SuleimanA. 4200884This study was conducted to assess the soil fertility status and the extent of soil sodicity and salinity in the Kano River Irrigation Project (KRIP), located between latitudes 11°32N to 11°51N and longitudes 8°20E to 8°40E in the Sudan Savanna of Nigeria. Soil samples were collected from the entire project area using stratified random sampling technique. Questionnaires were used to obtain information on farmers soil and water management practices. Soil sodicity was the most serious problem in the area. The exchangeable sodium percentage in the top soil ranged from 3.1 to 34.4 with an average of 14.8, while in the subsoil the range was from 3.1 to 40.6 with an average of 17.5. Soil pH values ranged from 5.6 to 9.5 and 4.8 to 9.6 in the top and subsoil, respectively. About 53% of the farmers interviewed cultivated on their field drains, a practice that has led to the blockage of most of the field drains in KRIP and resulted in waterlogging.]]>Abubakar, S.Z., J.M.
