Abstract The physical and chemical characterisation of Anambra State College of Agriculture at Mgbakwu, Awka North Local Government Area was conducted using composite samples from two representative profile pits. Six soil samples were collected from various depths, dried, sieved with 2 mm sieve and subjected to a routine soil analysis and the characteristics of the soils described. The findings from the study shows that the texture of the soils varied from loamy sand to sand clay loam, with the total sand ranging from 640 – 840 gkg-1, clay from 70 to 290 gkg-1 and silt 50 – 90 gkg-1. The soils reaction (pH) is extremely acidic to moderate, ranging from 4.1 to 5.8. The available phosphorous of the soils is very low, 1.87 to 3.73 mgkg-1. The exchangeable bases, organic matter, carbon, cation exchangeable capacity (CEC) and percentage nitrogen of the soils were observed to be low. Generally, the result of the study revealed that the nutrient elements tested were below their critical level and therefore need to be upgraded in soil nutrients through soil amendment to produce maximally.
