About Gypsum Rock Dust
Limestone has been used more extensively for adding soil fertility than any other type throughout modern agricultural history. Gypsum is a limestone that is comprised primarily of calcium and sulphur. Around the world large deposits of these sedimentary stones can be found. They are the result of ancient sea life that incorporated calcium into their shells mixed with sulphuric water conditions.
Gypsum can be especially helpful in areas that were predominately grassland or for adding sulphur due to crop demands. Sulphur is especially important for quality factors such as sugar content and flavors in food.
