growth response in plants, resulting in increasing yields with less phosphate being applied. Structure contains nitrogen, phosphate, and zinc. This combination of nitrogen, phosphate,
