Factors leading to sulfur deficiency, soil and water tests, soil test interpretation and fertilizer materials that contain sulfur are covered here.
Sulfur, one of the macro-nutrients, may be deficient in some sandy soils but usually is plentiful in other soils of the state. The amounts contained by healthy crops are on the same order as phosphorus, ranging from 0.2 percent to .5 percent sulfur. It is a component of certain amino acids, and so is part of several proteins essential for plants and animals.
