Project Background
UC Davis and Fresno State will partner with growers to evaluate deep root irrigation (DRI), pressure compensated subsurface drip irrigation (PSDI), and Hybrid Pb cover crops. Directly watering the root zone via DRI and PSDI may provide opportunities to save water and address key barriers to cover crop adoption. Hybrid Pb is a new cool-season cover crop which differs from traditional cover crops in that it is perennial and dormant in the summer. On-farm trials will assess and extend biogeochemical, economic, and ecological benefits and tradeoffs for these practices as well as soil health outcomes.
