Abstract
IN the course of work on the minor element constituents of Chilean nitrate, the value of molybdenum in improving the growth and health of lettuces has been apparent. With one part of molybdenum (as sodium molybdate) in ten million parts of nutrient solution the plants are larger, deeper green and appear to be much more resistant to disease. This improvement occurs whether the molybdenum is used alone or in conjunction with one or more other minor elements as strontium, titanium, vanadium, chromium and zinc. Preliminary experiments even suggest that molybdenum can fend off symptoms of boron deficiency for some time in the early stages of growth, but this point needs confirmation.
