Nesper, MaikeBünemann, Else K.Fonte, Steven J.Rao, Idupulapati M.Velásquez, Jaime E.Ramírez, BerthaHegglin, DjangoFrossard, EmmanuelOberson, Astrid[Pasture degradation decreases organic P content of tropical soils due to soil structural decline]Pasture degradation decreases organic P content of tropical soils due to soil structural decline

Ruminant livestock production in the tropics, particularly when based on pastures, is frequently blamed for being detrimental to the environment, allegedly contributing to: (1) degradation and destruction of ecosystems, including degradation and loss of soil, water and biodiversity; and (2) clima...

Background: Agriculture is the single largest geo-engineering initiative that humans have initiated on planet Earth, largely through the introduction of unprecedented amounts of reactive nitrogen (N) into ecosystems. A major portion of this reactive N applied as fertilizer leaks into the environm...


Subbaraoa, Guntur V.Sahrawat, Kanwar LalNakahara, K.Rao, Idupulapati M.Ishitani, ManabuHash, C.T.Kishi, M.Bonnett, D.Berry, W.Lata, Jean-Christophe[A paradigm shift towards low-nitrifying systems: The role of biological nitrification inhibition (BNI)]A paradigm shift towards low-nitrifying systems: The role of biological nitrification inhibition (BNI)

Agriculture and livestock production systems are two major emitters of greenhouse gases. Methane with a GWP (global warming potential) of 21, and nitrous oxide (N2O) with a GWP of 300, are largely emitted from animal production agriculture, where livestock production is based on pasture and feed ...


Subbaraoa, Guntur V.Rao, Idupulapati M.Nakahara, K.Sahrawat, Kanwar LalHash, C.T.Ando, YasuoKawashima, T.[Potential for biological nitrification inhibition (BNI) to reduce nitrification and N2O emissions from pasture-crop-livestock systems]Potential for biological nitrification inhibition (BNI) to reduce nitrification and N2O emissions from pasture-crop-livestock systems

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...


Karwat, HannesMoreta, DaniloArango, JacoboNúñez, JonathanRao, Idupulapati M.Rincón, ÁlvaroRasche, FrankCadisch, Georg[Residual effect of BNI by Brachiaria humidicola pasture on nitrogen recovery and grain yield of subsequent maize]Residual effect of BNI by Brachiaria humidicola pasture on nitrogen recovery and grain yield of subsequent maize

Low phosphorus (P) supply is a major limitation to pasture establishment and production in highly weathered acid soils. Previous research showed that the forage legume, Arachis pintoi, was more efficient in acquiring P from infertile acid soils than the forage grass, Brachiaria dictyoneura. The m...


Rao, Idupulapati M.Borrero, V.Ricaurte Oyola, José JaumerGarcía, Ramiro[Adaptive attributes of tropical forage species to acid soils. V. Differences in phosphorus acquisition from less available inorganic and organic sources of phosphate]Adaptive attributes of tropical forage species to acid soils. V. Differences in phosphorus acquisition from less available inorganic and organic sources of phosphate

Soil waterlogging reduces gas exchange between the soil and the atmosphere, leading to oxygen deprivation in the rhizosphere. Brachiaria spp. are the most widely sown forage grasses in tropical America. Among commercial Brachiaria grasses, B. humidicola shows superior tolerance to waterlogged soi...

An inter-institutional and multi-disciplinary project to identify Brachiaria genotypes, which combine waterlogging tolerance with high forage yield and quality, for use in agricultural land in Latin America with poor drainage, is underway. The aim is to improve meat and milk production and mitiga...
