The present study aims to analyse the interrelationships among the thirteen soil fertility parameters based on 678 samples from Ernakulam and 788 samples from Kottayam district. The Pearson’s correlation coefficient was estimated and tested its significance. The results of the analysis indicated positive significant correlation between electrical conductivity (EC) and available phosphorus in Ernakulam (r = 0.620) and Kottayam (r = 0.530) districts. EC was also positively correlated with Ca (0.406) and Fe (0.432). There was positive correlation between pH and K, EC and S, organic carbon and Fe and K and Ca in Ernakulam district while B showed a negative correlation with pH and Ca. Boron was negatively correlated with K, Mg and Mn while a positive correlation was observed between B and Zn (0.573) as well as Cu (0.417). Fe and Mn were negatively correlated (-0.467) while Zn and Cu showed a positive correlation (0.596)
