“…Best Management Practices (BMPs) are widely recognized as effective measures in reducing NPS pollution in agricultural watersheds (Beegle et al, 2000). These practices, including structural and non-structural, are developed to achieve a sustainable balance between water quality protection and economic development within a watershed under natural and economic limitations.…”

Understanding the impacts of global climate change on the spatiotemporal pattern of hydrologic cycle and water resources is of major importance in highly developed watersheds all over the world. These impacts are strongly dependent on related changes in intensity and frequency of extreme climate events. Implementation of Best Management Practices (BMPs) and policy approaches at watershed and regional scales is essential for mitigating their negative impacts on soil and water conservation, and sustainable economic development. However, the uncertainty of BMP effectiveness including increasing variability of future water supply and changing magnitudes of nonpoint source pollution has to be accounted for in watershed planning and management. This paper provides a review and discussion on the impacts of global climate change on BMP's hydrologic performance, the current progress on hydrologic assessment of BMPs, as well as the existing problems and countermeasures. Research challenges and opportunities in the field of hydrologic assessment of BMPs under global climate change are also discussed in this paper.

“…Plans vary in complexity, form, and level of detail. At their most basic level, NMPs document available nutrient sources on a farm and specify the amounts of manure and additional commercial nutrients to be applied on each field (Beegle et al 2000;Shepard 2005). Developing a NMP involves soil testing, identifying environmentally sensitive areas, and calculating nutrient availability and crop needs.…”

“…Unlike those structural practices that can be monitored for use and maintenance, NM is largely a set of behaviors that is difficult to observe. Even when NMPs are recorded with conservation agencies, producers face challenges implementing prescribed actions on their operations (Beegle et al 2000;Cabot et al 2006;Pierce et al 2007 This study helps address the dual challenges of understanding use of NM practices and the impacts of training programs that seek to improve those practices. The purpose of this study is to identify behavioral changes and perceived impacts of NM among farmers following their participation in a NM educational workshop program.…”

Even when NMPs are recorded with conservation agencies, producers face challenges implementing prescribed actions on their operations (Beegle et al 2000;Cabot et al 2006;Pierce et al 2007). Conservationists recognize the need for better monitoring and tracking of practices and to combine social data with physical data to better understand impacts on environmental conditions (Ambs 2007;Jackson-Smith et al 2010;Lambert et al 2007;Nowak and Cabot 2004;Sylvester and Redman 2007 This study helps address the dual challenges of understanding use of NM practices and the impacts of training programs that seek to improve those practices.…”

Abstract:The importance of nutrient management plans (NMPs) in mitigating the impact of farm-based nutrient applications on the environment is widely acknowledged. However, despite years of promotion by agencies, most farmers still have not developed a NMP. Those plans that have been developed vary in quality and in the degree to which they are actually implemented. Although effective tools have emerged to aid plan development, the planning process remains time and resource intensive. In addition, information about NMPs and actual nutrient application rates generally is not available to resource managers who address water quality issues. This study examines changes in nutrient management behaviors and perceptions among 259 farmers, who participated in a multisession educational workshop series focused on understanding and developing NMPs. Based on structured interviews with farmers before and again one to three years after the workshops, the study finds that farmers are developing NMPs, understanding their plans, and also changing nutrient application rates (both increasing and decreasing). After implementing their NMPs, a strong majority (69%) of the participants believe that their plan has saved them money with no negative effect on yield. Three main findings hold implications for broader water quality and land conservation programs: (1) NMP education courses can lead to changes in farmer nutrient management behaviors, not always toward reducing nutrients; (2) farmers acknowledge challenges in fully implementing their plans, yet a high percentage (82%) indicate that they follow their plan on most (>76%) of their land; and (3) there is a need for accessible approaches to measure and track nutrient management behaviors separate from NMPs and in cases where they do not exist. Key words: adoption-behavior change-evaluation-nutrient management planningprogram evaluation-workshopsNonpoint source (NPS) pollution from agricultural nutrients is recognized as the largest contributor to poor water quality throughout many regions of the United States (USEPA 2009; USGS 2010). Nonpoint source pollution from rural and urban landscapes carries nutrients and other contaminants into surface water and groundwater and contributes to tainted drinking water supplies, degraded fish and wildlife habitat, and compromised recreational opportunities. For decades, numerous federal, state, and local agencies and nongovernmental organizations have provided technical assistance, funding, oversight, and expertise to enable landowners to use practices aimed at minimizing the impact of NPS (Osmond 2010; Duriancik et al. 2008).Despite those efforts, substantial challenges remain, and reducing agricultural nutrient loads is a central component for many water quality restoration and protection strategies (USEPA 2008;Thomas et al. 2007;Diebel et al. 2008;Jha et al. 2010).Agricultural nutrient management plans (NMPs) provide a means for balancing crop nutrient needs with potential environmental quality impacts, and they are widely promoted.

Abstract. This chapter reviews nutrient management of intensively managed grasslands used for dairy farming in The Netherlands, with emphasis on research but with linkages to practice. Firstly, it provides an overview of the changes that have taken place in nutrient management research and practice during the 20th century. Secondly, it presents the current concept of nutrient management with application to grazed grassland. Finally, it discusses nitrogen (N) management of pastures and the tools to improve N management at operational level.Nutrient management under grazing has evolved from merely optimizing manure and fertilizer applications for high herbage yield towards improving nutrient use efficiency at farm level whilst maintaining productivity. Nutrient management under grazing is highly complex, because of the uneven distributions of nutrients in pastures, the difference in nutrient element requirements for herbage growth and dairy production, and the difference in mobility between nutrients and the tendency of especially N to escape from the system. Furthermore, boundary conditions of nutrient management in practice change frequently due to changes in manure policy.The economic costs of nutrients in dairy farms have decreased during the 20th century, but the time and costs associated with nutrient management in practice have increased, mainly because of the manure policy. Nutrient balance sheets have greatly contributed to increased understanding of nutrient cycling and nutrient management in dairy farming, as they provide guidance to improving nutrient use efficiency. Emphasis in nutrient management under grazing has been on N and to a much lesser extent on P, K and Mg. The emphasis on N follows from its impact on productivity and the environment. In the near future, there will be increasing attention also for P and micro-nutrients like copper and zinc as they tend to accumulate in intensively managed grassland soils to levels critical for the environment and animal and human health.
