Abstract
A chlorosis of Ladino clover, which was attributed to a shortage of molybdenum on St. Onesime stony loam, did not appear unless sufficient superphosphate was applied. An excessive amount of superphosphate has rendered the chlorosis more acute. The situation could be corrected by applying to the soil either 1 pound of sodium molybdate or 100 pounds of ammonium nitrate or 2 tons of limestone. This tends to prove that the trouble was one of nitrogen deficiency induced by the lack of molybdenum. Greater yield increases could be obtained, however, with additions of nitrogen or limestone than of molybdenum. Therefore, the latter could not take the place of the former, at least not completely but, under the conditions of the experiment, the reverse seemed possible. Tissue content of molybdenum, nitrogen and phosphorus correlated with growth data.
