Managing Agricultural Greenhouse Gases: Coordinated Agricultural Research through GRACEnet to Address Our Changing Climate.

1820 An understanding of greenhouse gases (GHGs) associated with agricultural production is a key area of interest in the current scientiic literature due to the potentially negative inluence of agricultural GHGs associated with global climate change. Managing Agricultural Greenhouse Gases focuses on the national GRACEnet project initiated by the USDA–ARS in 2002 and provides a current summary of the research and “state of science,” as described by the authors, resulting from the coordinated research eforts at more than 30 USDA–ARS locations. hese scientists and USDA–ARS locations are widely distributed across the continental United States and thus provide a wide array of information obtained from varied agricultural systems. he book is divided into seven sections, providing extensive information on a wide range of topics ranging from the impacts of no-till crop production in the eastern United States to national economic policy considerations. Section 1 provides supporting details that establish the context for the remainder of the text. he authors provide background information establishing the basis for concerns of anthropogenic GHG emissions, particularly as related to agriculture. Sections 2 and 3 are largely focused on investigating speciic regions in the United States (eastern, central, and western) with a focus on soil organic C dynamics and carbon dioxide, methane, and nitrous oxide response to management, respectively. his organization allows the reader to rapidly access information associated with speciic regional concerns and agricultural production systems in the United States. Section 4 provides detailed reviews of ive models used for estimating soil organic C dynamics and GHG lux, which gives the reader the opportunity to easily compare models. Section 5 details methodology used by GRACEnet scientists for measuring and monitoring agricultural GHGs and discusses Managing Agricultural Greenhouse Gases: Coordinated Agricultural Research through GRACEnet to Address Our Changing Climate
