e0“Experiments were conducted on a peat soil in the greenhouse to determine the effects of Mo and lime on the leaf tissue Mo concentration and yield of red clover (Trifolium pratense L.), onions (Allium cepa L.), cauliflower (Brassica oleracea var. botrytis L.), lettuce (Lactuca sativa var. capitata L.), and carrots (Daucus carota L.)”
e1“Increases in soil pH from 4.3 up to 6.9 resulted in yield increases of all crops except lettuce”

- Intervention effect Increasing soil pH from 4.3 to 6.9 increased red clover yield.
- Intervention effect Increasing soil pH from 4.3 to 6.9 increased onion yield.
- Intervention effect Increasing soil pH from 4.3 to 6.9 increased cauliflower yield.
- Intervention effect For onions, the Mo seed treatment alone was sufficient for optimum yield.
- Intervention effect For cauliflower, the Mo seed treatment alone was sufficient for optimum yield.
- Intervention effect For lettuce, the Mo seed treatment alone was sufficient for optimum yield.
- Observation No visual abnormal leaf symptoms occurred in red clover at leaf tissue Mo of 192.
- Observation No visual abnormal leaf symptoms occurred in cauliflower at leaf tissue Mo of 640.
- Observation No visual abnormal leaf symptoms occurred in onions at leaf tissue Mo of 1,018.
- Association Mo and lime showed synergism in tissue Mo concentration of onions.
- Association Mo and lime showed synergism in tissue Mo concentration of cauliflower.
- Association Mo and lime at high levels showed antagonism in yield of cauliflower.
- Association Mo and lime at high levels showed antagonism in yield of carrots.
- Intervention effect Molybdenum applications of 4.5 ppm or higher gave red clover tissue with Mo greater than 10 ppm, which could be toxic to cattle.
- Intervention effect Liming generally increased the molybdenum concentration of the crops.
