Results of this three-year field test on a sandy Coastal Plain soil with low levels of organic matter and extractable SO_4-S in the surface 18 inches showed that cotton may require annual applications of 20 lb S/A to achieve high yields. These results also suggest that for lint production, differences among available commercial S fertilizer sources should be minimal. Sulfur should be applied to cotton preplant. However, in this test delaying application to first square was acceptable in two out of three years.
