Abstract

Helicopters may prove the best method of applying sulfur fertilizer on rangeland too steep for ground application, or with no nearby landing strip for fixed-wing aircraft. Helicopter fertilization of 457 acres of the San Joaquin Experimental Range in central California in 1960 and 1963 was fast and practical.
