Agricultural Gypsum

Agricultural Gypsum is specified by its material basis (Ca + S), commercial form (powder) and intended application. Compare declared Ca / Mg / S basis; particle size and moisture; reactivity / neutralizing value where relevant before agreeing a grade. A family name or photograph is not a substitute for the batch analysis and destination-specific acceptance limits. Agricultural Gypsum — Secondary nutrients and soil amendments. Declare nutrient basis, chemical form, solubility and applicable destination registration. N-P-K grades use N, P2O5 and K2O; oxide reporting is not elemental P or K.

Product-specific COA, SDS where applicable, origin, inspection, packaging and transport documentation; issued for the agreed grade and lot. Parameters to agree: declared Ca / Mg / S basis; particle size and moisture; reactivity / neutralizing value where relevant.
