Adaptive attributes of tropical forage species to acid soils. V. Differences in phosphorus acquisition from less available inorganic and organic sources of phosphate

Autor: Rao, Idupulapati M. Borrero, V. Ricaurte Oyola, José Jaumer García, Ramiro

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...

Simulating phosphorus responses in annual crops using APSIM : Model evaluation on contrasting soil types

Autor: Delve, Robert J. Probert, ME Cobo Borrero, Juan G. Ricaurte Oyola, José Jaumer Rivera Pena, M Barrios, E. Rao, Idupulapati M.

Crop simulation models have been used successfully to evaluate many systems and the impact of change on these systems, e.g. for climatic risk and the use of alternative management options, including the use of nitrogen fertilisers. However, for low input systems in tropical and subtropical region...

Adaptive attributes of tropical forage species to acid soils. III. Differences in phosphorus acquisition and utilization as influenced by varying phosphorus supply and soil type

Autor: Rao, Idupulapati M. Borrero, V. Ricaurte Oyola, José Jaumer García, Ramiro Ayarza, Miguel Angel

Low phosphorus (P) supply is a major limitation of forage production in acid soils of the tropics. A glasshouse experiment was conducted to determine the differences in P acquisition and utilization among three legumes (Arachis pintoi, Stylosanthes capitata and Centrosema acutifolium) and one gra...

Journal Article 2000

Distribución radicular, absorción de nutrientes y erosión edáfica en sistemas de cultivos y forrajes en laderas del Cauca, Colombia = Roots distribution, nutrient absorption and soils erotion in forage and crops systems in Cauca hillside (Colombia)

Autor: Ricaurte Oyola, José Jaumer Zhiping Qui Filipe, D Rao, Idupulapati M. Amézquita Collazos, Edgar

Los procesos erosivos en laderas Andinas (evidentes con la presencia de calvas, procesos de soliflucción, cárcavas, etc.) limitan el crecimiento de las plantas y, con ello, las posibilidades de sustentar una población humana creciente en la región. Los sistemas de producción tradicionales involu...

Autor: Ricaurte Oyola, José Jaumer Rao, Idupulapati M. Menjivar Flores, JC

En un Haplustox de los Llanos Orientales de Colombia se evaluaron durante 41 meses 6 genotipos de Brachiaria con resistencia variable a niveles altos de Al+3 en dos niveles de nutrientes. Los genotipos con resistencia media y alta mantuvieron altas producciones de biomasa aérea en los primeros me...
