AVAIL T5 is a patented fertilizer enhancer based on Verdesian’s new T5 polymer technology used to treat granular or liquid P fertilizers. Verdesian’s polymers are engineered, soluble macromolecules composed of highly active, negatively charged repeating subunits that complex and increase the solubility of plant nutrients. AVAIL T5 has a negative charge that provides the material with a high cation exchange capacity (CEC), about 4x that of humic acids!
