Production improvement through phosphorus fertilization and legume introduction in grazed native pastures of Uruguay

Abstract: The objective of the current study was to quantify the response of pasture to phosphorus (P) fertilizer application and legume introduction, by measuring herbage yield, nitrogen (N) and P content, and weight gain of calves in native pastures of Uruguay. Quantitative relationships between pasture characteristics and post-weaning daily live weight gain (DLWG) were also examined. The treatments studied were native grassland (NG) and improved pasture, oversown with Lotus corniculatus L. and Trifolium repens L. wit… Show more

“…Another option to overcome the limitations of native grasslands is overseeding legumes, mainly Lotus sp. and Trifolium sp., combined with P fertilization (Del Pino et al, 2016;Jaurena et al, 2016), or overseeding annual grasses, mainly Lolium multiflorum, combined with N fertilization (Ferreira et al, 2011a;Brambilla et al, 2012), or a mix of legumes and grasses and N and P fertilizers (Oliveira et al, 2015). These technologies are effective strategies to establish productive, high-quality C3 forage species into native grasslands that could be used to reduce seasonality and increase animal performance and stocking rates.…”

“…El estudio se realizó en el Departamento de Salto, Uruguay (31º 14' S, 57º 08' O), en un sitio donde se llevó a cabo entre 1995 y 2002 un experimento que tuvo como objetivo la cuantificación del efecto de la fertilización fosfatada y la introducción de leguminosas sobre la calidad de las pasturas y su relación con la producción de carne de los animales en pastoreo (del Pino et al, 2015). Este experimento se instaló sobre un suelo profundo desarrollado sobre materiales derivados de basalto, siendo los parámetros del horizonte A: densidad aparente: 1,1 g cm -3 ; pH: 5,7; C orgánico: 34,8 g kg -1 ; N orgánico: 0,36 %; P Bray N.º 1: 4 mg kg -1 ; óxidos de Fe: 1,8 %.…”
