Geospatial Mapping and Classification of Soil Fertility Status of Chochi Irrigation Farmlands for Effective Crop Production in Yola South LGA, Adamawa State

Abstract

This research work saddled to study the geospatial mapping and classification of soil fertility statuses of Chochi irrigation farmlands for effective crop production in Yola South LGA, Adamawa state. Forty (40) samples were collected in the area at the depth of 0-20 cm and 20-40 cm making 80 soil samples respectively. Three standard (3) profile pits were dug where soil samples were collected from the identified horizons of each pit. The collected soil samples were analyzed in the laboratory and used I for mapping and classification of the soil and its fertility statuses using Fertility Capability Classification (FCC) System. The spatial mapping results shows that the southern part of the study area has dominated with slightly acidic moderate to high OM, TN, Av- P and K content while the northern part was neutral with low to moderate values respectively. The FCCC classified the soil with the following symbols; LCds-n-km at pit 1, SCds-n-km at pit 2 and pit 3 classified as SLds-n-km. it is therefore recommended that to realize effective irrigation practices integrated nutrient management should be adopted.
