The Jeavons Center Mini-Farm Report
by John Jeavons, Executive Director, Ecology Action


As summer turns into autumn, our four new Farmer-Teacher Trainers (FTT) are becoming acquainted with The Jeavons Center mini-farm, and its steep terrain looking out over the Willits valley. They are building their skill with the GROW BIOINTENSIVE (GB) method, and are growing into a team. This garden has welcomed and educated, so many people over the last half-century! The atmosphere of nurturing and learning has been worked into the soil by the tending of countless learning hands and the gentle tread of farmer feet on the paths between the beds I helped dig into the harsh hillside so many years ago. This place is so generous in sharing—not only its abundant harvests of food, but of knowledge, and of a sense of harmony with the Earth.

As our new FTTs get a feel for the GB method, I reflect on what they will learn here. Of course, I hope this team will be part of this site for a long time, but I also know that life can take us in unexpected directions. My hope is that no matter what the future brings, the time that each person spends here at The Jeavons Center rewards them with skills and strengths that will be with them always, both in terms of practical skill, and in the garden of their mind and heart.

Mentored by TJC Assistant Mini-Farm Manager Suraya David Sadira, new garden staff learn to build fertility and achieve good yields by focusing on the following emphases—the nuts-and-bolts (or perhaps that should be nuts-and-seeds?)—of GB:

  • Good Soil Preparation: double digging and amending with site-grown compost creates good soil structure at least 24 inches deep. This is the foundational skill that allows us to transform the naturally unproductive soil at The Jeavons Center (rated “poor for grazing” meaning nutrient-limited, with poor structure, poor water retention, and pH issues) into a fertile, balanced soil rich in organic matter, capable of supporting abundant harvests year after year. • Sustainable Compost: one of the key differences between GB and other farming methods is the use of site-grown compost, rather than purchased amendments mined from other soils. The 60:30:10 ratio of carbon:calorie:income/mineral crops is carefully balanced to provide “closed-loop” sustainable fertility, with crops cycling back into soil as much as possible.

  • Living Mulch: in a forest, tree canopies create micro-climates on the ground below that are darker, cooler, and more humid than nearby unshaded habitats. The GB technique of close-offset spacing (rather than planting in rows) mimics this canopy effect by carefully spacing seedlings so that the mature plants will touch just enough to protect the soil in which they grow, but not so close that they experience stress from crowding. Years of practice helped us optimize spacing for hundreds of plants (which you can find in the Master Charts section of How to Grow More Vegetables). Close spacing reduces the need for other forms of mulch (which may not be sustainable) and contributes to GB’s extreme water efficiency, which allows us to grow food with as little as ¹/₃ - ¹/₅ the water of conventional farming, and also provides a tremendous reduction in the area needed to grow a complete vegan diet.

  • Diet Design: careful planning of crops in space and time also helps reduce the area needed to grow food. This means GB farmers use as little as half the soil (bed-crop-months) and half the water as other methods to grow the same amount of food. This is particularly important given world population levels: the smaller we can make our “foodprint” the better it is for the world’s soils and ecosystems.

  • Aikido Flow: “Aikido is not simply over-powering your opponent or competition of physical strength, one must begin to appreciate Aikido in terms of blending, the flow and out-pouring of energy, balance and timing and bring them all together in an integrated and effective way.” - Rev. Kensho Furuya. For a farmer, effective use of one’s body when working with the earth is essential for avoiding injury. Because GB uses manual labor instead of fossil-fuel-driven machinery, at TJC we incorporate a mental and physical flow which takes its flavor from the gentle martial art of Aikido as we work in the mini-farm. Learning not to fight the soil or your tools, and to be efficient and focused with your energy is key to sustainable long-term physical work. An excellent demonstration of this digging style can be found here.

  • Observations are everything! On paper, gardening can look like a simple series of repetitive tasks carried out on a schedule to achieve a set result. But the garden is not a machine, and does not exist in a vacuum. It is a living, changing community made up of billions of organisms – including the farmer! As my mentor Alan Chadwick said, "It is not the gardener that makes the garden. It is the garden that makes the gardener." He also said "A good gardener looks at every plant every day." This idea might seem preposterous if applied to conventional farming; how could you possibly pay attention to every plant in on 20 acres, much less on 2,000? But the beauty of small-scale farming is that Alan’s words make perfect sense, because if you are paying attention, you actually do know every plant. By building and tending each inch of soil by hand, all your senses become engaged, and you see your whole garden, every day, as familiar as the face of someone you love. With this level of engagement, you can see where adjustments need to be made to create harmonious balance and productivity. This is human-scale farming.

And so we move into autumn. As they learn to plant the sturdy carbon-and-calorie crops (fava beans, cereal rye, and barley) that will survive the cold, rain, wind, and snow of the next season, I hope that our new farmers experience the joy of this place, and that they will experience, as Alan Chadwick did, how: "And now, suddenly, this coming up of nature, of the garden, enters your diaphragm and connects again with the cosmic, and your spiritual image is lifted again into a real that no verbosity, no ordinary study through words, through books, can give you."

And I hope you all do, too.
