Interactions between sulfur, nitrogen, and iron cycles in the sustainable management and use of acid sulfate soils.

硫、氮和铁循环在硫酸土壤可持续管理和利用中的相互作用。酸性硫酸盐土壤（ASS）会引起重大的土地管理和环境问题。有人提出，硫、氮和铁生物地球化学循环之间的联系决定了与使用ASS相关的环境和作物生产危害。为了制定ASS的最佳管理做法，重要的是研究这些联系并确定它们对从这些土壤输出的物质通量的贡献。本项目将进行这方面的研究，并将成果转让给工业伙伴，以改善土地管理做法，并在亚洲生态系统景观中确定适当的土地用途。

Interactions between sulfur, nitrogen, and iron cycles in the sustainable management and use of acid sulfate soils. Acid Sulfate Soils (ASS) can cause major land management and environmental problems. It has been proposed that the linkages between the Sulfur, Nitrogen, and Iron biogeochemical cycles deterrmine the environmental and crop production hazards associated with use of ASS. In order to develop best management practices for ASS, it is important to research those linkages and determine their contribution to fluxes of materials exported from these soils. This project will carry out that research and will transfer results to industry partners to improve land management practices and identify appropriate landuses in ASS landcapes.
