Evapotranspiration of pistachios in saline conditions with Daniele Zaccaria
Pistachios are very salt tolerant, at least compared to most of the other orchard crops that are grown in California. However, this does not make them immune to the effects of salinity. Daniele Zaccaria recently wrapped up a four year study examining the water use of trees under varying levels of soil salinity and found that water use decreases as soil salinity increases. This has major implications for tree health and water use post SGMA. Listen to find out more.

Whole orchard recycling: application, fertilization, and diseases with Brent Holtz
Whole orchard recycling is thepractice of incorporating recycled wood chips from oldorchards into soil priorto planting a new orchard. While this can change or improve howthe new orchard grows and the soil properties for the site, there are still various thingsgrowers need to consider if adopting this practice. Cameron Zuber (Merced and Maderacounties) has compiled some insights on managing application and incorporation ofwood chips,fertilization, diseaseswith regards to whole orchard recycling from Dr.Brent Holtz (San Joaquin County) recorded during a field day in Merced County.

Navel Orangeworm mating disruption neighbors program
Mating disruption has been found to reduce NOW damage in almonds by, on average, 50%, however we think it is most effective when it is applied in blocks that are 40 acres or larger. This means that a lot of growers who may be interested in mating disruption feel like they may not be able to use it due to their small blocks. A collaborative partnership between the Almond Board of California, University of California Agriculture and Natural Resources, Land IQ, and Blue Diamond Growers have put together the Neighbors Program, where interested growers can register their blocks and will be connected with neighbors who are also interested in implementing mating disruption. Interested in registering your blocks? Click here, and listen to the episode to get the passcode!

Whole orchard recycling in walnuts with Luke Milliron
Whole orchard recycling (WOR) is becoming commonplace in almonds, and we have several research trials scattered across the state examining best practices and potential benefits from this practice. It has not been looked at as extensively in walnuts, which will contribute much more biomass to the soil. Luke shares the results from some of this trials in this episode.
