Implications of livestock feeding management on soil fertility in the smallholder farming systems of sub-Saharan Africa

Autor: Delve, Robert J. Cadisch, Georg Tanner, J.C. Thorpe, W.R. Thorne, Peter J. Giller, Ken E.

The role of livestock in nitrogen cycling in mixed crop-livestock farming systems of sub-Saharan Africa was explored. Cattle were fed a range of diets to investigate the effects on partitioning of nitrogen between urine and faeces and on the chemical composition of the manures produced. The trade...

Harvesting management options for legumes intercropped in napier grass in the central highlands of Kenya

Autor: Mwangi, D.M. Cadisch, Georg Thorpe, W.R. Giller, Ken E.

Ways of promoting integration of herbaceous forage legumes into a napier grass fodder system were evaluated with the aim of increasing forage quantity and quality on smallholder dairy farms in central Kenya. The herbaceous legumes Desmodium intortum cGreenleaf (ILRI 104), Macrotyloma axillare cAx...

Lasting influence of biochemically contrasting organic inputs on abundance and community structure of total and proteolytic bacteria in tropical soils

Autor: Rasche, F. Musyoki, M.K. Röhl, C. Muema, E.K. Vanlauwe, Bernard Cadisch, Georg

The SOM field experiments in Kenya, which have been initiated in 2002 on two contrasting soils (clayey Humic Nitisol (sand: 17%; silt: 18%; clay: 65%) at Embu, sandy Ferric Alisol (sand: 66%; silt: 11%; clay: 22%) at Machanga), were used for exploring the effect of nine year annual application of...

Tillage and varietal impacts on tomato (Solanum lycopersicum L.) production on an ultisol in central Cameroon

Autor: Tueche, J. Norgrove, L. Hauser, S. Cadisch, Georg

Across Africa the production of high value horticultural crops is being recognized as a possible route out of rural poverty. To determine at which level of intensification tomato yields were maximized and which tomato cultivar responds best to intensification, an on-farm, factorial trial was cond...

Nitrate reductase activity in leaves as a plant physiological indicator of in vivo biological nitrification inhibition by Brachiaria humidicola

Autor: Karwat, Hannes Sparke, Marc-André Rasche, Frank Arango, Jacobo Nuñez, Jonathan Rao, Idupulapati M. Moreta, Danilo Cadisch, Georg

The tropical forage grass Brachiaria humidicola (Bh) controls soil microbial nitrification via biological nitrification inhibition (BNI). The aim of our study was to verify if nitrate reductase activity (NRA) in Bh roots or leaves reflects in vivo performance of BNI in soils. NRA was measured in ...

Biological nitrification inhibition activity in a soil-grown biparental population of the forage grass, Brachiaria humidicola

Autor: Nuñez, Jonathan Arévalo, Ashly Karwat, Hannes Egenolf, Konrad Miles, John W. Chirinda, Ngonidzashe Cadisch, Georg Rasche, Frank Rao, Idupulapati M. Subbarao, Guntur Arango, Jacobo

Aim: Utilization of biological nitrification inhibition (BNI) strategy can reduce nitrogen losses in agricultural systems. This study is aimed at characterizing BNI activity in a plant-soil system using a biparental hybrid population of Brachiaria humidicola (Bh), a forage grass with high BNI pot...

Residual effect of BNI by Brachiaria humidicola pasture on nitrogen recovery and grain yield of subsequent maize

Autor: Karwat, Hannes Moreta, Danilo Arango, Jacobo Núñez, Jonathan Rao, Idupulapati M. Rincón, Álvaro Rasche, Frank Cadisch, Georg

Background and Aims: The forage grass Brachiaria humidicola (Bh) has been shown to reduce soil microbial nitrification. However, it is not known if biological nitrification inhibition (BNI) also has an effect on nitrogen (N) cycling during cultivation of subsequent crops. Therefore, the objective...

Low 15N Natural Abundance in Shoot Tissue of Brachiaria humidicola Is an Indicator of Reduced N Losses Due to Biological Nitrification Inhibition (BNI)

Autor: Karwat, Hannes Egenolf, Konrad Nuñez, Jonathan Rao, Idupulapati M. Rasche, Frank Arango, Jacobo Moreta, Danilo Arévalo, Ashly Cadisch, Georg

The tropical forage grass Brachiaria humidicola (Bh) suppresses the activity of soil nitrifiers through biological nitrification inhibition (BNI). As a result, nitrate (NO−3) formation and leaching are reduced which is also expected to tighten the soil nitrogen (N) cycle. However, the beneficial ...
