Abstract
Surface soil samples from three chiefdoms were analyzed for soil health parameters such as pH, CEC (cmol kg-1), available N, P and K and exchangeable Ca and Mg. Soils are moderately to strongly alkaline, except for few samples in Barri and Kpaka chiefdoms which were strongly acidic demanding the use of lime in order to optimize the yield of crops besides fertilizer use. Organic carbon was low to medium in Gallines Peri and low to high in Barri and Kpaka chiefdoms. Available N was low to medium in Gallines Peri and Barri chiefdoms and low to high in Kpaka chiefdom. Available P was low to medium in soils of Gallines Peri and low to high in soils of Barri and Kpaka chiefdoms. On an average nearly 50% of soils in the study area showed P deficiency which demand proper application of P containing fertilizers to obtain optimum yield. Available K status was low to medium with higher K deficiency forBarri and Kpaka than Gallines Peri chiefdom which demands appropriate K application in order to achieve optimum yield. The exchangeable Ca and Mg status of soils was moderate which is adequate for most crops. Balanced fertilization is needed for sustained and enhanced productivity of crops in the district.
