If your plants are suffering from heavy, waterlogged, and sodic soils your solution: Diamond K Premium 97 Solution Grade Gypsum. Incorporating Gypsum, a form of Calcium Sulfate, into your soil fertility management program can quickly improve the structure of clay-bound soils and encourage sustainability of irrigated fields. Soil conditioners such as Gypsum are among the best-known in assisting growers and farmers to improve soil structure. This organic fertilizer contains ample amounts of Calcium (22.5%) and Sulfur (18.0%) in a 200 mesh solution grade formula. Gypsum penetrates deep in the soil layers improving soil structure, fruit quality, and the effectiveness of other organic inputs. If you are looking to improve your soil structure and drainage while eliminating the toxic effect of aluminum or salts, it is paramount that you incorporate Gypsum into your soil amendment plans. Calcium will help improve soil structure and create oxygen conditions essential to improve the soil and, in turn, the health of plants. Soils filled with proper oxygen increase crops' quality, leading to increased yields.

I have a greenhouse that unfortunately does not get the ideal sunlight due to its location on the north side of my home. I have been using Rocky Mountain BioAg’s Quantum Growth Organic Total for over a year and have seen a dramatic increase in plant growth and vegetable yield compared to past years. Highly recommend the product.
