Phenology - Bringing to Light Recurring Events

Authors: Ben Faber


Plants, therefore avocados, go through different growth stages, so called phenological stages. Regular periods where they grow and differentiate from seed to various vegetative stages, flowering and finally seed production. Avocados have a preset pattern of phenology that occurs depending on variety and where it is grown, driven by light, temperature, water availability and often by different stresses, such as cold, heat, and heavy or light crop load.

Tips For Planting Avocado Trees: Move Fast & Break Things

Author: Ben Faber


And live to regret it when it comes to planting a tree. Bring out that power auger and dig a hole and slam that tree in the ground and move on to the next planting hole. If it's rocky soil, with good drainage, the trees may look like this two years later. Alive, but some are much bigger than others. In a loamy, heavier soil with more normal drainage, they would most likely be DEAD.

Citrus Bud Mite

Author: Ben Faber


Most commonly we associate the malformed fruit we see in lemons to citrus bud mite. But it can also occur on other varieties of citrus in Southern California, including in this case to tangelos. If there's enough fruit to bite into, it's still edible. Citrus bud mite is very small, elongated and somewhat tapered at the posterior end, and has four legs at the front end near the mouth. Read more here...

Did California’s Ag Overtime Law Help Farmworkers?

Author: Ria DeBiase


Proponents of California's agricultural overtime law, AB 1066, have called it a victory for farmworkers, while critics have asserted that it will harm the very people it was designed to protect. New research by Alexandra Hill, UC Cooperative Extension specialist and assistant professor in UC Berkeley's Department of Agricultural and Resource Economics, shows that, on average, there has been a decrease in worker hours and wages. Her estimates suggest that in the first two years of its implementation, California's farmworkers worked a total of 15,000 to 45,000 fewer hours and earned a total of $6 million to $9 million less on their weekly paychecks than they would have without this law in place.

Eye on the Environment: Landmark decision changes the future of composting in Ventura County

Author: David Goldstein


Two weeks ago, Agromin, the organics recycling arm of Harrison Industries, won the maximum possible $10 million award in a competitive grant process offered through the California Department of Resources Recycling and Recovery, CalRecycle. The funds will energize a major leap forward for recycling in Ventura County, partially funding development of a commercial-scale composting operation on the Limoneira Farm near Santa Paula. The project at Limoneira received a Conditional Use Permit from the Ventura County Board of Supervisors in February 2022, but the approved plan for the site, and conditions of the permit, include massive new infrastructure, requiring time and money to build.
