Can gypsum be used to improve poor soils?
Gypsum is chemically known as calcium sulfate and this has been used on soils for a very long time to provide both plant nutrients and to improve the structure of certain problem soils. As a nutrient supply, gypsum is a good source of calcium and is frequently used instead of limestone when the pH of the soil is in a good range for plant growth and no further correction is needed. Unlike lime, gypsum will not affect the soil pH. It is also a good source of sulfur and can be used instead of elemental sulfur for correcting soil deficiencies.
