| 1 | Strategies for farmers and policy makers to control nitro-gen losses whilst maintaining crop production显示文摘The nitrogen (N) cycle is essentially 'leaky'. The losses of small amounts of nitrate to waters and of ammonia and nitrous oxide to the atmosphere are a part of the global biogeochemical N cycle. However, intensive agricultural production, industry and vehicle use have more tem change and health concerns. Research has identified agricultural practices that cause large losses of N and, in some cases, developed solutions. This paper discusses the problems of maintaining productivity while reducing N losses, compares conventional with low input (integrated) and organic farming systems, and discusses wider options. It also looks at the need to integrate studies on N with other environmental impacts, set in the context of the whole farm system, to provide truly sustainable agricultural systems. | Keith W.T.Goulding | 2005 | Science China(Life Sciences)2005，48，z2： | 1 |
| 2 | 耕作和混合农业体系未来植物养分利用的前景和挑战显示文摘在不污染环境的情况下生产足量的健康食品对未来世界农业是一个严重挑战。瑞典'21世纪的食物'研究计划已经研究了可持续耕作体系的经济的、环境的以及社会的各个方面,本文列举了瑞典'21世纪的食物'研究计划以及其它相关的国际研究计划中注重改善养分利用效率的一些研究,特别是氮和磷。它表明有许多可持续性解决养分利用效率的方法,有些很复杂,但有些就很简单。政府政策包括津贴、研究和技术以及公众对耕作方式的认可,所有这些都与制定这些解决方法结合在一起。需要知识转让的参与式途径,这样科学家、政策决策者、农场主、顾问以及消费者们可以交流信息,一起构建可持续的耕作体系。 | Lars Bergstrm Keith W.T.Goulding 张秋英 | 2005 | AMBIO-人类环境杂志2005，34，4： | 0 |
