Abstract
Abstract The molybdenum status of 6 uncultivated Connecticut soils was studied in the greenhouse using lettuce (Black Seeded Simpson) and subterranean clover as test crops. Treatment effects were evaluated by visual appearance of the plants and by determining dry weight and nitrate content of the tops. Lettuce responded markedly to molybdenum applications on 4 of the soils at light rates of lime. Lettuce on another soil responded to molybdenum in terms of greater growth and lowered nitrate content of the tissue but no foliar differences were observed. Growth of lettuce on the sixth soil was depressed by molybdenum applications in early stages and the concentration of nitrate in the tissue at harvest was not lowered. Lettuce did not respond to molybdenum at heavier rates of lime on the 3 soils for which this information was obtained. On all 3 of these soils, the effect of heavier lime alone was greater than that of molybdenum at the lower rate of lime. Subterranean clover did not respond to molybdenum at light rates of lime on any of the 4 soils on which this crop was grown. Analysis of the clover tops for molybdenum indicated that more than 80% came from sources other than the seed on control cultures.
