Item The Characteristics, Classification and Land Use Significance of Swell-Shrink Soils East of Lake Victoria, Kenya(Kenya Soil Survey, 1988) Gatahi, M.M.; Gachene, C.K.K.; Kenya Soil SurveyThe eastern gulf shores of Lake Victoria is an old lacustrine valley of Pleistocene period which has since been filled with alluvial and colluvial sediments derived from the surrounding volcanic hills and scaps to form a major plain. This plain slopes very gently into the lake. It is surrounded by Nandi Escarpment to the north Nyabando Escarpment to the south and volcanic hills to the east and North West.Item Occurrence, Utilization and Research Activities on Vertisols in Kenya(Kenya Soil Survey, 1982) Gatahi, M.M.; Kiome, R.L.; Kenya Soil SurveyVertisols and associated soils in Kenya occupy approximately 2.8 million hectares of land. This is equivalent to 4.9% of the total land area. Of this, 14% is found in relatively humid areas while 86% is in semi-arid to arid regions of the country. These soils are commonly referred to as "black cotton soils" or black cracking clay soils". They occur from the sea level to altitudes above 2,000 metres and are scattered all over the country as shown in Figure 1. Vertisols occur extensively in the Athi plains around Nairobi, Kano plains, Mwea Irrigation Schemes, Masai-Mara, Loita Plains and parts of North Eastern Kenya.
