Nitrification, a key process in the global nitrogen cycle that generates nitrate through microbial activity, may enhance losses of fertilizer nitrogen by leaching and denitrification. Certain plants can suppress soil-nitrification by releasing inhibitors from roots, a phenomenon termed biological...

Established swards of the tropical forage grass Andropogon gayanus var. bis-quamulatus (Hochst.) Hack were heavily colonized by the leaf-cutter Acromyrmex landolti Forel over a period of 33 months in the eastern plains of Colombia. Density of Ac. landolti colonies in swards of A. gayanus increase...

An in vitro experiment was performed to compare the forage quality of foliage of Calliandra (Calliandra calothyrsus Meissner var. Patulul) cultivated on either low or medium-fertility soils in Colombia and Kenya, respectively. A grass-alone diet, with and without urea supplementation, and five le...

Tesis (M.Sc.)]Caracterizacion de la resistencia de Brachiaria spp. al salivazo de los pastos Zulia Colombiana (Lallemand) (Homoptera:Cercopidae). Tesis (M.Sc.)

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...

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...
