Agricultural Prilled Sulfur..........99.5% (elemental)

We sell and deliver agricultural Sulfur as an organic soil amendment and soil conditioner by the truckload throughout central and northern California.

Actually, soils get sulfur from three sources: airborne particles, the weathering of minerals in soils, and microbial activity. Sulfur conversion by microbes happens in soil containing large amounts of decomposing organic materials like green manures, animal wastes (including urine), insects, worms, and dead microbes. Grass clippings contain atmospheric sulfur and should also be added back to the soil. Some soil sulfur occurs naturally from the weathering process of minerals.
