Published on July 22, 2013
Sulfur is often classified as a secondary plant essential element, mainly due to a smaller plant requirement, but also because it is less frequently applied as a fertilizer and applied in smaller amounts compared to other nutrients like nitrogen, phosphorus, and potassium macronutrients. However, if deficient, sulfur can have a dramatic effect on plant growth and crop productivity. This module will cover important concepts of sulfur management in agricultural systems for profitable crop production.
