Over many decades there has been a global trend away from mixed farming and integrated crop-livestock systems to more-intensive single commodity systems. This has distorted local and global nutrient balances, resulting in environmental pollution as well as soil nutrient depletion. Future food systems should include integrated crop-livestock systems with tight nutrient budgets. For nitrogen (N), detailed understanding of processes, fluxes ? including of gaseous forms ? and budgets at a component level is needed to design productive systems with high N use efficiency (NUE) across the full nutrient chain. In Uruguay, a unique rice-livestock system has been practiced for over 50 years, attaining a high production level for rice (mean grain yields > 8 Mg ha?1) and an average level for livestock (120 kg liveweight gain ha?1 y?1). The aim of this study was to quantify the components of the N balance and NUE of this system, so as to understand its long-term sustainability, and draw conclusions for other regions. Analysis of country-level statistics for each component over the last 16 years shows tight N balances of +3.49, +2.20 and +2.22 kg N ha?1 yr?1 for rice, livestock and the whole system, respectively. Based on average values of N retained in edible food products, NUE values were 65.7, 13.2 and 23.1% for rice, livestock and the whole system, respectively. While NUE of livestock was unchanged over the period, NUE of the rice component decreased due to increasing fertiliser use. Further gains in N efficiency are possible by better integrating the system components. Actions to increase system level NUE include raising pasture and livestock productivity and controlling the increasing use of N fertilisers in rice. Tightly integrated crop-livestock systems can play a significant role in re-shaping global agriculture towards meeting food security, environmental and socioeconomic sustainability targets.

Contenido : |
Las presentaciones realizadas describieron distintos aspectos que han sido investigados en estos últimos años en Uruguay, Brasil y Argentina. La investigación desarrollada apuntó en primer lugar a conocer la biología y el comportamiento de esta nueva plaga. A partir de ese conocimiento se desarrollaron estrategias de manejo. En la jornada se presentó el estado del arte en lo referente al control biológico con la avispa parasitoide Cleruchoides noackae, el desarrollo de un biopesticida a base de hongos entomopatógenos, haciendo hincapié en los procesos de escalamiento. También se discutió el uso potencial de semioquímicos en el manejo de esta plaga. |
