As we near the finish of the 2001 planting season, it is time to take a break and measure remaining crop residue--the stems and stalks remaining from last year's crop. Knowing how to measure existing residue as crops emerge helps to determine how well soil is protected from erosion. For most Iowa soils, high residue levels translate directly into soil conservation benefits. The consensus among experts is that the most effective conservation tillage practices leave at least 30 percent crop residue after planting.
