In a cover article for Ode Magazine, Larry Gallagher describes the planet's soil problem — poor land-use practices destroy soil faster than nature can create it — and examines how farmers and others are trying to solve the problem. He starts with a visit to Ecology Action in California's Mendocino County, a non-profit focused on sustainable agriculture that is headed by John Jeavons. Jeavons claims that his biointensive system can grow food while also increasing topsoil depth at a rate that is 60 times faster than nature. Gallagher's next stop is Jepson Prairie Organics in Vacaville, where green waste from San Francisco goes through a 60 day composting process, then is shipped to nearby vineyards, farms, and other growers (related: Marc's write-up of his tour of the Jepson facility). One of the users is Nigel Walker of Eatwell Farm. Walker works hard to maintain good soil on his 105-acre organic farm by planting cover crops, avoiding the use of heavy equipment, rotating chickens through the fields, and spreading compost from Jepson. Walker notes that there's still a gap in the soil loop, the digested remains of the food that he sells, and jokes that “I should make you show up with a bucket of waste each week you pick up your [CSA] box.” Gallagher then explains one of his own contributions to soil recovery: the composting toilet in his backyard. Finally, he looks at "green burial" practices, a way to return the nutrients in your body to the Earth with the least negative impact. (Ode Magazine)
