In soil, most of the zinc stays bound to the solid particles. When high levels of zinc are present in soils, such as at a hazardous waste site, the metal can seep into the groundwater. Industries also can release dust containing higher levels of zinc into the air we breathe.
Add sorghum to a large pot of water. Use one cup of whole grain sorghum to three cups of water. Bring to a boil, reduce to a simmer and let cook for approximately 40-55 minutes or until the sorghum is tender. Drain any remaining liquid and serve.
Grain sorghum is used primarily as a livestock feed. Planted area generally rangedbetween 15 and 20 million acres until the late 1980's, when acreage dropped to the 10 to 15 million range. Themajority of the sorghum acreage not harvested for grain, is harvested for silage.
