AgroforestryMarket Gardening 2.0

10:00 a.m. -4:30 p.m.

In this full-day training, renowned author and market gardener Jean-Martin Fortier will demonstrate the important components of his success, including both physical techniques and management practices that enliven his agro-ecological approach to productive, profitable market gardening. He will use a combination of slides, lecture, and interactive dialogue to help you understand his system and how you can apply its lessons to your own operation. This new and updated presentation will focus on crop planning and management, new physical tools and computer-based organizational tools, and the often-overlooked importance of standard operating procedures.

Jody PadghamLearning from the Numbers: Deepening Farm Financial Awareness

10:00 a.m. -4:30 p.m.

You've concentrated on building a farm business that fits you, developed basic skills in financial recordkeeping, and can produce out a few simple reports. Now it's time to understand how the numbers associated with your business can be used to improve management decisions. Are products priced correctly? Are various enterprises making or losing money? Have you chosen markets that will generate the most profit? Will cash be available to pay for expenses when you need it? Do you have the information you need to make sound equipment or other capital purchases? How profitable is your farm operation over time?

Jody Padgham, co-author of Fearless Farm Finances, supported by Becky Rondy, co-owner of Green Edge Organic Gardens, will introduce numerous ways in which your financial records can be refined and used to explore these and other issues. Leave this workshop with a copy of Fearless Farm Finances, worksheets, and other tools to help manage your operation profitably.

Practical Hemp FarmingWhat the Hemp is Going On?! A Practical Guide to Hemp Farming in Ohio

10:00 a.m. -5:00 p.m.

Legalized hemp gives farmers a new option for diversifying their crop rotations, as well as their businesses, but many questions remain about how to grow and sell it profitably and legally. This day-long session will look at the various market opportunities, like CBD oil, fiber, grain, and certified seed crops, and their corresponding production considerations. A team of experts from the Ohio Department of Agriculture hemp program, the Ohio Seed Improvement Association, and Central State University Extention will discuss seed, transplant, and clone availability; fertilization and weed control; planting and harvesting; short- and long-term market opportunities and important financial considerations; regulation and compliance. Learn about common pitfalls so that you can take advantage of this opportunity with your eyes wide open.
