This project plans to expand current work exploring dry farming techniques as a climate adaptation strategy to deal with more drought conditions in western Oregon and Washington when less water is available for irrigation or water users get cut off from water rights. The researchers will use organic production methods to further investigate the role of soil health management for improving soil moisture holding capacity through the application of different treatments. The ultimate goal is to better understand how dry farming in western Oregon and Washington can be used as a drought resilient strategy.
This project will investigate the use of five treatments:
- ‘Dust mulch’ tillage to 4-6 inch depth to stop capillary movement of water from soil and prevent soil evaporation (most common commercial practice - not actually dust, but small soil clumps)
- Deep mulch (leaf or straw)
- Organic high residue cover crop no-till system using rolled cover crop (common vetch or crimson clover)
- Regular tillage treatment (2-3 inch depth)
- Weedy treatment (control).
