Research Abstract |
One of major Policies proposed in 1990 Farm Bill is Conservation and Environment. The Policy constitutes seven items ; 1. Amendments to the Conservation Reserve Program 2. Ground and Surface Water Quality, 3. Protection of Wetlands, 4. Sustainable Agriculture, 5. Conservation Compliance, 6. Multi-Year Set-Aside, 7. Great Plains Conservation Program The United states is fortunate to have an abundant, but finite, resource base of fertile soil, water, and land. The environment has a limited capacity to absorb production by-products, such as soil erosion and animal waste, and excess input application, such as fertilizers and pesticides, without reducing productivity or increasing environmental and human health concerns. Issues on resource and envirornment caused by crop farming are (1) soil erosion, (2) water pollution, (3) exhaustion of ground water, (4) salinization of farm land and (5) damages to the ecology. These issues are related to each other. For example, a number of residual by-products generated by crop farming, which can be carried into waterways by runoff or can potentially leach into ground water supplies, may degrade water quality or may do damages to the ecology. Such residuals are nutrients from chemical fertilizers and animal -anure, pesticides, sediment, and dissolved minerals and salts.
