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

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...

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...
