AB Soil applications of granular sulfur were effective in reducing or eliminating the chlorosis of pin oaks growing on an alkaline heavy clay soil. Granular sulfur at rates of 6 to 10 lbs./100 sq. ft. increased the availability of iron and manganese after 3 to 6 months and in some cases, levels of these two elements remained in the desirable range 10 years after the initial treatment. Soil applications of granular sulfur influences the cause of chlorosis, not just the symptom, and does not injure the plant.
