Fertility status and management of USSE OFFOT inland valley soils for increased cassava yields Inakwa-Ibom State, Nigeria
Abstract
Inland valley soils of USSE OFFOTin Akwa Ibom State, Nigeria grown to cassava were characterized with the aim of knowing their fertility indices. Soil samples were made representing the top (0-15cm) and sub soils (15-30cm) and were analyzed. The soils were characterized by strongly to moderately soil reaction (pH 4.26 5.12), low organic C (0.72 1.88%), low total N (0.13 0.19%), high available Bray -1P (73.33 93.32 mgkg ), low exchangeable Na (0.02 0.05 cmol(+) kg and Effective Cation Exchange Capacity (ECEC). Management measures to be adopted by the farmers to raise the fertility status of the soils were suggested for increased cassava yields.
