2024/25 WEBINAR SERIES AND FIELD DAY – ‘OPTIMIZE IRRIGATION
Events: Optimize irrigation to grow climate-resilient hazelnut trees
Hosts: Dr. Thorsten Knipfer (Plant-water relations laboratory, UBC-LFS), Zachary Fleming (Pacific Coast Agriculture), Karina Sakalauskas (BC Ministry of Agriculture)
Date: 2024/25 Winter/Spring
Locations: Webinars (online) / Field day (in-person, Van Maren Farms)
RSVP: November 8, 2024
Background: Climate change is causing unprecedent challenges for agricultural production and hazelnut irrigation requirements. Effective irrigation scheduling provides for water savings without affecting yield, control of vegetative growth that reduces pruning, and regulate disease pressure. Since soil moisture sensors provide no direct information on the water status of the tree, there is an urgent need to establish plant-based strategies to schedule irrigation and grow climate-resilient hazelnut trees.
Objective: This event series provides conceptual and applied knowledge that will help you to improve your irrigation scheduling and establish best management practices.
Benefits: By the end of this series, you have learned about concepts that inform irrigation management and acquired knowledge about decision-making tools to determine when and how much to irrigate.
Activities: The webinar and field day is targeted towards engagement of BC producers and knowledge transfer.
