I have seen several sweet corn fields lately that have sulfur deficiencies (fig 1). One of the possible reasons we are seeing more S deficiency is because less sulfur is being deposited into the soil from the atmosphere due to reductions in acid rain. In 1986 about 24 lbs/a of sulfate were deposited in Maryland soils per year, however in 2011 it was closer to just 8 lbs/a each year. Organic matter supplies most of the sulfur to the crop, but sulfur must be mineralized to sulfate-S to be taken up by crop plants.

Over the years I have seen dark spots on the foliage of strawberry plants like the ones in figs. 1 and 2. These spots can look pretty bad at times and are thought to possibly be the start of some disease such as angular leaf spot or anthracnose.
