Thus, S deficiency may occur more frequently with large amounts of crop residue early in the growing season. Sulfur deficiencies are becoming increasingly common due to reduced inputs of sulfur from atmospheric deposition, as well as changes in agricultural practices and growth of high-yield crops. It is easier for the plant to take up sulphate at a lower pH level. Sometimes an unhealthy plant is suffering from a nutrient deficiency or even too much of any one nutrient. Investigations determined the growth issues were largely due to S deficiency, with the most prominent symptoms in field areas with low soil organic matter and side-slope landscape position.
