Rendimiento de pasto llorón, Eragrostis curvula (Nees) cv. Ermelo, en función de algunas propiedades edáficas

The relationship between the yield of weeping lovegrass and some edaphic properties of 18 soils in a large area which includes the districts of Bahia Blanca, Villarino, Than and Saavedra in the province of Buenos Aires and the district of Hucal in the province of La Pampa, Argentina, was studied....
