All the magnesium applied to the soils is not utilized and part of it is fixed depending upon the quantity of magnesium applied and the type of soil. Prince et al. (1947) observed that degree of fixation of magnesium in-creased by application of magnesium. Fixation of applied magnesium was also reported by McLean and Carbonele (1972). Prince (1951) observed that more than half of the applied Mg could not he accounted for in the harvested crops or in the exchange complex of the soils. Presumably the unaccounted portions were either fixed in the non-exchangeable form or lost in the drainage water.
