AgroforestryAgroforestry in the Century of Cities and Climate Change: Blurring the Lines Between Fields, Forests, and Backyards

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

Agroforestry is an intensive farming system that intentionally combines trees and shrubs with crops and/or livestock on the land to optimize biological interactions to maximize farm output and environmental services. John Munsell, Catherine Bukowski, John Fike, and Katie Trozzo of the Virginia Polytechnic Institute and State University will provide a comprehensive primer on agroforestry and practical applications in urban, suburban, and rural areas and the techniques underpinning highly productive operations. This session is ideal for beginning forest farmers, early career farmers, or experienced farmers looking to enhance their management with agroforestry principles. Topics include: agroforestry principles and concepts; silvopasture and alley cropping; multi-functional riparian buffers and forest farming; windbreaks, multi-story cropping, and community food forests. The session will include a mixture of slide shows, discussion, and planning and design exercises using virtual reality and pen and paper.

Reginaldo Haslett-MarroquinPoultry-Centered Regenerative Agriculture Systems

8:30 a.m. -5:30 p.m.

Join author Reginaldo Haslett-Marroquin and Tony Wells of the Main Street Project for a full-day workshop, which will cover regenerative poultry production and system-level design, farm-level production, and local, regional, and national implementation strategies. It will also help you align farm enterprise and system-level enterprise management based on five core areas. Reginaldo and Tony will describe the process for organizing and deploying fully integrated regional farm clusters designed to solve some of the most critical aspects of launching a regenerative poultry industry such as feed, poultry processing, steps to achieving scale, manure management, grain growing, and game-changing innovations that are revolutionizing the labor and cost of producing top quality poultry at a larger scale.

Get an A-to-Z exploration of this innovative system design, learn about enterprise stacking and integration and its value as a foundation for building a regenerative poultry industry sector, and discover how you can integrate more than 14 enterprise sectors capable of generating large-scale results.

Ben HartmanUsing the Lean System to Increase Profits with Less Work for Market Growers

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

"Lean" is a Japanese work method designed to increase the flow of value in a workplace with less labor. Toyota, in particular, is looked to as a model of this lean approach. In this workshop, Ben Hartman, author of The Lean Farm and The Lean Farm Guide to Growing Vegetables, and co-owner of Clay Bottom Farm in Indiana, will explain how he and his wife, Rachel, use concepts borrowed from lean to earn a comfortable living working about 35 hours per week each on less than an acre of land.

The workshop will cover management strategies like heijunka (load-leveling), 5S organizing, and kaizen (continuous improvement), as well as production techniques like single-piece flow. He will also cover Clay Bottom Farm's specific techniques for growing a range of vegetables with lean thinking. He will explain how they use lean to reach their sales goals while ensuring they have time to spend with family and friends and on hobbies they enjoy.
