Description

Native pastures in Portugal have relatively low productivity. The yield and botanical composition of such grasslands, where some legumes species are present, can be improved by fertilization with phosphorus application and/or also liming (Carter, 1983). The presence of legumes in pasture can also be improved by molybdenum application (Lattan et al., 1984). Significant increases of phosphorus concentration in plants (Garden et al., 1978) and on soil available phosphorus (Gregan et al., 1980) due to phosphorus application have also been reported.

The objectives of this study were to evaluate the potential of such treatments on the improvement of native pastures.
