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...


Delve, Robert J.Cadisch, GeorgTanner, J.C.Thorpe, W.R.Thorne, Peter J.Giller, Ken E.[Implications of livestock feeding management on soil fertility in the smallholder farming systems of sub-Saharan Africa]Implications of livestock feeding management on soil fertility in the smallholder farming systems of sub-Saharan Africa
Towett, Erick K.Shepherd, Keith D.Tondoh, Jérôme E.Winowiecki, Leigh A.Tamene, LulsegedNyambura, MercySila, AndrewVågen, Tor-GunnarCadisch, Georg[Total elemental composition of soils in Sub-Saharan Africa and relationship with soil forming factors]Total elemental composition of soils in Sub-Saharan Africa and relationship with soil forming factors

There exists a considerable knowledge gap about the effect of biochemical quality of organic inputs and their combination with inorganic N on abundance and community composition of ammonia-oxidizing archaea (AOA) and bacteria (AOB). Here, we investigated in a Humic Nitisol of 10-year old field ex...


Muema, E.K.Cadisch, GeorgRohl, C.Vanlauwe, BernardRasche, F.[Response of ammonia-oxidizing bacteria and archaea to biochemical quality of organic inputs combined with mineral nitrogen fertilizer in an arable soil]Response of ammonia-oxidizing bacteria and archaea to biochemical quality of organic inputs combined with mineral nitrogen fertilizer in an arable soil

Knowledge of soil spatial variability is important in natural resource management, interpolation and soil sampling design, but requires a considerable amount of geo-referenced data. In this study, mid-infrared spectroscopy in combination with spatial analyses tools is being proposed to facilitate...

Organic resources (ORs) are essential inputs in tropical farming systems and their decomposition dynamics are related to their quality. A Decision Support System (DSS) for organic N management has been proposed earlier that subdivides ORs in four classes depending on their N, lignin, and soluble ...

Load estimates are more informative than constituent concentrations alone, as they allow quantification of on- and off-site impacts of environmental processes concerning pollutants, nutrients and sediment, such as soil fertility loss, reservoir sedimentation and irrigation channel siltation. Whil...

Maintaining indigenous nutrient supply and positive nutrient balances are key factors in sustaining rice yields. Irrigation systems act as conveyers for water, sediments and nutrients throughout landscapes, especially in mountainous, cultivated tropical areas where erosivity is usually high. Cont...

Composite agricultural systems with permanent maize cultivation in the uplands and irrigated rice in the valleys are very common in mountainous southeast Asia. The soil loss and fertility decline of the upland fields is well documented, but little is known about reallocation of these sediments wi...
