Premium 97 Solution Grade Dimond Gypsum, excellent material to add for tomatoes and peppers. Gypsum can be used to improve soil structure, increase calcium and sulfur nutrients, and decrease salinity of your soil. Especially useful in clay-based soils.
Gypsum improves soil structure via flocculation. Calcium ions bind to clay particles, clumping the clay together to form larger soil aggregates. Larger aggregates prevent consolidation of your soil, which clay-based soils are prone to. Consolidation decreases the porosity of your soil. Low soil porosity is what prevents your plant's roots, and your fertilizer, from being able to penetrate deep into the soil.
Gypsum also supplies calcium and sulfur to your soil, which are nutrients essential to plant growth and development. The calcium in gypsum is also what decreases the salinity of your soil. Most soils are negatively charged, but sodium (the source of salinity) is positively charged. However, calcium is also positively charged. The calcium in the gypsum will displace the sodium bound to your soil particles, and the sodium will be leached away once your land is watered!
