Contributions of atmospheric sulfur (S) to soil fertility at 15 locations in South Carolina were estimated during the 5-year period 1973–77 by measuring the S content of precipitation samples accumulated at 30-day intervals and by measuring the S collected in lead peroxide samplers exposed to the air at the same time intervals. The S content of precipitation was compared with similar data collected at three locations in 1953–55. Concurrently with the 1973–77 study, long-term uniform field experiments designed to measure response of seven crops to S added in the fertilizer were conducted at selected locations. The mean estimated annual amount of S added to the soil in precipitation for the period 1973–75 was 11.3 kg per ha. The corresponding addition in 1953–55 was 6.3 kg/ha. The mean estimated amount of S added to the soil from the air and precipitation increased from 11.2 kg/ha in 1973 to 19.8 kg/ha in 1977. Sulfur added in the fertilizer resulted in an increased yield (10% probability level) for one crop at one location.
