Not some dude you know by that name but the element Molybdenum (Mo). Of the minor trace elements required by plants, Molybdenum (Mo) and Nickel (Ni) are those needed in the least quantity and were not even recognized as required trace elements until the mid (for Mo) to late (for Ni) 20th century. There is still even some question about whether Ni is needed by all plants. In my gardening I have generally operated on the faith based assumption that since I maintain soil pH in the appropriate range and use wood ash as a soil supplement (good source of trace elements) when available subject to the limitation of not pushing pH too high, trace element deficiencies were unlikely. By nature I am leery of faith based assumptions so recently when the State Ag lab lowered their prices I did a higher level soil test which includes some of the trace elements. Reviewing the results, the values for Mo and Ni were notable. Mo was below the lower limit of detection of 0.04 ppm and Ni was shown as 0.4 ppm. Something is fishy here as elsewhere I have seen typical soil concentrations of 0.5-40 ppm given for Mo and 5-500 ppm for Ni. While the desirable level for Ni is murky, I have seen 1-2 ppm given as optimum for Mo for most crops. I am suspecting there may be an error or deficiency in the lab protocol for these two elements. I am not inclined to attempt any corrective measures without more info. I called the county extension agent to discuss the test results but he was out of his element, so to speak, on my particular questions. He did commit to forward my questions to the soil scientists at the Ag school. I suspect that it will be a few weeks before I hear back. If the test results are legitimate it shouldn't be hard to supplement the soil up to desired levels since 1 ppm is likely all that is needed.
