Aerobic mineralization and recovery of nitrogen as affected by soil organic matter status in three sites in Kenya

Karunditu, M.W.; Mugendi, D.N.; Kung'u, J.B.; Vanlauwe, B. (The Soil Science Society of East Africa National Research Laboratories, 2005)

Pressure on available land has increased due to high population density and other competing land-use demands which have led to reduced use of traditional fallows and subsequent decline in soil fertility. Aerobic Nmi ...

Adaptation Mechanisms to Curb the Impacts of Climate (rainfall and temperature) Variability

Mucheru-Muna, M.; Mugwe, J. N.; Ngetich, F.; Mugendi, D.N.; Mairura, F.; Mugi, Esther (Regional Universities Forum for Capacity Building in Agriculture (RUFORUM), 2014)

Smallholder farmers in Tharaka and Kitui suffer the adverse effects of climate variability, especially variations in rainfall and temperatureThis has had a negative impact on agricultural production and is attributed to ...

Organic residue effects on soil physical and chemical properties in Kenya

Mugendi, D.N.; Waswa, B. N.; Vanlauwe, B.; Nandwa, S.; Kung'u, J.B. (The Soil Science Society of East Africa National Research Laboratories, 2005)

This study was designed to evaluate the influence of organic resource management on selected soil chemical properties in central and western highlands of Kenya. Three ongoing experiments (Kabete, Masenoand Embu) ...

Nursery media effects on tamarindus indica seedling establishment

Kung'u, J.B.; Kihara, J.; Jaenicke, H.; Mugendi, D.N. (The Soil Science Society of East Africa National Research Laboratories, 2005)

Trees are an important component of farming systems and contribute to human needs both directly through tree products andindirectly through their influence in soil fertility. Efforts by small-scale farmers to increase ...

The effect of education levels in dissemination of soil fertility management practices in the central highlands of Kenya

Mucheru-Muna, M.; Kimaru-Muchai, S. W.; Mugwe, J. N.; Kimemia, J. N.; Mugendi, D.N.; Macharia, J. M. (2011)

Inadequate links between researchers and farmers has resulted in a pitiful lack of take-up of research advances recommended to improve food security in the central highlands of Kenya. Access to timely and accurate information ...

Nitrogen uptake and use efficiency as affected by soil organic matter status in Embu, Kabete and Maseno, Kenya

Mugendi, D.N.; Karunditu, M. W.; Kung'u, J.B.; Vanlauwe, B. (2003)

Nitrogen (N) is the nutrient most limiting to crop production and effective management is inevitable to minimizeits losses through the many pathways. Nitrogen uptake and use efficiency as affected by soil organic matter ...

Use of leguminous shrubs for soil fertility improvement in sub-humid highlands of Kenya

Mugwe, J. N.; Mugendi, D.N. (2006)

Declining crop productivity is a major challenge facing smallholder farmers in central highlands of Kenya. This decline is caused by continuous cultivation of soils without adequate addition of external inputs in form of ...

The Role of Indigenous Knowledge in Management of Soil Quality among Smallholders in Chuka and Gachoka Divisions, Kenya

Mairura, F. S; Mugendi, D.N.; Mwanje, J. I.; Ramisch, J. J.; Mbugua, P. K. (Kenpak Colour Printers, 2005)

Scientists and farmers possess qualitative knowledge of agro-ecosystems that they observe, which could be a valuable resource for science. A study based on participatory methods was conducted to determine farmers' soil ...
