| 1 | Digital mapping of cultivated land in two Peri-urban areas of Ibadan, Nigeria. |
The need to save time, money and enhance quality as well as precise soil survey information through improved methodologies calls for digital soil mapping: hence, this study was conducted to map the peri-urban soils of Ajibode and Lade in Ibadan metropolis with digital method. Detailed soil survey using grid method was employed to cover the entire representative area for the study. Observation points were taken at a 100-meter interval. Six profile pits were dug, each at the three predominant land types viz: upper, middle and valley bottom in both loca-tions. Profile pits were described and sampled for physical and chemical analyses following standard methods. Soil samples were collected at 0 -15cm and 15 -30cm and further subjected to geospatial techniques for maize and cassava soil suitability production. Soils in Ajibode were classified as Iwaji Balogun and Oba series and fitted into Quartz-udic psamment according to USDA (2010) soil tax-onomy system but correlated as Fluvisols following (FAO/UNESCO 2006). At Lade, soils were classified as Iwo, Balogun and Matako series. Iwo and Balogun series fitted into Rhodic-ustalf according to USDA (2010) and fitted as Lixisol in FAO/UNESCO (2006), while Matako series fitted into Dystric-fluvaquent (USDA, 2010) but qualified as Fluvisol FAO/UNESCO, (2006). Soils in Ajibode varied between moderately to marginally suitable for maize and cassava. In con-trast, at Lade, it varied between moderately to marginally suitable for cassava and non-suitable for maize production. Mapping of soil using geospatial method helps to increase the efficiency of soil mapping, and thus recommended for preci-sion and sustainable agriculture. | 6. Tobore, A. O., Alabi, K.
