Abstract

An assessment of variation in physico-chemical parameters, concentration of macronutrients, and trace
elements was undertaken during the two major seasons of Kanyakumari district to determine the fertility
status of the soil. The available macronutrients such as N, P, and K were analyzed by quantitative analysis,
colorimetric analysis, and flame photometer, respectively. The available trace elements concentration was
determined using atomic absorption spectrophotometer. The analyzed results indicated that both in the wet
and dry season, macronutrient, potassium, and trace elements such as Zn, Fe, and Mn were insufficient range
other than available nitrogen and available copper. Among the five sampling locations, sampling location S 5
showed stronger acidic nature and had a higher content of organic carbon, available P, Fe, and Mn during
both the seasons.
