Organic Sulfur 90% (Granular) 50 lbs

This concentrated source of elemental sulfur lowers soil pH more quickly than any other amendment, making it ideal for correcting alkaline conditions in production fields. The dust-free granules contain 90% sulfur blended with bentonite clay. As the bentonite absorbs moisture, the particles swell, break apart, and release fine sulfur evenly through the soil profile. Unlike mined sulfur, this formulation provides consistent performance and reliable application.

For farmers, sulfur is more than just a soil acidifier—it is an essential nutrient that supports crop productivity. It is a critical component in amino acids and enzymes that drive protein synthesis, directly influencing crop yield and quality. By lowering pH, sulfur improves the availability of phosphorus, iron, and other micronutrients, ensuring plants can access the nutrition already present in the soil. Sulfur also enhances nitrogen efficiency, helping farmers get more value from their fertility programs.

Easy to spread and effective in a wide range of soils, this amendment gives growers a dependable tool to manage pH, balance fertility, and improve overall field performance.

• Proper rates should be determined by a soil analysis
• Use at rates of 1-5 lb/100 sq ft or 200-2000 lb/acre
• A little sulfur is a stimulant to soil micro-life, an overdose is toxic. Use care during application, some are sulfur-sensitive.
