      G. M, Mwenda; N.K, Karanja; H., Boga; J.H.P, Kahindi; A, Muigai; D, Odee (Jomo Kenyatta University of Agriculture and TechnologyUnited States International UniversityKenya Forestry Research InstituteDepartment of Land Resource Management & Agricultural Technology, University of Nairobi, Kenya, 2011)
      A major strategy towards addressing soil fertility depletion is the conservation and sustainable use of rhizobia that are able to fix nitrogen in the soil in association with legumes. The study assessed abundance and ...
    • Evaluating effect of mixtures of organic resources on nutrient release patterns and uptake by maize 

      F.O, Ayuke; N.K, Karanja; S.W, Bunyasi (SpringerDepartment of Soil Science, College of Agriculture and Veterinary Medicine, University of NairobiDepartment of Applied Biology, Faculty of Science, Kenya Methodist UniversityCoffee Research Foundation (CRF), Sagana, Kenya, 2007)
      To supplement high costs of inorganic fertilizers, smallholder farmers in the tropics are likely to increase the use of appropriate plant residues as an alternative source of plant nutrients especially nitrogen (N) and ...
    • Legume Based Cropping and Soil Biodiversity Dynamics 

      N.K, Karanja; J.M, Kimenju; A.O, Esilaba; J., Jefwa; F, Ayuke (Springer Science+Business MediaDepartment of Land Resource Management and Agricultural TechnologyDepartment of Plant Science and Crop Protection, University of NairobiKenya Agricultural Research Institute (KARI), Headquarters,CIAT-Tropical Soil Biology and Fertility, 2011)
      The soil is home to an enormous diversity of organisms, many of which are beneficial, while a small and equally diverse proportion contains harmful organisms. Legume cropping and husbandry practices impact negatively or ...
