Shredding Crop Stubble Undercuts Soil Protection Benefits Long-Term

Agronomy experts explain why standing crop residue protects soil and reduces costs for crop growers, while shredding often yields little benefit at higher costs.

NASHVILLE, TENN. (RFD NEWS) — Leaving crop residue standing after harvest or a failed crop can deliver meaningful soil and economic benefits, while shredding or plowing stubble often works against both goals. That’s the message from Dr. Calvin Trostle, Texas A&M AgriLife Extension agronomist, who says many producers still underestimate the value of existing residue.

Trostle notes that standing stubble serves as a free “dead cover crop,” protecting soil from wind erosion, improving water capture, and reducing surface crusting without requiring additional moisture or inputs. Shredding residue, by contrast, loosens leaves that are more likely to blow away and typically costs about $10 per acre with no measurable return.

Research and field experience indicate that incorporating residue through tillage has little effect on long-term soil organic matter. Instead, leaving root systems intact under minimal tillage yields the greatest gains in soil health. Even low-biomass crops such as cotton and sunflower can provide erosion protection when left standing.

Trostle encourages producers to focus on planting into residue using adjusted equipment rather than removing valuable ground cover.

Farm-Level Takeaway: Standing crop residue protects soil and saves money — shredding often yields little benefit at a higher cost.
