  • A GUIDE to SEASON EXTENSION for Illinois Specialty Crop Growers
    A GUIDE to SEASON EXTENSION for Illinois Specialty Crop Growers Terra Brockman, Cara Cummings, Jeff Hake Cover photo of Henry’s Farm, Congerville, IL by Terra Brockman Henry Brockman of Henry’s Farm got creative with season extension, using every bucket and basket he could find to create warmer microclimates around each tender transplant. Because if you’ve invested in great cultivars, and a hoophouse to start them in, and then transplanted them all to the fields in mid-May, you need to make sure they won’t all die when a late frost is predicted. And yes, they survived! ACKNOWLEDGEMENTS The Land Connection thanks the following people for their valuable contributions of time and expertise as we developed this guide: Lorien Carsey of Blue Moon Farm, Urbana, Illinois Alisa DeMarco of Prairie Fruits Farm & Creamery, Champaign, Illinois Marty Gray of Gray Farms, Watseka, Illinois Marnie Record of the Illinois Organic Growers Association Clay Yapp of Sola Gratia Farm, Champaign, Illinois We also thank Kira Santiago for her designing of this guide, and Tim Meyers for his excellent recording and editing of our three case-study videos.

Resources I live and farm at Twin Oaks Community, in central Virginia. We’re in zone 7, with an average last frost April 30 and average first frost October 14. Our goal is to feed our intentional community of 100 people with a wide variety of organic produce year round. Our Hoophouse at Twin Oaks • We have one 30’ x 96’ FarmTek ClearSpan gothic arch hoophouse. • We put it up in 2003, and like many growers we had the primary goal of growing more winter greens, early tomatoes and peppers. • We grow many different crops, rotating them as best we can. • Our hoophouse is divided lengthwise into five 4’ beds and a 2’ bed along each edge. • Our paths are a skinny 12” wide - maximum growing space. Winter Hoophouses Protection of 2 layers of plastic and an air gap: 8F (5C) warmer than outside on cold nights . Single layer hoophouses are not much warmer at night than outdoors. Plants tolerate colder temps than they do outside, even without adding any inner rowcover In our double layer hoophouse in zone 7, without inner rowcover, salad greens survive when it’s 14F (-10C) outside.

  • A Thriving Student Organic Farm at a Land Grant University
    Four-Season Student Farming John Biernbaum, Department of Horticulture, Michigan State University How do you tell the story? How much from the head and how much from the heart? Is it a narrative grounded in the academic literature, or is it rather a story about place, people, process and transformational change? The history of the Michigan State University Student Organic Farm (MSU- SOF) can be told in many ways. The account offered here is from the perspective of a tenured faculty member and professor who partnered with students, staff and other colleagues to cultivate what has developed into a thriving student organic farm at a land grant university. The intent is to paint an instructive picture for those seeking to start similar farms at other schools, as well as for those walking the path of personal growth in a "learning-farm" culture. The MSU-Student Organic Farm started as a location for organic high tunnel research and quickly expanded to a 48-week community supported agriculture (CSA) program to research and demonstrate year-round vegetable production and to provide students with organic farming experience. From the beginning, the goal of the MSU Student Organic Farm has been to incorporate student requests for practical organic farming opportunities with the additional need for research, outreach and service to the campus and local communities. Creating an integrated program has been a key objective, as well as a budgetary reality, for the SOF from the start. A research project established the site and funded the first two high tunnels, providing a foundation for later expansion.
