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

0104334Matson美国-墨西哥项目资助John Harrison先生在斯坦福大学Pamela Matson博士的指导下进行论文研究。harrison先生将在墨西哥与Ivan ortizi - monasterio博士一起工作，在墨西哥奥布雷贡的国际小麦和玉米改良中心（CYMMYT）开展小麦项目。调查人员将研究墨西哥雅基盆地排水中氧化亚氮的排放。一氧化二氮是一种温室气体，在全球范围内正在增加，而农田施肥被认为是观测到的增加的最重要的单一来源。雅基谷提供了一个独特的机会来观察几种人为变化的相互作用，这些变化是生物地球化学变化的重要驱动因素。本研究的结果将提高我们对农业排水氧化亚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.
