Water Management During Drought Conditions

Michael Cahn, Irrigation and Water Resource Farm Advisor at UCCE Monterey County

January 25, 2022

 

Irrigation(small)

During drought conditions when water supplies are limited, understanding the water needs of the crops you would like to grow, your available irrigation supply, and best practices for efficient irrigation water application are critical. This seminar will focus on how to manage your irrigation practices during a drought.

February 8, 2022

 

unnamed (2)

This webinar focused on organic soil fertility management strategies for small-scale organic vegetable farmers. Topics will include management of major and minor plant nutrients including nitrogen, phosphorus, and potassium, and crop fertility inputs. The talk will also cover fertility management based on soil test results and accounting for nitrogen in irrigation water.

So Many Products, So Little Time, So Much Confusion –Building Capacityfor Bigger Potential of Crop Biostimulants among Organic Small Farms

Zheng Wang Vegetable Crops and IrrigationAdvisorwith University of California Cooperative Extensionin StanislausCounty

February 2, 2022

 

This seminar will begin with an overview ofthe purpose of using crop biostimulants. Zheng will go over effective practices for selecting biostimulants to match the needs of your systemand successful ways to deliver biostimulants, using examples of microbial-based and other types of products. Finally, he will cover some basics for effectively measuring the value of bio stimulants for your farm production.

Managing Mycorrhizal Fungi in Your Soil

Tim Bowles, UC Berkeley, assistant professor of agroecology at UC Berkeley.

Mycorrhizal fungi are often viewed as star players in sustainable agriculture, and for good reason. When they form intimate associations with crop roots, they can help increase nutrient uptake, help crops deal with water stress and possibly reduce soil borne disease pressure. In this workshop, UC researchers will share research and experiences about when and to what extent these benefits are seen in California vegetable systems. Come learn — and share your own experiences — about the multiple ways management could support (or not!) mycorrhizal fungi, from inoculation to soil health practices like cover cropping and reducing tillage.

Bagrada
January 12, 2021
 
Bagrada Bug Community Forum:
Bagrada Bug is an imerging invasive stink bug pest in California, which preferentially feeds on plants in the mustard family (i.e. broccoli, kale, cauliflower, cabbage). It is a sucking insect and can cause severe yield losses, especially when it attacks young plants. On January 12, 2021 UCCE hosted a forum for Yolo, Sacramento, and Solano county organic growers to discuss their experiences with fighting bagrada bug. Paul Undehill and Andrew Brait led the discussion.
