In addition, gypsum’s solubility promotes soil porosity which enhances water infiltration. Also, the application of gypsum enables fibrous root crops such as wheat and corn to root deeper and better absorb nutrients.However, for precise calculations, a soil test and consultation with an agricultural expert are recommended. What is the application rate for gypsum in clay soil? For clay soils, a general application rate is about 40 to 50 pounds of gypsum per 1,000 square feet. Again, it’s important to conduct a soil test for more accurate recommendations. Success in reclaiming non-irrigated sodic or saline-sodic soils with gypsum application may be possible on coarse textured soils that receive precipitation in excess of soil water holding capacity. Remember: Adding sulfur products only makes sense when: a) a soil is sodic and has free lime present or, when; b) a soil is basic (high pH). Gypsum can help loosen clay soils and improve soil structure by transforming fine, tightly packed particles into larger clumps that make the soil more porous, allowing air, water and nutrients to penetrate the soil more easily. This also helps to encourage better root development, resulting in stronger, healthier plants. The Physics of Humic Acid. Humic acids are extremely important as a medium for transporting nutrients from the soil to the plant because they can hold onto ionized nutrients, preventing them from leaching away. Humic acids are also attracted to the depletion zone of the plant root. When they arrive at the roots, they bring along water and ...Amending soil with FGD gypsum (50GR and 100 GR) significantly decreased the soil pH s (pH of soil water saturation paste) up to 1.09–1.22 (P > 0.05).Mar 8, 2018 · A common flaw in the analysis of soils containing gypsum involves drying samples at temperatures > 40°C.
