The distance of local
About twenty years ago the University of Missouri Southwest Center experimented with a 'close planting' garden. On a 30' x 30' plot one ton of vegetables was grown using only 27.5 hours of labor. Today it takes 4 hours, per person, of a five day work week to pay for purchased food. An estimated 70% of processed foods on the grocery store shelves contain genetically engineered ingredients, and then there's the distance that most food travels before getting to your store. Whole Foods Market defines local as within 700 miles. For Kroger stores, it's a two state range. Giant Eagle defines local as from the same state the store is located. This graphic from 1919 compares 'Vegetables Grown For Home Use Only' and 'Vegetables Grown For Sale'. So, what is he distance of Local?
You can't get more local than your own backyard. This is the time of year to start planning for next year's garden. Cover crops of green manure ( buckwheat, annual rye grass, clover, etc.) should be planted now. They'll add nutrients, aerate the soil, fix nitrogen, and feed the microbial life of the soil. Adding chopped leaves, from deep rooted trees, will mineralize the soil. Bare ground is the enemy of garden productivity.
Thank you to the staff of Farming Magazine for allowing me to use this graphic. It appeared in the Fall, 2013 edition of their great publication.
