ABSTRACT
The study assessed and analyzed the soils of Abdullahi Fodiyo University of Science and Technology Teaching and Research Farm, Aliero, Kebbi State, Nigeria. The study considered; soil chemical properties, map and analyze the soils of the Study Area. A preliminary survey was initiated to familiarize and select sampling locations, followed by grid survey on 50ha land at a scale of 1:25,000. Land gridding at 100m x 100m intervals apart was undertaken. Baseline was established, followed by augering along intersects for surface sampling of soils to determine boundaries based on differences in soil properties. In each soil mapping unit identified, soil profile pit was dug, described, soil sample collected and labeled from genetic horizon, from bottom up to minimize falling debris contaminants, for laboratory analysis. Each profile pit was dug to standard size; 150cm length, 100cm width and 200cm depth. The description was in accordance with international guidelines. Data set of measured parameters were subjected to descriptive statistics using mean, range and percentages. Three mapping units were identified and labeled ARF1, ARF2 and ARF3. Result from laboratory analysis revealed that soils fertility was low as indicated by low values of 0.09gkg-1, 1.26%, 0.73% 6.70mgkg-1 and 1.46cmolkg-1 representing TN, OM, OC, AP, and CEC respectively. The soils were slightly sodic and non-saline based on ESP and EC ratings. Data on soil chemical properties, would enable understanding, fertility and potential uses of soil, while assisting stakeholders, researchers, farmer and extension agents to properly manage soils of the study area.
