    (taylor & Francis, 2024-07-31) Nungulaa, Emmanuely Z.; Massaweb, Boniface J.; Chappac, Luciana R.; Nhundab, Daniel M.; Seleimand, Mahmoud F.; Alie , Nawab; Gitari, Harun I.
    this study aimed to use a GiS-based approach in producing soil fertility maps and utilize the spatial data on achieving site-specific management of major nutrients in Morogoro, Tanzania. Soil samples were collected in six mapping units and analyzed for chemical properties such as ph, cation exchange capacity and electrical conductivity. arcGiS 10.8 was used to produce nutrient variability maps of organic carbon, available p, total nitrogen and exchangeable K, ......
