Why do plants need SULFUR??

Jan 28, 2009Some soil sulfur occurs naturally from the weathering process of minerals. In some circumstances like sandy soils, the sulfur in soil solution can leach into our water systems. In water-logged soils, sulfur can be converted by microbial activity into a gas, and escape into the atmosphere. Soil sulfur can also react/bond with iron and become insoluble.

Sulfur: Mineral, Native Element, Nutrient. Its uses and

Sulfur reacts and forms compounds with all elements except gold, iodine, iridium, nitrogen, platinum, tellurium, and the inert gases. Sulfur is abundant and occurs throughout the Universe, but it is rarely found in a pure, uncombined form at Earth's surface. As an element, sulfur is an important constituent of sulfate and sulfide minerals. It occurs in the dissolved ions of many waters.
