Sulfur (S) deficiency shows on small corn plants as a general yellowing of the foliage, similar to nitrogen deficiency. Treatments for sulfur deficiency include gypsum, manure, ammonium sulfate, Thiosulfate, and elemental sulfur. Manure application is an important source of sulfur for crops in many areas. Sulfur deficiency affects the youngest, upper leaves of most crops first, before progressing to older, lower plant tissues. In potting soil, a sulphur deficiency can occur when the pH is too high, or too much calcium is present. Elemental sulfur can be added to fertilizer mixes. However, sandy soil need more frequent application of sulfur, since the sulfur is more likely to leach away in heavy rain. Though sulfur is often considered a secondary macronutrient, only nitrogen, phosphorus and potassium rank higher in the quantity required for healthy crops and increased yields. Unlike most other deficiencies that cause yellowing of the leaves, a sulfur deficiency will start at the back of the leaf and move it’s way forward as opposed to starting at the tips. Just real, knowledgeable people ready to help. Frequent rainfall can also affect the amount of available sulfur, moving it further down into the soil, where it becomes inaccessible to many plants, particularly young plants with small, shallow root systems.

Sulfur is most available to plants when the pH of the soil is 6 or more though most plants should be able to uptake sufficient sulfur if the soil pH is 5.5 or higher. Sulfur is needed in fairly large quantities by most crops. Once an abundant nutrient in the soil, the amount of sulfur available for crops has declined in recent years, making sulfur deficiency much more common.
