The U.S. Environmental Protection Agency requires concentrated animal feeding operations to develop and implement a comprehensive nutrient management plan. Changes in manure management to meet nutrient application standards will generally increase production costs. Some of these costs can be offset by savings from replacing commercial fertilizer with manure nutrients, and through financial assistance programs such as the U.S. Department of Agriculture's Environmental Quality Incentives Program (EQIP). A manure application cost model was used to examine the costs to confined dairy farms of meeting nutrient application standards, and the ability of fertilizer offsets and EQIP to reduce these costs. |

Nitrogen is the single most important input a farmer can control to increase crop yields on nonirrigated fields. Given this, and the fact that nitrogen has been a relatively inexpensive input, farmers have an economic incentive to “apply a little extra” to ensure that crops have the necessary nutrients when they need them most. As a consequence, excess nitrogen remains in the soil and freely moves into water resources or into the atmosphere. Agriculture is the single largest source of nitrogen compounds entering the environment in the U.S., contributing 73 percent of nitrous oxide emissions, 84 percent of ammonia emissions, and 54 percent of nitrate emissions in recent years. The production and release of nitrogen, however, has greatly changed the Earth’s... |

U.S. farmers and ranchers produce a wide variety of commodities for food, fuel, and fiber in response to market signals. Farms also contain significant amounts of natural resources that can provide a host of environmental services, including cleaner air and water, flood control, and improved wildlife habitat. Environmental services are often valued by society, but because they are a public good—that is, people can obtain them without paying for them—farmers and ranchers may not benefit financially from producing them. As a result, farmers and ranchers under-provide these services. This report explores the use of market mechanisms, such as emissions trading and eco-labels, to increase private investment in environmental stewardship. Such investments could... |

In recent years, structural changes in the hog sector, including increasing farm size and regional shifts in production, have altered manure management practices. Over the same period, changes to the Clean Water Act, new state regulations, and increasing local conflicts over odor have influenced manure management decisions. This study uses data from two national surveys of hog farmers to examine how hog manure management practices vary with the scale of production and how these practices evolved between 1998 and 2004. The findings provide insights into the effects of structural changes and recent policies on manure management technologies and practices, the use of nutrient management plans, and manure application rates. |

The Environmental Protection Agency and the U.S. Department of Agriculture are promoting point/nonpoint trading as a way of reducing the costs of meeting water quality goals while giving nonpoint sources a larger role in meeting those goals. Farms can create offsets or credits in a point/nonpoint trading program by implementing management practices such as conservation tillage, nutrient management, and buffer strips. To be eligible to sell credits, farmers must first comply with baseline requirements. The EPA defines a baseline as the pollutant control requirements that apply to a seller in the absence of trading. EPA guidance recommends that the baseline for nonpoint sources be management practices that are consistent with the water quality goal. A... |

Nitrogen is an important agricultural input that is critical for crop production. However, the introduction of large amounts of nitrogen into the environment has a number of undesirable impacts on water, terrestrial, and atmospheric resources. This report explores the use of nitrogen in U.S. agriculture and assesses changes in nutrient management by farmers that may improve nitrogen use effi ciency. It also reviews a number of policy approaches for improving nitrogen management and identifi es issues affecting their potential performance. Findings reveal that about two-thirds of U.S. cropland is not meeting three criteria for good nitrogen management. Several policy approaches, including fi nancial incentives, nitrogen management as a condition of farm... |
