Efecto de Fuentes de Azufre Sobre el Rendimiento y Calidad de Trigo y Pradera en Dos Andisoles

Two experiments were carried out to evaluate the effect of source and rate of sulphur (S) on yield and quality of a wheat (Triticum aestivum L.) crop and a permanent naturalized pasture in southern Chile. In the wheat trial, calcium sulphate (SCA) and magnesium sulphate (SMG) were tested (45 and 90...
