Should You Use Gypsum for Soil?

How Does Gypsum Work in Soil? Gypsum may seem like a miracle solution for soil, if what you need is a miracle. If your clay soil is high in sodium and the sodium has replaced other minerals, like magnesium or calcium, the soil will separate or disperse into fine particles that stick to your boots and tools. Luckily, gypsum makes soil less sticky.
