The Increasing Need For Supplemental Sulfur

The first occurrences of sulfur (S) deficiency in corn were reported in the 1960s. At the time, sulfur deficiency was virtually unheard of. Textbooks devoted chapters to nitrogen (N), phosphorus (P) and potassium (K) and their roles in crop production. Sulfur received only short paragraphs.

Soil Fertility and Compaction

Plant experts often say that high yields of good quality crops don’t result from any one factor (such as fertilizer application, or planting the best variety), but to a whole set of effective management inputs, generally defined as “best management practices.” Keeping the importance of best management practices top of mind, it’s instructive to consider the interactions of soil fertility and soil compaction in affecting plant growth.

Sulfur Nutrition of Cotton

Sulfur is an essential component of two amino acids, methionine and cysteine. These amino acids are key building blocks needed for protein formation in the cotton plant. Research studies indicate that high-yielding cotton will take up nearly 40 pounds of S during the growing season. That’s about the same amount as magnesium (Mg) and about two-thirds of the phosphorus (P) needed for developing cotton roots, stems, leaves and bolls. A shortage of S can also trigger inefficient plant use of nitrogen (N), since both are required for protein development.

Potassium Magnesium Sulfate: Langbeinite

Langbeinite is a unique source of plant nutrition, since three essential nutrients combine naturally into one mineral. It provides a readily available supply of Potassium (K), Magnesium (Mg) and Sulfur (S) to growing plants.

Sulfate Sulfur vs. Elemental Sulfur Part I: There’s a Difference

- Sulfate-Sulfur is the only form of S the plant can utilize.
- Elemental S is dependent upon time, temperature and moisture to be available to the plant.
- Sulfate-Sulfur will not acidify the soil.

For various reasons, sulfur (S) deficiencies are increasing in many areas of the country. Consequently, fertility programs use this nutrient more routinely. The most common chemical forms of S used in fertilizers are sulfate S (SO₄²⁻) and elemental S (S⁰). But these two forms of S react quite differently in soils. It’s very important to understand the differences between SO₄²⁻ and S⁰ in order to use these two forms in the most effective manner possible.
