2. Reduce herbicide input over time

3. Protect herbicide chemistry

4. Less labor (compared to tillage)

5. Mitigate wind and water erosion

6. Moisture conservation

7. Likely higher yields on dryland

8. Possibly reduce irrigation

9. Reduces Thrips damage

10. Likely reduce impact from ryegrass and horseweed.
