Spatial and seasonal variations in surface water quality of the Mkondoa River, Tanzania

Surface water quality was examined to determine spatial and seasonal variations in the Mkondoa River, in an agricultural area at Kilosa, Tanzania. Five sampling stations were chosen spatially along the river continuum to reflect a consideration of all possible activities that are capable of affecting the quality of the river water. Triplicate samples of physical water parameters were collected on a monthly basis at each...

Soil fertility assessment and determination of potential ameliorants for an Alfisol under long-term continuous cultivation in southwestern Nigeria

Soil fertility declines following continuous cultivation along with the use of fertilizers causing concern for sustainable food productivity. This study assessed chemical properties of degraded Alfisol, and also evaluated potential of organic residues and fertilizers in improving them. Soil samples (0 to 30 cm) of degraded and fallow fields were collected and analyzed. One kilogram each of soil from degraded field was...
