Potassium-rich WSF fortified with calcium and sulfur for fruit initiation and development. High potassium drives rapid sugar translocation from source to sink, maximizing fruit size, weight, and market quality. Calcium enhances firmness and post-harvest shelf life; sulfur activates key metabolic pathways for higher yields. Synergify™ technology ensures superior amino acid mediated nutrient delivery, while built-in nitrification inhibitors keep nitrogen synchronized with crop demand for peak NUE.
