Answer:
The list of soil and water resource problems on the agricultural agenda has increased enormously over the past 15 years. Long-standing concerns about soil erosion and sedimentation have been supplemented with renewed concerns about soil compaction, salinization, acidification, and loss of soil organic matter. The loss of nitrates, phosphorus, pesticides, and salts from farming systems to surface water and groundwater has, in some ways, supplanted traditional concerns about soil degradation.
Efforts to address this larger complex of resource problems have been hampered by concerns about trade-offs. Management practices that have been designed to reduce soil erosion are now scrutinized for their role in increasing leaching of nitrates or pesticides to groundwater. Practices designed to reduce the amounts of sediment-borne pollutants delivered to waterways are sometimes thought to increase the amounts of the soluble forms of those pollutants delivered in runoff water. Such findings have raised doubts about society's ability to manage what appears to be unavoidable environmental trade-offs. Efforts to improve agriculture's environmental performance must be weighed against efforts to reduce costs of production, increase production, and maintain U.S. agriculture's share of world markets.
Uncertainty about trade-offs makes policy development difficult because it is hard to determine the best approaches for improving the effects of farming systems on soil and water resources. This difficulty is further complicated by the inherent regional and local variabilities in farm enterprises and soil and water resources. Soil and water quality
