Track 2-3-2: Impact of Grass and Legumes on Livestock Production, Soil Conservation and the Nitrogen Cycle in Grassland and Forage Ecosystems
Description
In Chile, the livestock systems based on perennial swards (grasses/white clover) have intensified its production because of the indiscriminated increases in nitrogen fertilization (Vistoso et al., 2012). Currently, new agronomic practices are demanded to allow the increase of the Nitrogen Use Efficiency (NUE) of perennial swards. In livestock systems, NUE can be studied and improved at animal, soil and plant level. In Chile, the two first levels have been broadly studied (Vistoso et al., 2012) but the plant contribution has been ignored. Today, a lot of cultivars from temperate grass species originated from different part of the world are commercialized in Chile. The objective of this work was to evaluate the NUE of four perennial forage grasses species and to determinate the role of the root system.
