dc.description.abstract | The red soils occupy some parts of Mwea Irrigation
Scheme. In particular, the Tebere Section of the Scheme
has these. soils occurring at higher elevations than the
black cotton soils which occur in the depressions. The
black soils are irrigated under rice cultivation. The red
soils in Tebere are irrigated to a limited extent. The
irrigated plots are grown with vegetable and fruit trees.
The red soils (kaolinitic clay loams) have extremely
high infiltration rates. The result of their irrigation is
that water percolates into deeper layers, consequently
finding its way by seepage to lower lying black soils.
The main canals which supply irrigation water to
Tebere Section also run over the red soils. For all their
lengths the canals (left and right branches) are not lined
and therefore water losses from them is a possible source
on the drainage problems , However, the total surface area
of the canal is far less than that of the basin and furrow irrigated
plot on which water use efficiency has been studied.
Although the present study reveals that canal losses
and deep percolation losses contribute substantially to the
poor drainage of the black soils, rainfall has also been
identified as an important component. | en |
