The objective of this work is to assess the variation of macro nutrients (N, P, K, Mg, Ca), OM, and soil pH along the slope gradient to improve crop production and to make a fertilizer recommendation of Irish potato crop in Nyabihu hilly land. Soil samples were collected in 0-30 cm soil depth after one year of radical terraces establishment and one season of Irish potatoes cropping. 9 soil sub-samples to form 3 composites samples were collected systematically (horizontally method). After soil laboratory analysis of pH water, pH KCL, available phosphorus, organic matter, organic carbon, total n...
