Sulfur, like magnesium, has always been considered an essential element needed by the plant in fairly large amounts, but it is only in recent years that sulfur or its compounds have been used as fertilizer materials.
The sulfur needed by crop plants comes largely from the [SIZE=4]air, rainwater, and the decay of organic matter in the soil. Where fertilizer is used the sulfates present are important particularly in the low-analysis superphosphate that contains approximately 50 percent calcium sulfate.[/SIZE]
[SIZE=3]Sulfur deficiency may be expected, therefore, in areas distant from industrial centers, especially where there is not much decomposing organic matter and where fertilizers containing little sulfates are used.[/SIZE]
So now that the EPA is trying to stop factories from emitting Sulfur, farmers now need to add this element to their soil.
Every time government does one thing it usually affects another. :drink3:
