Assessment of Physical Suitability of Soils for Vegetable Production in the Libga Irrigation Scheme, Northern Region, Ghana Using the Analytic Hierarchy Process and Weighted Overlay Analysis

Assessing the suitability of soils for agricultural production is critical in promoting sustainable agriculture. Knowledge gained from soil analysis provides sound basis making informed decisions about management and crop selection a given area. In view this, this study was carried out to assess physical Libga Irrigation Scheme cultivation jute mallow (Corchorus olitorius), tomato (Solanum lycoperscum L.) cabbage (Brassica oleracea var capitata). Soil samples were collected at 0–30 cm 30–60 depths 50 geo-referenced points located nodes 100 m × regular grid. Particle size distribution, bulk density, total porosity, field capacity, permanent wilting point, available water saturated hydraulic conductivity, electrical conductivity pH determined following standard laboratory protocols AGSSIP Laboratory University Development Studies, Nyankpala campus, Ghana. Weighting properties achieved through analytic hierarchy process (AHP). maps selected crops produced using weighted overlay ArcGIS (10.5). The results showed that generally 44.3 ha (76.4 %), 44.7 (82.2 %) 55.7 (96.0 irrigation are moderately suitable mallow, respectively. major limiting factors high BD acidity levels. AHP proved be very useful tool incorporation farmers’ views into decision production.
