Producción y calidad de gramíneas en un gradiente de calidades de sitio y coberturas en bosques de Nothofagus antarctica (G. Forster) Oerst. en Patagonia
62-73 The aim of the present study was to quantify the dry matter and crude protein concentration of grasses in different radiation levels and its variation over time, in Nothofagus antarctica (ñire) forests under silvopastoral use growing in contrasting environmental conditions in Southern Patagoni...
