Climate, Soil and Topography
With exception of very few slopes, the district is relatively homogeneous with gently undulating plains intersected by seasonally flooded valley bottom soil.
In the extreme north east this pattern gives way to open flat land suitable for cultivation and covered by well or moderately drained soils with textures of sandy loams.
The soils vary between red lateritic earth grey sand to silt hardpan and iron crust “mbuga”.
Moreover, there are sandy clay loams and reddish coloured soils on inter flute slopes that are saturated with water within 100cms of the surface during the growing season.
The majority of these soils have high nutrient contents and are considered suitable for a wide range of food and cash crops and therefore have the potential for profitable cultivation.
Uyui district soils can best be described at best as moderately fertile.
The district receives rainfall of between 750mm and 950mm annually, falling between the months of October or November and December and a dry season from January to February or March and a second lower peak occurs in February or March and the rains then tail off in April or sometimes May.
Drainage System
Uyui district forms part of the vast central plateau of Tabora region, an area of flat and gently undulating plains broken in places by prominent hills.
Most parts of the district lie between 1,100 meters and 1,200 meters above sea level and form the main watershed separating rivers flowing north eastward into the Manonga River and the Wembere Swamps.
The district harbours the second largest basin in the region, that of the Manonga river and Wembere Swamp, draining ultimately into Lake Eyasi.
