1. Nitrogen Transformations in Flooded Agroecosystems: a Case Study with Taro (Colocassia Esculenta)Wetland agriculture covers an estimated 170 million ha and contributes significantly to global food supply. Nitrogen fertilizers are subject to numerous potential transformation pathways in flooded systems. The present research was focused on improving our understanding of N transformations in a flooded agricultural system by addressing the following two broad objectives: 1) determine whether the presence of anammox bacteria and its activity contribute significantly to N losses, and 2) evaluate...

2. An Evaluation of the Effects of Diversified Cropping Systems on Soil Organic Matter, Nutrient Dynamics, Yield and Economics of Dry Land Winter Wheat and Irrigated Sugar Beet in WyomingThe overall objective of this study is to evaluate the effects of different cropping systems and irrigation methods used by Wyoming farmers on soil chemical, biological and physical properties, yield, economic returns and long term ecological sustainability of dryland and irrigated crop production. The Project, which is being carried out on dryland winter wheat systems in the Albin and Slater areas and on irrigated sugar beet systems in the Big Horn basin near Powell, will go... J. Norton, E.
