Description
Natural pastures in large areas of Uruguay can be improved by fertilization with phosphorus (P) and surface sowing of adapted legumes, promoting an increased forage production and quality, with the consequent higher carrying capacity and better animal performance. A study was conducted to evaluate two improved grasslands with two stocking rates under rotational grazing. Such improvements resulted from the oversowing of: 1) white clover (Trifolium repens) plus birdsfoot trefoil (Lotus corniculatus); and 2) annual lotus (Lotus subbiflorus). In these pastures, with important presence of legumes, a higher frequency of C3 and winter species, high levels of animal production were registered during the first two years of evaluation, showing the potential of this technology.
