Item A Preliminary Investigation of the Soil Resources of Kiteta Location Machakos District, 1978(Ministry of Agriculture, 1978) Muchena, F.N.; Njoroge, C.R.K.; Ministry of AgricultureThis report deals with a site evaluation of Kiteta Location, Maohakos District which was carried out during the second half of August 1977. The surveyed area comprises about 8,285 hectares. The various landforms and associated soils are indicated on the accompanying Boil map at scale 1:50,000. In chapter 3 the various mapping units are described. Then in chapter 4 the land is evaluated for irrigated agriculture surface irriga- tion and overhead irrigation. The evaluation is based on the assumption that good-quality irrigation water is available. The suitability classes of the various mapping units are indicated in Table 3. Some conclusions and findings of the site evaluation are outlined in chapter 5.Item The Soils of a Part of the Bottomlands of Ngoru Estate (Kiambu District) 1981(Kenya Soil Survey, 1982) Njoroge, C.R.K.; Thiang'au, P.K.; Ministry of Agriculture; Ministry of AgricultureFollowing a request through the Scientific Research Division of the Ministry of Agriculture, an investigation of the soil conditions of a part of Ngoru Estate (Kiambu District) was carried out in March, 1981. The main objective of the request was to assess the irrigation suitability of the soils of Ngoru Estate bottomlands for cultivated pasture, horticultural and fodder crops. The Ngoru Estate is situated about 14 km east of Kiambu town and about 1 km off the Kiambu Nairobi road. To the west and to the south the estate is bounded by the new Kiambu Municipality boundary and Riara river respec- tively. Generally, the survey area is easily accessible and well served with motorable farm roads. During fieldwork, the only available farm map of average scale 1:7,200 approx. was used. After the aerial photograph scale 1:12,000 approx. was obtained and enlarged to scale 1:3,000, all soil boundaries and observations were transferred to the enlarged photograph from which a base map was compiled.Item The soils of Eldoret International airport farm and their suitability for arable crops: Uasin Gishu District. Kenya Soil Surveys No S31 2002(Kenya Agriculture Research Institute, 2002) Njoroge, C.R.K.; Owenga, P.O.; Kimotho, P.W.; Gicheru, P.T.; Kenya Agricultural Research Institute; Kenya Soil SurveyThe request to carry out a soil survey of Eldoret International Airport Farm was made by the General Manager of Kenya Airports Authority, Nairobi. The objective of the survey was to carry out soil investigations on approximately 327 hectares of land and to assess the soils suitability for rain fed arable crops (e.g. maize, wheat and beans) growing.
