Organic Soil Sulfur To Lower Soil pH & Supply Sulfur Concentrated source lowers pH faster than any other soil amendment. Easy-to-spread, dust-free formulation contains 90% sulfur with 10% bentonite as a binder. As the bentonite absorbs moisture from the soil, the granules swell and break apart, releasing the sulfur particles. (Not a mined sulfur.) Use at rates of 1-5 lb/100 sq ft or 200-2000 lb/acre. Proper rates should be determined by a soil analysis. A little sulfur is a stimulant to soil microlife, an overdose is toxic. Use care during application, some are sulfur-sensitive.
