Sulfur Plus is an organic soil acidifier that can help lower pH without over applying sulfur. It has a pH of about 3 and is finely milled to maximize soil contact. Because nutrient availability improves at a pH of 6.5 to 6.7, applying Sulfur Plus to lower pH soil can maximize fertilizer efficiency. Ideal for organic farmers, it meets National Organic Program (NOP) requirements for organic agriculture.
