Collaborative Research: Soil Organic Matter Dynamics in the Tropics: Determinants and Consequences

开展热带土壤有机质先导研究。在秘鲁尤里马苏亚斯和其他几个热带农业地点进行的实地研究将提供土壤有机质动态数据。其中一些数据将被用来修改为温带农业生态系统开发的土壤有机模型，以便将其用于热带地区。其余的数据将用于验证修改后的模型。该模型是土壤生物学和化学中当前思维的前沿综合。它在热带土壤问题上的应用将提供热带土壤迄今未综合的信息及其对管理的响应的迫切需要的集成。有了这个综合工具，我们应该能够更好地管理热带地区往往脆弱的土壤。参与试点研究的研究人员都是世界公认的各自领域的专家。近20年来，桑切斯博士已经证明了他在拉丁美洲偏远野外环境中工作的能力。北卡罗来纳州立大学和科罗拉多州立大学的机构支持非常好。

A pilot study of tropical soil organic matter will be conducted. Field studies being conducted in Yurimaguas, Peru and in several other tropical agricultural sites will provide data on soil organic matter dynamics. Some of these data will then be used to modify a soil organic model developed for temperate zone agroecosystems so that it can be used in the tropics. The remainder of the data will be used to validate the modified model. The model is a cutting-edge synthesis of current thinking in soil biology and chemistry. Its application to tropical soils problems will provide much need integration of here-to-fore unsynthesized information on tropical soils and their responses to management. With this synthesis tool we should be better able to manage the often fragile soils of the tropics. The investigators involved in the pilot study are world- recognized experts in their respective fields. Dr. Sanchez has demonstrated, for almost two decades, his ability to work in remote field settings in Latin America. Institutional support at North Carolina State University and Colorado State University are excellent.
