Soil and Fertilizer Sulfur

R Mikkelsen and R Norton

A continual supply of sulfur (S) is essential for plant growth. Organic matter is the largest reservoir of S in soil, but it must be converted to soluble sulfate before plants can take it up. The major source of S fertilizer is obtained from scrubbing fossil fuels. There are many excellent soluble and slowly soluble sources of S fertilizer that can meet plant nutritional requirements when applied at the right rate, time and place.
