Soluble Cations Beneath a Feedlot and an Adjacent Cropped Field¹

ABSTRACT

Concentrations of Na, K, Ca, Mg, Zn, Cu, Fe, and Mn in the soil solution were measured beneath a feedlot and an adjacent cropped field for a 12-month period. Only Ca, Mg, and Mn were higher in the feedlot soil solution than in the cropped field at the lower depths tested. At the lower depths, Ca and Mg appeared to be two to four times higher in soil solution from the feedlot than from the cropped field. Manganese was consistently higher beneath the feedlot than the field; however, Mn levels were low, and, with the limited water movement through feedlot soil, it is unlikely feedlots contribute significant Mn to groundwater.
