Amézquita Collazos, EdgarRao, Idupulapati M.Rivera, M.Corrales, I.I.Bernal Riobo, Jaime Humberto[Sistemas agropastoriles: un enfoque integrado para el manejo sostenible de oxisoles de los Llanos Orientales de Colombia]Sistemas agropastoriles: un enfoque integrado para el manejo sostenible de oxisoles de los Llanos Orientales de Colombia

High nitrogen (N) concentration in bovine urine, which generally exceeds plant N uptake rates, results in the formation of hotspots of N loss when bovine urine is deposited on grazed pasture soils. High spatial variability in the distribution of urine patches in grazed pastures poses a major chal...


Byrnes, Ryan C.Nùñez, JonathanArenas-Calle, Laura N.Rao, Idupulapati M.Trujillo, CatalinaÁlvarez, CarolinaArango, JacoboRasche, FrankChirinda, Ngonidzashe[Biological nitrification inhibition by Brachiaria grasses mitigates soil nitrous oxide emissions from bovine urine patches]Biological nitrification inhibition by Brachiaria grasses mitigates soil nitrous oxide emissions from bovine urine patches

It is generally assumed that phosphorus (P) availability for plant growth on highly weathered and P-deficient tropical soils may depend more on biologically mediated organic P (Po) turnover processes than on the release of adsorbed inorganic P (Pi). However, experimental evidence showing the link...

Regulating nitrification could be a key strategy in improving nitrogen (N) recovery and agronomic N-use efficiency in situations where the loss of N following nitrification is significant. A highly sensitive bioassay using recombinant luminescent Nitrosomonas europaea, has been developed that can...

Belowground (BG) plant resource allocation, including roots and rhizodeposition, is a major source of soil organic matter. Knowledge on the amounts and turnover of BG carbon (C), nitrogen (N), and phosphorus (P) in soil is critical to the understanding of how these elements cycle in soil-plant sy...
