The potassium content of little bluestem (Schizachrium scoparium (Michx.) Nash), kleingrass (Panicum coloratum L.), and brownseed paspalum (Paspalum plicatulum Michx.) declined following plant senescence and frost. The potassium content of herbage of little bluestem and brownseed paspalum reached levels below the requirements of cattle by February during two winters. Kleingrass leaves retained green tissue the first winter yielding higher potassium levels. Little bluestem had reached senescence and had low levels of potassium by November. Herbage of the three species was also subjected to soaking treatments to simulate frost damage and quantify losses due to leaching. Potassium levels declined with soaking in freeze damaged herbage as time of exposure increased. Soaking treatments did not significantly affect the potassium content of fresh live herbage.
