Book Description
In the 1970’s, agriculture in the United States seemed to be booming. With an extra demand for crops, extra acres were taken on to increase production which was predicted to increase further with an ever-growing population. However, concerns were beginning to be raised over the adequacy of land for crops as potential croplands began to be converted into urban areas as well as the effects of soil erosion decreasing the quality of these croplands. Originally published in 1983, this study investigates the threats to crop productivity in the U.S. with a focus on human-made problems. This title will be of interest to students of environmental studies.

Book Description
Annually, over a billion tons of soil erodes from the nation's cropland, and thousands of other acres, including wetlands, are converted to new cropland. Soil erosion reduces the land's productivity and impairs water quality; drained wetlands reduce flood control. Under the 1985 Food Security Act, farmers risk losing federal farm payments if they do not apply conservation practices to reduce erosion or if they drain wetlands. Concerns about soil erosion and wetlands conversions continue, however, as do concerns about the U.S. Department of Agriculture's (USDA) Natural Resources Conservation Service's implementation of these provisions. GAO reviewed field offices' and headquarters' implementation and enforcement of the 1985 act's conservation compliance provisions. USDA's Natural Resources Conservation Service has not consistently implemented the 1985 Food Security Act's conservation provisions. Inconsistent implementation increases the possibility that some farmers receive federal farm payments although their soil erodes at higher rates than allowed or they convert wetlands to cropland. According to GAO's nationwide survey, almost half of the Conservation Service's field offices do not implement the conservation provisions as required because they lack staff, management does not emphasize these provisions, or they are uncomfortable with their enforcement role. For example, field offices do not always find a farmer in violation for failing to implement an important practice, such as crop rotation, and do not always see whether a farmer has corrected the problem; they also do not always check for wetlands violations. The Conservation Service's weak oversight of its field offices further impairs implementation of the provisions. In the process of selecting samples of cropland tracts to assess farmers' compliance, the Conservation Service disproportionately emphasizes tracts with little potential for noncompliance, such as permanent rangelands. This selection process leads to inflated compliance rates. The Conservation Service also has no automated system to promptly inform its field offices of the tracts selected for compliance reviews or to enable the offices to efficiently report their review results. Therefore, the field offices cannot conduct timely reviews--during critical erosion periods--and provide headquarters with up-to-date information. Finally, the Farm Service Agency, the USDA agency responsible for withholding benefits for violations identified by the Conservation Service, often waives these noncompliance determinations without adequate justification. Without support from the Farm Service Agency, the Conservation Service's field staff have less incentive to issue violations.

Book Description
This report assesses the potential of U.S. cropland to sequester carbon, concluding that properly applied soil restorative processes and best management practices can help mitigate the greenhouse effect by decreasing the emissions of greenhouse gases from U.S. agricultural activities and by making U.S. cropland a major sink for carbon sequestration. Topics include: Describe the greenhouse processes and global tends in emissions as well as the three principal components of anthropogenic global warming potential Present data on U.S. emissions and agriculture's related role Examines the soil organic carbon (SOC) pool in soils of the U.S. and its loss due to cultivation Provides a reference for the magnitude of carbon sequestration potential Analyzes the primary processes governing greenhouse gas emission from the pedosphere Establishes a link between SOC content and soil quality Outlines strategies for mitigating emissions from U.S. cropland Discusses soil erosion management Assesses the potential of using cropland to create biomass for direct fuel to produce power Details the potential for sequestering carbon by intensifying prime agricultural land The Potential of U.S. Cropland to Sequester Carbon and Mitigate the Greenhouse Effect provides an exceptional framework for the adoption of science-based management methods on U.S. cropland, encouraging appropriate agricultural practices for the sustainable use of our natural resources and the improvement of our nation's environment.
