Phosphorus transformations in an oxisol under contrasting land-use systems: The role of the soil microbial biomass

Autor: Oberson, Astrid Friesen, Dennis K. Rao, Idupulapati M. Buhler, S Frossard, Emmanuel

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...

Sequential phosphorus extraction of a 33P-labeled oxisol under contrasting agricultural systems

Autor: Buehler, S. Oberson, Astrid Rao, Idupulapati M. Friesen, Dennis K. Frossard, Emmanuel

Chemical sequential extraction is widely used to divide soil phosphorus (P) into different inorganic (Pi) and organic (Po) fractions, but the assignment of these fractions to pools of differing plant availability, especially for low P tropical soils, is still matter of discussion. To improve this...

A comparative study on plant growth and root plasticity responses of two Brachiaria forage grasses grown in nutrient solution at low and high phosphorus supply

Autor: Louw-Gaume, A Rao, Idupulapati M. Gaume, A Frossard, Emmanuel

Brachiaria forage grasses are widely used for livestock production in the tropics. Signalgrass (Brachiaria decumbens cv. Basilisk, CIAT 606) is better adapted to low phosphorus (P) soils than ruzigrass (B. ruziziensis cv. Kennedy, CIAT 654), but the physiological basis of differences in low-P ada...
