“…Partridge pea does furnish cover to areas which otherwise might be bare or weed infested (Young 1952, Haugen andFitch 1955). Colom and McCalla ( 1952) found that the nitrate content of field plots previously grown to partridge pea (plant parts removed) was higher than that of plots without a legume but not as high as if sweetclover ( M elilotus alba) was used. In time, through nitrogen fixation and soil stabilization, partridge pea may improve a non-stable site or eroding area sufficiently to allow succession to proceed (Goodding, Duley, and Russel 1949).…”

Partridge pea frequently occurs on non-stable sites and in Illinois occurs most often on silty clay loam soils. There· was no tendency to occur on· sandy sites as has been previously reported. Partridge pea occurs on soils with a wide range of pH values and on sites with both low and high phosphorus values. Low phosphorus values predominate in both the slowly and readily available forms. Partridge pea stands generally occur on soils with very high levels of available potassium but also occur on sites quite deficient in potassium. Total, mineral, and extractable calcium (measured as CaO) were pre·sent in partridge pea site soils in amounts ranging from .40 to 2.55%, .22 to 1.31 o/o, and .03 to 1.27%, respectively. Soils with partridge peas growing on them have a wide range in total nitrogen content but low values less than .181% predominate. These soils also generally have a low rate of nitrate production. Low nitrate production and/or low levels of available phosphorus may restrict the growth of other species on sites where C. fasciculata occurs. Total nitrogen and nitrate production, however, were not related to the amount of phosphorus. Subsoil clay content did not seem to be a factor in partridge pea stand occurrence. The species' ability to grow under some adverse conditions and on non-stable sites, including eroding areas, indicates that it is a species which might have a use similar to Korean lespedeza (Lespedeza stipulacea L.).
