Sulfur’s Role in Soybean Success

Magnesium for Balanced Crop Nutrition

Magnesium (Mg) is one of three secondary macronutrients, along with calcium and sulfur, required for balanced crop nutrition. Often overlooked, Mg deficiencies can lead to reduced crop growth and yield.

Magnesium: Often Forgotten, but Most Essential

Without photosynthesis, plant life wouldn’t exist. And without magnesium (Mg), there would be no photosynthesis. Plants couldn’t produce our food, and hunger would become our No. 1 concern.

Sulfate Sulfur vs. Elemental Sulfur Part II: Characteristics of S Oxidation

The oxidation of elemental sulfur (S⁰) to sulfate sulfur (SO₄) in soil is a biological process and is carried out by several kinds of microorganisms. The rate at which this conversion takes place is determined by three main factors:

1. the microbiological population of the soil;
2. the physical properties of the S⁰ source; and
3. the environmental conditions in the soil.

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.

Maximize Yields and Sulfur Availability

Sulfur (S) is widely distributed throughout the world in many forms. Yet in some soils, insufficient S levels can’t meet crop needs. The good news: No such shortage applies to the many excellent S-containing fertilizer products that can address S deficiencies where they occur.

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.
