Sulfur and Manganese Release from Soils Treated with Prilled Sulfur and Sulfur-Bentonite1
- D. L. Lindell and

Seven Nebraska soils were used to compare prilled sulfur and a sulfur-bentonite formulation in regard to the amount of sulfate-sulfur, manganese, and hydrogen released to a leaching solution after successive incubations. Also the effects of sulfur fertilizer granule concentrations in the soil were studied. Generally, the amount of sulfate-sulfur and manganese and the pH values in leachates from the columns containing sulfur-bentonite were not different from those from columns containing prilled sulfur. Differences among soils could not be explained on the basis of measured soil properties. The relationships between the amounts of sulfate-sulfur or manganese released and percentage sulfur or sulfur-bentonite in the soil were generally quadratic with the maximum release occurring in the range 30 to 60% sulfur. The greatest amount of sulfur released per gram sulfur added occurred at the lowest sulfur to soil ratio studied. (0.1).Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
