Greenway Biotech Gypsum Powder

Gypsum works by displacing sodium particles in clay soil, which helps the soil particles clump together into larger aggregates. This process improves the soil's structure, allowing for better water drainage, increased aeration, and easier root penetration.

Gypsum is generally pH-neutral, so it won't significantly lower the pH of your soil like elemental sulfur would. Instead, it is best used to neutralize alkaline soils by addressing sodic conditions and providing calcium to balance soil chemistry.

Yes, this is a natural mineral compound that is safe for vegetable gardens. It provides essential calcium and sulfur, which are vital nutrients for many crops, and helps create a healthier environment for beneficial soil organisms like earthworms.

Because it is 100% water-soluble, you can easily mix it into a watering can or sprayer for liquid application, which allows for faster absorption into the soil. Alternatively, you can broadcast the dry powder over the soil surface and water it in thoroughly.

Gypsum provides a direct boost of calcium and sulfur without altering the nitrogen, phosphorus, or potassium levels of your fertilizer. It is an excellent supplement if your soil test indicates a calcium deficiency or if you need to improve soil structure without changing the NPK balance.
