Official State Soil: Port
February 28th

Port soils are very fertile, thanks in part to the prairie grasses they support. Over hundreds of years, the grasses' deep, fibrous roots added organic matter to the soils, producing a thick, fertile surface layer. Today, most Port soils grow alfalfa, wheat, and cotton. Some Port soils are pasture for horses or rangeland for cattle.
