Egenolf, KonradKarwat, HannesRasche, FrankCadisch, GeorgMoreta, DaniloArango, JacoboRao, Idupulapati M.[Impact of "Biological Nitrification Inhibition"on N recovery efficiency, N leaching and N2O emissions using the example of brachiaria humidicola]Impact of "Biological Nitrification Inhibition"on N recovery efficiency, N leaching and N2O emissions using the example of brachiaria humidicola

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
Moreta, D.E.Arango, JacoboSotelo, M.Vergara, D.Rincón, A.Ishitani, ManabuCastro, A.Miles, John W.Peters, MichaelTohme, Joseph M.Subbaraoa, Guntur V.Cadisch, GeorgRao, Idupulapati M.[Using biological nitrification inhibition as a strategy to improve nitrogen recovery and nitrogen use efficiency of agricultural systems and to mitigate climate change]Using biological nitrification inhibition as a strategy to improve nitrogen recovery and nitrogen use efficiency of agricultural systems and to mitigate climate change

Tropical forage grasses and legumes as key components of sustainable crop-livestock systems in Latin America and the Caribbean have major implications for improving food security, alleviating poverty, restoring degraded lands and mitigating climate change. Climate-smart tropical forage crops can ...

Four inoculated ecotypes of each of Centrosema acutifolium, C. brasilianum and C. macrocarpum were grown in undisturbed soil (oxisol) cores in a glasshouse to study their response to 7 phosporus levels (a total of 11, 22, 45, 90, 180, 360 and 720 mg/core P, surface applied as Ca(H2PO4)2.H2O). Sev...

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 ...

Due to inadequate feed supplies for livestock production, farmers throughout the tropics and sub-tropics are being encouraged to supplement low quality basal diets with leguminous forage and concentrates. The varying quality (e.g. nitrogen, lignin and polyphenol content) of these diets will influ...
