Abstract
The study was conducted in irrigated vegetable farms around Lake-Alau Dam of Maiduguri, Borno State, to assess the current salinity/sodicity level in both soil and water samples. Six surface (0-15cm) and six sub-surface (15 - 30cm) soil samples were obtained each from two wings (South and North) at the site. Three water samples were also obtained from the site (intake, in-field and field drain). Laboratory analyses were conducted to determine different physico-chemical properties of the soils and water samples. Results of the soil analyses showed that, the soils were slightly acidic to neutral (6.72-7.08) in reaction, low in organic carbon (2.82-3.00gkg-1), ECEC (3.45-5.20 cmol (+) kg-1), EC (0.36-0.52 dsm-1) and SAR (0.11-0.15). These revealed that, there was no salinity problem in the soil at the time of the research in the area. Water samples analyzed from the In-take, In-field and Field-drains showed increased pH (7.42-7.91), SAR (0.66 - 1.44) and EC (0.71 - 0.78 dS/m) as water move from the In-takes to Field-drains. These also showed that, in the mean time crop production would be faced with minimal problems in the area. Organic and inorganic materials need to be in-cooperated in the soil so as to raise the fertility status of the soils.
