Iron interference in Mo determination in Mehlich-1 and Mehlich-3 soil extracts
, 2009 Among the essential plant nutrients, molybdenum (Mo) has the lowest concentration in soils. A routine method for the determination of soil Mo availability is not yet established. Soil analysis methods have been tested but not one has been set to be used in a routine basis in Brazilian laboratories.
