- Extreme viticulture: how Northeast growers farm vinifera organically and sustainably
- Barbara Shinn is fired up. In 1998 she and her husband, David Page, bought the parcel of land in Mattituck, Long Island, that would become the critically acclaimed Shinn Estate Vineyards, and immediately began preparing the soil for an experiment in high-intensity viticulture. "Our goal was to make an...

- Scaling from field to region for wind erosion prediction using the Wind Erosion Prediction System and geographical information systems.(APPLIED RESEARCH)(Report)
- Soil wind erosion and windblown dust have long been a major concern within the Columbia Plateau of the Pacific Northwest. Wind removes the fertile topsoil, thereby degrading soil quality and reducing agricultural sustainability. Sharratt et al. (2006), for example, estimated a loss of topsoil of 2,320...

- Mechanical thinning impacts on runoff, infiltration, and sediment yield following fuel reduction treatments in a southwestern dry mixed conifer forest.(Report)
- Increasing tree densities experienced since the early 1900s throughout forests in the western United States are associated with numerous ecological problems (Dieterich 1983; Covington and Moore 1994a; Covington and Moore 1994b; Kolb et al. 1994). These problems include, but are not limited to conversion from high-frequency,...

- No shortcutts in checking soil health
- Long-term experiments are a feature of many ARS research efforts. Whether in the Pacific Northwest, Midwest, or Southeastern regions of the United States, these kinds of studies provide valuable insights and, occasionally, unexpected results. A relatively new long-term experiment at Beltsville, Maryland, has shown that organic farming can build...

- The importance and challenge of modeling irrigation-induced erosion.
- Irrigation-induced erosion and rain-induced erosion result from very different systematics. Therefore, both cannot be predicted effectively using the same models. The average two-fold yield and three-fold economic advantage of irrigation over rain-fed agriculture, coupled with the fragility of irrigated land and the strategic importance of irrigation development to meet world...

- Unit source area data: can it make a difference in calibrating the hydrologic response for watershed-scale modeling?
- Watershed computer models such as the Soil and Water Assessment Tool SWAT contain parameters that describe watershed properties such as vegetative cover, soil characteristics, or landscape features. For investigations that involve changes in land cover or land management on agricultural lands, proper adjustment of these parameters is important not only...

- Potential impact of conservation tillage on conserving water resources in Georgia.
- Reduced tillage and surface residue increases infiltration, soil water content, and plant available water, while at the same time decreasing runoff and sedimentation. However, there is a general lack of knowledge and appreciation regarding the impact conservation tillage has on sustainable water resources. The objective of this study was to...

- Land use change and gully erosion in the Piedmont region of South Carolina.
- Land use change played an important role in the formation of gullies present today in the Piedmont of the Southeastern United States. Forested areas that were once cleared to cultivate cotton and consequently gullied are now, once again, covered with forest vegetation. Despite this forest cover, gullies are still considered...
