Description
The phosphorus (P) requirements of perennial forage plants adapted to tropical savanna ecosystems are low compared to those of most annual crops or unadapted forage species (Andrew and Jones, 1985; CIAT, 1978). Perrenials are capable of accumulating P in the biomass over time and good pasture management favors micro-environmental conditions which can result in the recycling of P almost independent of the mineral soil (Spain and Salinas, 1985). It has been shown for crops that for maximum fertilizer efficiency at low rates, P should be concentrated near the seed to optimize fertility for seedlings, but there are few data for pastures. Two small plot experiments were conducted to explore fertilizer management options during the establishment and early production phases of two legume-bases pastures.
