U.S. Mexico Dissertation Research: Nitrogen Cycling and Nitrous Oxide Emissions from Waters Draining the Yaqui Basin, Mexico

0104334马特森美国-墨西哥项目奖将为约翰·哈里森先生在斯坦福大学的帕梅拉马特森博士的指导下进行的论文研究提供支持。 Harrrison先生将与Ivan Ortiz-Monteo博士一起在墨西哥奥布拉的国际小麦和玉米改良中心（CYMMYT）的小麦项目上工作。 调查人员将研究墨西哥亚基盆地沃茨排放的一氧化二氮。一氧化二氮是一种温室气体，在全球范围内不断增加，农田施肥被认为是观察到的增加的唯一最重要来源。 亚基河谷提供了一个独特的机会，可以观察几种人为变化的相互作用，这些变化是地球化学变化的重要驱动因素。这项研究的结果应该提高我们对农业排水中一氧化二氮排放及其控制因素的基本认识。

0104334MatsonThis U.S.-Mexico Program award will provide support for dissertation research by Mr. John Harrison, under the direction of Dr. Pamela Matson of Stanford University. Mr. Harrrison will work in Mexico with Dr. Ivan Ortiz-Monasterio on the Wheat Program at the International Wheat and Maize Improvement Center (CYMMYT) in Obregon, Mexico. The investigators will study the emissions of nitrous oxide from waters draining the Yaqui Basin in Mexico. Nitrous oxide is a greenhouse gas that is increasing globally and the fertilization of agricultural fields is thought to be the single most important source of the observed increase. The Yaqui Valley provides a unique opportunity to look at the interactions of several kinds of anthropogenic change that are important drivers of biogeochemical change. Results from this study should improve our basic understanding of nitrous oxide emissions from agricultural drainage and the factors that control them.
