| Abstract | The objective of this study is to assess the acidity and salinity of irrigation water and soils in the northern Niayes zone. Seven soil profiles were described and their texture measured. Soils were sampled from the 0 - 20 and 20 40 cm horizons and water was taken from horitcultural watering wells. Our results show that most of the seven profiles are represented by strongly sandy soils. Soil pH varies among sites but there was no significant difference between shallow (0-20) and deeper (20 - 40) fractions. Soil salinity, however, does vary according do both site and sampling depth, with more saline soils at the surface. Factorial correspondence analysis results show a gradient of both acidity and salinity and discriminate two main groups of soil and water. The first group is constituted by alkaline and saline soils and water. The second group is composed of acidic and non-saline soils and water. This study facilitated the identification of two key zones : an inland area subject to high acidity and a littoral area subject to high salinity. These two factors considerably limit agricultural production. |
