Item Coffee Research Foundation Kenya Annual Report 1988/89(Coffee Research Foundation Kenya, 1988/89) Coffee Research Foundation KenyaThe coffee research services in Kenya commenced with the appointment of the first Government Entomologist in 1908. A few coffee experiments were established at Kabete and Kibos Experimental Farms in 1910-12. The coffee research team gradually increased with the appointment of a Mycologist in 1913 and a Coffee Plant Inspector from Jamaica in 1914.Item The Distribution, Characteristics and Some Management Aspects of Acid Soils in Kenya(Kenya Soil Survey, 1980) Kenya Soil Survey; Kenya Soil SurveyAcid soils cover an important part of Kenya's land surface.They are concentrated in four main areas namely: Western, Central, Eastern Kenya and Coastal belt. For the purpose of this paper, it is necessary to define what is meant by "acid soil". Hereafter, an acid soil is considered as a soil whose pH ;(water 1:1 v/v) is lower than 5.5 in the B-horizon. This definition is in conformity with acidity classification followed by the staff of Soil Chemistry Section at National Agricultural Laboratories in Nairobi. The major soil groups in Kenya that fall in this category of acid soils according to Kenya Concept (Siderius and van der Pouw, 1980) and the FAO (1974), terminology are Andosols (humic and mollic), Ferralsols (rhodic and orthic) Nitosols (mollic, humic and dystric), Acrisols (humic and chromic) and Cambisols (humic and eutric) •Item The Distribution, Characteristics And Some Management Aspects Of Acid Soils In Kenya(Ministry Of Agriculture, 1974) Wokabi, S. M.Acid soils cover an important part of Kenya's land surface. They are concentrated in four main areas namely: Western, Central, Eastern Kenya and Coastal belt.

This can be achieved through increased and sustainable agricultural production, particularly in developing countries where >60% of the population's livelihood depend on agriculture (Paarlberg, 2002). Halving hunger by 2015 will be achieved through intensification of crop production (Millennium Taskforce on Hunger, 2004). In many acidic soils in developing countries, P deficiency exacerbated by the high P fixing capacities are the main limiting factors for crop production and therefore, P remains, one of the main keys for agricultural sustainability (Chien and Menon, 1993). Therefore, P replenishment is indisputable and requires application of external P sources (Mokwunye and Bationo, 2002) for improvement and sustainability of agricultural production.Item Ministry of Agriculture - National Breeding Station Annual Report 1983(Ministry of Agriculture, 1983) Ministry of AgricultureThe copper trials on rapeseed showed significant difference bet1."Jeon wheat and rapeseed in their phosphorous copper nutrition. It was determined that in conjunction with small research trials by NPBS, larger scale trials over u wide area 'Would be necessary to determine whether there are even small responses to copper application on rapeseed East African Industries wish to cooperate -in this research
