Severe foliage chlorosis has been observed for oats (Avena sativa L.), grown in rotation with tomatoes (Lycoperiscon esculentum Mill.) sprayed with copper hydroxide [Cu (OH2)] to control bacterial diseases where soil Cu level was near 100 mg/kg. This research was conducted to determine P concentration of oat plants as a function of soil-Cu at three lime rates. Oat plants were grown 7 wk in pots containing 2 kg of soil each from the A horizon of Orangeburg loamy fine sand (fine-loamy, siliceous thermic Typic Kandiudult).Copper rates of 0, 100, 200, and 400 mg/kg of time to give a factorial arrangement of 12 treatments, with all treatments receiving 100 mg/kg P. A treatment containing 200 mg7kg P, 400 mg/kg Cu and 6 g/kg lime was also included. Dry-matter yield of oat shoots and roots; tissue content of Cu, P, and Ca; soil-test Cu, P and Ca; and soil pH were determined. Copper concentration in oat plants was positively correlated (P<0.001) with applied Cu, while P concentration, P uptake, and plant dry weight were negatively correlated (P< 0.001) with applied Cu. Yield of oat plants was almost doubled by increasing P from 100 to 200 mg/kg with 400 mg/kg Cu and 6 g/kg lime. The data suggest that Cu toxicity of oats is due to Cu-induced P deficiency.
