Organic growers may be interested in the following new eOrganic – eXtension webinars that focus on various organic crop and livestock topics:
16 Dec 2015: Nitrogen management in organic strawberries: challenges and approaches
Nitrogen management is one of many challenges that organic strawberry growers face. In this webinar, we will address the challenges of nitrogen management in strawberries, pattern of nitrogen uptake over plant growth cycle and synchronizing N supply, pre-plant amendments and leaching losses, and issues with fertigation efficiency.
Presented by Carol Shennan and Joji Muramoto of the University of California, Santa Cruz and Mark Gaskell of the University of California Cooperative Extension. The webinar takes place December 16, 2015 at 2PM Eastern Time. The webinar is free and advance registration is required.
2 March 2016: Design and management of organic strawberry/vegetable rotations
Findings from a four-year rotation study and on-farm trials will be discussed. The study compared two and four year rotations with either broccoli or lettuce as the primary vegetables grown between strawberry crops. Disease and fertility were managed by a combination of winter cover crops and use of either anaerobic soil disinfestation or mustard seed meal additions prior to planting strawberry. Data on yields, disease incidence, soil nitrogen dynamics
and preliminary economic analysis will be presented.
Presented by Carol Shennan and Joji Muramoto of the University of California, Santa Cruz. The webinar takes place on March 2, 2016 at 2PM Eastern Time. The webinar is free and advance registration is required.
11 Feb 2016: Grazing Systems and Forage Quality of Grasses for Organic Dairy Production
Pasture management and forage species selection within a farm can influence the feed quality of pasture forage for grazing dairy animals. In this webinar, Brad Heins will describe a multi-year grazing project, funded by the USDA Organic Research and Extension Initiative aimed at enhancing in-field and landscape level species diversity of grasses across the grazing season. He will discuss forage quality of cool-season and warm-season grasses (Teff and BMR Sorghum-Sudangrass) and present performance of dairy cows grazing in these pasture systems designed to maximize seasonal forage yield and quality and extend the grazing season.
The webinar will take place on February 11, 2016 at 2 p.m. Eastern Time. The webinar is free and advance registration is required.
24 Mar 2016: Unique Fly Control Methods for Organic Dairy Production
Along with the wonderful grazing season and hot summe
r weather, come flies! One issue, consistent among the livestock farmers, is how to control flies under organic conditions. In this webinar, Dr. Brad Heins will describe practical options for fly control on lactating cows and growing dairy animals. The discussion will include a comparison of the Bruce Fly Trap and Spalding Cow-Vac, two control options that were researched at the University of Minnesota through a project funded by the USDA Organic Research and Extension Initiative.
The webinar will take place on March 24, 2016 at 2 p.m. Eastern Time, 1:00 p.m. The webinar is free and advance registration is required.
