Abstract
Abstract Because previous liming experiments in northern Alabama showed that critical soil pH for soybean [ Glycine max (L.) Merr.] varied widely among sites, an on‐farm research program was initiated to delineate the separate effects of likely acid‐soil infertility factors in the area. Factorial treatments at 15 test sites included lime and Mo at rates of 0 and 4500 kg ha −1 and 0 and 100 g ha −1 , respectively. Thirteen experiments showed yield increases from liming, 12 of which also showed yield increases to Mo. Yield responses due to correction of only Mo deficiency occurred in five experiments while liming appeared to alleviate Al toxicity, as well as Mo deficiency, in six. Increased Mo availability was accompanied by increases in soybean leaf‐N and by increased seed weights. The soil parameter that correlated best with Mo deficiency was the Fe/Mo ratio from an acid ammonium oxalate extract. The critical ratio was about 1540. Molybdenum deficiency in soybean was found to be widespread.
