Free Webinar Will Help Specialty Crop Farmers Choose Cover Crops and Fertilizers


On Wednesday, April 17, at 6 p.m., the Ohio Ecological Food and Farm Association (OEFFA) will offer a free webinar designed for specialty crop farmers, titled "Estimating Cover Crop Nitrogen and Choosing Organic Fertilizers for Your Farm."

Nick Andrews, Oregon State University senior instructor and Small Farms Extension agent, will guide participants through the Organic Fertilizer and Cover Crop Calculator, a free online tool that predicts the nitrogen released by cover crops, organic fertilizers and compost, allowing farmers to easily compare the costs of different organic fertilizer programs. Andrews will explain the research behind the nitrogen mineralization models used in the calculator and demonstrate how this tool can be used to develop a cost-effective nutrient management program designed to address each farm's specific crop nutrient requirements.

Andrews specializes in horticultural crops with a focus on vegetables and organic production, and has conducted applied cover crop research. He provides general advice for small farms, organizes beginning farmer training programs and teaches composting workshops. He also edits the Oregon State University Small Farm website and regularly contributes articles to Oregon Small Farm News.

Setting Profitable Prices for Multiple Outlets" on Wednesday, April 24, at 7 p.m., and "Employees on Your Farm" on Wednesday, May 22, at 7 p.m. For more information or to register, click here.
