Item Characterization of AOP Project sites for Gums and Resins production: Integrating Socio-Economic issues with biophysical information for the rehabilitation of the degraded arid and semi-Arid lands in Kenya. KARI-NARL-KSS M 90 2006(Kenya Agricultural Research Institute, 2006) Muga, M.O.; Esilaba, A.O.; Keya, G.; Wanjogu, C.R.K.; Maingi, P.M.; Kenya Agricultural Research Institute; Muya, E.M.; Lelon, J.K.Kenya is an agricultural country, depending almost entirely on land productivity for subsistence and socio-economic development. However, about two-thirds of the country is semi-arid to arid. Rainfed agriculture is confined to the remaining one-third of the country. The pressure is exerted on the fragile ecosystems that characterize these lands by the rapidly increasing population, thereby increasing land degradation. Since the main objective of Acacia Operation Project is to rehabilitate the degraded land and enhance its productivity for gums and resins, baseline information on the current state of land degradation is required against which the impacts of the proposed intervention and relative degree of desertification in future can be assessed. This has been done by evaluating the interactions between climate, relief, soils, vegetation and land cover, and their influence on biological functions, at both national, regional and site levels. Also, the indicators of land degradation have been reviewed. At the micro-catchment level the physical, hydrological and biological properties of soil have been evaluated as the basis of comparing the impacts of Delifino and Treno ploughs in rehabilitating the degraded land.Item Dryland Beans: Plant KALRO Dry Land Beans to Reduce Poverty and Raise Incomes in Arid and Semi-Arid Lands(Kenya Agricultural & Livestock Research Organization, 2017) Kathuli, P.; Golicha, D.; Kimotho, L.M.; Ngutu, M.N.; Maingi, P.M.; Adongo, A.; Kenya Agricultural and Livestock Research OrganizationBeans are the most widely used pulses in the dry lands. They are grown in low, dry and warmer areas and are a major source of proteins in cereal-based diets. Large amounts of beansare sold locally in urban centres and are alsoexported in green, dried and processed forms. Majority of beans fix nitrogen from the atmosphere, thus contributing significantly to the sustainability of soil fertility in the dry lands, cropping systems and hence reduce the requirements for inorganic fertilizers.Item Grow the Right Maize Variety for Northern Kenya to Get Food and Cash(Kenya Agricultural & Livestock Research Organization (KALRO), 2017) Kimotho, L.M.; Golicha, D.; Kathuli, P.; Kisilu, R.; Maingi, P.M.; Kenya Agricultural and Livestock Research OrganizationMaize is an important commodity in drier areas. If planted on time and on good soil with adequate moisture and fertilizer could provide food and cash for the family. The stover is animal feed especially during the dry period. If produced it could find a ready market.Item KARI-NARL-KSS - Soils of North Horr, their management problems and solutions for improved crops, gums and resins production.(Kenya Agricultural Research Institute, 2008) Muya, E.M ; Lelon, J.K.; Muga, M.; Maingi, P.M.; Kenya Agricultural Research Institute; Kenya Agricultural Research InstituteKenya is an agricultural country, depending almost entirely on land productivity for subsistence and socio-economic development. However, about two-thirds of the country is semi-arid to arid (ASAL). The land cover in the ASAls is generally poor with high degree of land degradation, caused mainly by limited organic inputs required to facilitate the biological processes and ecosystem functions that sustain land productivity. In addition, there is, generally, limited ecosystem capacity to intercept, store and redistribute the rainwater for agricultural production. In the face of rapid population growth and these constraints, it is going to be extremely difficult to maintain sufficiency in foodstuffs in the future. Therefore, an alternative means of survival is required, not only to improve agricultural production, but also to reverse the declining trends in soil productivity, caused by land degradation. Therefore, the main objective of Acacia Operation Project is to rehabilitate the degraded land and enhance its productivity for crops, gums and resins. This is will be achieved by mechanized water harvesting technologies called Delfino and Treno ploughs. The research areas include Sereolipi, Merille, Laisamis, Loglogo and North Horr indicated in location map.Item KARI-NARL-KSS: Assessment of the degree of land degradation and opportunities for improved productivity of Chalbi Desert, 2008(Kenya Agricultural Research Institute, 2008) Muya, E.M.; Maingi, P.M.; Kenya Agricultural Research Institute; Kenya Agricultural Research Institute; Kenya Agricultural Research InstituteKenya is an agricultural country, depending almost entirely on land productivity for subsistence and socio-economic development.

KARI-NARL-KSS(Kenya Agricultural Research Institute, 2001) Muya, E.M.; Ogendo, R.; Mulliei, R.; Maingi, P.M.; Kenya Agricultural Research InstituteThe purpose of the survey was to establish the causes, degree and extent of salinity, sodicity and infertility as well as the influence of the farmers' practices on the problems in Nguruman irrigation scheme. This included the assessment of water quality, existing water uses and certainty of the supply. Soil survey was carried out to delineate the extent and distribution of different soil types, together with their chemical and physical characteristics, particularly those that affect soil-water related properties. The important soil-water related properties studied were: soil depth, water holding capacity,infiltration rate and drainage conditions. In relation to the soil conditions studied, the present farming systems were examined as well as their influence on salinity, sodicity and infertility. The main objective of this study was to derive data on the basis of which to derme appropriate approaches to the solutions of the identified constraints in the irrigation scheme.
