The source and the releasing processes of nonexchangeable K from the rhizosphere were evaluated by using a 0.01 M HCl sequential extraction that enables the detection of subtle depletion of nonexchangeable K in the rhizosphere. Rhizobox experiments were conducted in which maize (Zea mays L.) plants were grown on different K sources (non-allophanic Andosol, Fluvisol, biotite and orthoclase) for 17 days. Nonexchangeable K decreased significantly in the rhizosphere of Andosol, Fluvisol and biotite… CONTINUE READING
