Irrigation systems must be well designed, maintained, and operated correctly so water is applied uniformly to a crop. Also, irrigation schedules need to match the water demand of the crop. This talk described tools and approaches to help increase water use efficiency. Click the link below for resources from this seminar.

This seminar covered some basics of organic nitrogen management and how plant-available nitrogen is released from various organic fertilizers and composts through a biological process called mineralization. Click the link below for resources from this seminar.

This workshop included the following topics: nutrient management, irrigation management, cover crops, managing trees during dormancy, insect pest management, disease management, and weed management. Click the link below for resources from this workshop.

This seminar shared research information about when and to what extent the benefits of Mycorrhizal fungi are seen in California vegetable systems. Topics discussed included multiple ways different management practices could support (or not!) mycorrhizal fungi, from inoculation to soil health practices like cover cropping and reduced tillage.

This seminar describes the steps taken to discover, import, screen and develop petitions to release a novel bio-control agent into the US to help suppress the spotted wing drosophila. It also describes the potential levels of parasitism expected, and the administrative process to get material approved for field release.

This webinar covered organic soil fertility management strategies for small-scale organic vegetable farmers. Topics included management of major and minor plant nutrients including nitrogen, phosphorus, and potassium, and crop fertility inputs. The talk also covered fertility management based on soil test results and accounting for nitrogen in irrigation water. Click the link below for resources from this seminar.

This webinar focused on weed management strategies for small-scale and organic vegetable farmers. Topics included seedbank management, using tarps and flame weeding, physical weed control options, hand tools, cultivation tool stacking, and optimization of tools.
