    Why woodchip size may matter with whole orchard recycling

    Why woodchip size may matter with whole orchard recycling

    Incorporating large amounts of woody biomass into soil, such as in whole orchard recycling (WOR), can promote carbon sequestration, nutrient recycling, and ecosystem health in agricultural fields. Yet uncertainty regarding the effects of WOR on soil carbon and nitrogen dynamics influences management decisions. Recently, Mae Culumber, Ph.D. with UC Cooperative Extension, Suduan Gao, Ph.D. with the USDA Agricultural Research Service, and others performed research to evaluate the effects of woodchip size and interaction with nitrogen fertilization on carbon dioxide and nitrous oxide emissions as well as soil organic carbon change. On this episode of Growing the Valley, they sit down with guest host Cameron Zuber to discuss some of their findings and how this may provide some considerations when implementing WOR.

    Sarah Light on Soil Health

    Sarah Light on Soil Health

    Soil health is broad term that encompasses a important topic: functional soil that can support human activities, animals, and plants. Measuring soil health can be difficult even for soil scientists, but in today’s episode, Sarah Light shares some tools that growers, PCAs, and CCAs can use to judge soil health in their or their clients’ orchards.

    Florent Trouillas on the 2023 aerial phytophthora outbreak in almonds

    Florent Trouillas on the 2023 aerial phytophthora outbreak in almonds

    In 2023 UCANR advisors and specialists got an unusual number of farm calls on branch cankers in almonds, many of which turned out to be aerial phytophthora. Florent Trouillas with UC Davis goes over the pathogen, its lifecycle, and the conditions in 2023 that led to this outbreak.

    Amisha Poret-Peterson on soil microbiome basics

    Amisha Poret-Peterson on soil microbiome basics

    This week, we share an episode that was TWO YEARS IN THE MAKING (if you count continually rescheduling episode recording sessions due to various conflicts and then forgetting about it for a year as making an episode). Phoebe interviews Amisha Poret-Peterson with the USDA-ARS on the basics of soil microbiology. We discuss the complexity and role of the soil microbiome, bulk soil vs the rhizosphere, and more! Listen to hear some very amazing things.

    Lu Zhang on Dust During Pistachio Bloom

    Lu Zhang on Dust During Pistachio Bloom

    Lu Zhang provides an update on work published last year on the effect of dust on pistachio pollen, flowers, nut set, and blanking (it’s not good!). Please note that there are other physiological causes of blanking, such as incomplete pollination or aborted kernel development, and that we have not determined how much dust could contribute to blanking in the field. Also, the episode was recorded before the heavy rains in March in the southern San Joaquin Valley, so high dust conditions may not occur this year.

    The American Society for Horticultural Science dropped its paywall, so you can read the article yourself at https://journals.ashs.org/hortsci/view/journals/hortsci/54/11/article-p1967.xml.

Merry Christmas

Thank you guys for hosting!

Request from a big fan

I love this podcast! The hosts bring a deep expertise on the topic at hand but in a very user friendly way. I have a request. I have a family-run farm where we harvest ginkgo nuts. There is very little available info out there on ginkgo trees. I would LOVE to hear a special episode on this up-and-coming component of the California agricultural scene!

Very interesting and well produced.

Even though I only took bio a long time ago this podcast is easy to understand and very educational. I appreciate learning about California crops. Also Luke has such a nice and relaxing voice; definitely rivals the voices of those on NPR.
