Abstrakt: Molybdenum toxicity in ruminant animals is a soil‐related nutritional problem on wet floodplains of some small streams in Oregon. The soils of these floodplains have large amounts of Mo (2 to 6 ppm) inherited from their parent materials. The Mo content of legumes increased with increases in the Mo content of calcareous soils formed in granitic alluvium. In highly‐leached acid soils from shales, the plant content did not increase consistently, but the amounts in the plant were still within the toxic range (10 to 20 ppm) for grazing animals.
