Sep 01, 1990 Calcite and elemental S did not influence yield or mineral content. Gypsum, as expected increased leaf S content, but leaf tissue S levels were not related to marketable yield. Slight decreases in soil pH due to increasing gypsum rate (0.5–4.3 t ha−1) were associated with changing accumulations of B, Mn, Fe, Ca, and Zn in the leaf tissue.

Hard water - Wikipedia
Hard water is water that has high mineral content (in contrast with "soft water"). Hard water is formed when water percolates through deposits of limestone, chalk or gypsum which are largely made up of calcium and magnesium carbonates, bicarbonates and sulfates.. Hard drinking water may have moderate health benefits. It can pose critical problems in industrial settings, where water hardness is ...
