Sulfur Response Based on Crop, Source, and Landscape Position

Sulfur responses can be seen in almost any crop in the northern Plains of North America if soil sulfur availability is low. Canola (Brassica napus L.) is a crop grown in this region with special requirements for sulfur. Crops growing on soils with low organic matter that are coarse-textured are more susceptible to sulfur deficiency. Within fields, eroded hilltops and slopes, especially when consisting of coarse-textures, respond more to sulfur application than higher organic matter soils in depressional areas. In this region, sulfur source is important. Elemental sulfur, even if formulated with bentonite, does not alleviate sulfur deficiency as well as sulfate-containing amendments.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
