Abstract
The status of root nodulation of Acacia auriculiformis, raised as plantations in Kerala was assessed by collecting soil samples from 26 plantations using soil core sampler. The study indicated that the average number of nodules varied depending upon the physical and chemical properties of the soil. A significant negative correlation was observed between soil organic carbon and nodule number. Generally there was an inverse relationship between the number of root nodules and soil fertility attributes. The acidity of the soil did not affect the root nodulation potential significantly.
