Abstract

Physical and chemical properties of irrigated soils were evaluated using standard methods. Soil properties varied according to farm. Moisture levels were low (1.00 ± 0.00 - 2.15 ± 0.01%). pH varied from slightly acidic (6.33 ±0.08) to slightly alkaline (7.40 ± 0.06), and was within the range for optimum growth for plants.CEC ranged from 5.05 ± 1.00 to 17.73 ± 0.03 cmol/kg, and was within the range for most soils. OM contents (14.08 ± 0.10 -24.37±0.41%) were high in all the farms. Nitrogen (0.01 ± 0.00 - 0.09 ± 0.00 mg/kg) and phosphorus (0.09 ± 0.00 - 1.78 ± 0.01 mg/kg) contents were low and high respectively. Ca2+ concentration varied from 0.42 ± 0.05 to 5.64 ± 0.04 mg/kg. Mg2+ levels (1.81 ± 0.02 - 3.62 ± 0.01mg/kg) were below the optimum range for soils.Clay (8-24%) and sand (64-82%) contents were relatively high. Irrigated soils were classified as sandy loamy. Significant and positive correlations (p ≤ 0.05) occurred for pH, OM and CEC.
