A new USDA study shows that farmers using combinations of erosion-control and nutrient-management practices on cultivated cropland are reducing losses of sediment, nitrogen and phosphorous from farm fields and decreasing the movement of these materials to the Great Lakes and their associated waterways.

If a harvested field catches fire, no-till farmers should assume at least some of the field nutrients went up in smoke, according to two studies.

Two recent studies by Iowa State University researchers show that phosphorus runoff into Iowa's rivers, streams and lakes can be slowed by farmers changing how they plant and fertilize their crops.
