| We spread 10's of thousands of tons of gypsum each year, and if I understand what you what you are asking, gypsum is unlikely to help. Gypsum will help with water infiltration if the soil seals off (usually this means a high clay content). Gypsum and water will drive salt in the soil down out of the root zone. Gypsum is a fairly cheap source of calcium and sulfate, and does not have a significant effect on the soil PH. If you need to increase the soils moisture holding ability, the suggestion to add manure or organic matter is what I would try. A soils lab like A & L is the first place I would call. | |

Anyone using gypsum?
