Abstract: Totally 1820 geo-referenced surface soil samples covering 455 panchayat villages in 11 blocks of Ramanathapuram district were collected to assess the available sulphur and micro nutrient status in soils besides to create a data bank on soil fertility status including multi nutrient status. The study involved assessment and reassessment of multinutrient and single nutrient 1980-2000. From the present investigation, it is revealed that ZnCuB; FeZnCu and FeZnB was observed as three nutrient deficiencies in Ramanathapuram district with a mean of 17.9, 0.3 and 0.2 per cent respectively. Higher per cent of three nutrient deficiencies viz., ZnCuB was observed in Thiruvadanai block and lower per cent was observed in Nainarkovil. ZnCu registered the highest percentage of two nutrient deficiencies. Maximum individual deficiency of Zn, Cu and B nutrients observed as single nutrient deficiency with a mean of 26.4, 5.7 and 4.6 per cent respectively. The assessment revealed that percentage of deficient samples was 46.7, 4.1, 19.0 and 6.0 per cent was respectively for Zn, Cu, Fe and Mn.
