| Abstract: | Soil Mo contents in soils of China ranges from 0.1 to 6 mg/kg and the variation is primarily due to soil type and secondly, parent material. Soil Mo deficiency was observed in many soils mainly in two regions. Both total and available (oxalic acid and ammonium oxalate extractable) Mo contents are low in loessial soils and alluvial soils along the Yellow River, whereas only available Mo is low in acidic soils in the south of China. Soil available Mo contents was mapped into 5 grades on a scale of 1: 10,000,000. A map of delineation of Mo deficient soils was compiled as well. |
