Standing residue is an effective means of controlling erosion and preventing dust emission in areas prone to wind erosion. In northern climates, standing stubble retains snow deposits and prevents loss of moisture from removal by wind, and in areas affected by water erosion, surface residue is an effective means of protecting the soil. The most effective and durable aerial portion of the plant for preventing erosion is the stem. Considerable difference in stem quantity, diameter, and projected area per unit mass exists among different crops and different varieties of a particular crop. We conducted a study to obtain relationships between mass of surface residue per ha as a function of crop yield, portion of stem and surface residue, and stem area per unit mass for cereal crops commonly grown on Pacific Northwest US dry-farmed cropland. Data for specific crops and implications for erosion control are presented.
