In a recent blog post, Dr. Murdock talked about temporary sulfur deficiency in corn. Below are some images of what we believe to be sulfur deficiency and a couple images of zinc deficiency for comparison. The two can be a bit confusing in some instances.We do not expect the sulfur deficiency symptoms in these images to lead to yield losses. Once we get rain, the symptoms should dissappear.
|Suspected S Deficiency. The symptoms are similar to minor dificiencies in Zn or even N. Field history and climate conditions suggest S as the most likely culprit. We would not expect a yield loss from this.|
|Zn Deficiency. This is a more severe deficiency where the nodes appear "stacked" on top of each other.|
