Soil fertility evaluation based on soil test is an inevitable pre-requisite for predicting fertilizer needs of
crops. Fertilizer recommendation based on crop requirement and soil nutrient availability is one of the
criteria to enhance nutrient use efficiency. In the present scenario of increasing fertilizer cost and over
concern on human health, there is an urgent call from all corners for the rationalization of the existing
package of practices (POP) recommendations for nutrient management based on innate soil fertility
and crop requirement. In this regard, Kerala State Planning Board in collaboration with the Department
of Agriculture, Government of Kerala, has initiated a project to develop soil based plant nutrient
management plan for Kerala. The Central Tuber Crops Research Institute under Indian Council of
Agricultural Research, one of the collaborators of this project, has evolved plant nutrient management
plan for Pathanamthitta district based on chemical analysis of 10348 soil samples collected from
various crops of the 51 panchayats of the district. As this district is one of the major tuber crops
growing zones of Kerala, and 36% of the soil samples received from the district pertained to tuber
crops viz., cassava, elephant foot yam, yams, taro and tannia, an effort was made to prepare a
nutrient management plan for these crops based on the soil test data generated. This paper deals
with the innate fertility status (major, secondary and micronutrients) of the tuber crops growing soils
as well as the nutrient management strategy developed for these crops based on soil test data. The
soil test data indicated that the soils were strongly acidic with high organic C, available P, exchangeable
K, Ca, Mg and S and sufficient in all micronutrients viz., Fe, Cu, Mn, Zn and B. As the overall soil
nutrient status of the district was found high, application of all the above nutrient containing fertilizers
can be restricted to location and crop specific depending upon soil status and crop needs. As tuber
crops form one of the major component crops of almost all predominant cropping systems of the
district, the soil test data indicated the need for refinement of the existing package of practices of
manures and fertilizers to maintain soil health and ensure higher income to farmers
