Cal-Sul Greens Grade

Cal-Sul is a micro-sized (90 SGN) single-nutrient fertilizer. Source of calcium and sulfur for plant nutrition when plants are becoming more deficient for sulfur and the soil is not supplying enough. Improves acid soils and treats aluminum toxicity.

One of gypsum’s main advantages is its ability to reduce aluminum toxicity, which often accompanies soil acidity, particularly in sub-soils. Gypsum can improve some acid soils even beyond what lime can do for them, which makes it possible to have deeper rooting with resulting benefits to the crops. Improves soil structure, flocculation, or aggregation, which is needed to give favourable soil structure for root growth and air and water movement. Improves water infiltration. Gypsum also improves the ability of soil to drain and not become waterlogged due to a combination of high sodium, swelling clay and excess water.
