“A bare plowed field is hungry, thirsty and running a fever.” That statement sure caught my attention when I read the handout called “Soil Health/Soil Quality” by Peter Hartman, NRCS Soil Scientist – Rochester, Minnesota. A few other things to consider:
- There are 9 billion living organisms in just a tablespoon of soil.
- Keep soil covered with living plants or plant residues to avoid erosion.
- Minimize disturbance of the soil to limit weed seeds.
- Maximize diversity of plants in rotation, using plants from many different groupings such as flowers, herbs, vegetables, ground covers for visual interest and to limit disease that can spread in monocultures.
- Keep living roots in the soil to hold the soil in place as much as possible. Consider cover crops off-season.
“Tillage is bad for the soil, tillage plants weed seeds” notes Hartman. Community gardeners, lets keep the soil food web working! Ruth’s Stouts book: Gardening Without Work: for the Aging, the Busy, and the Indolent is a great reference for no till gardening and can be found at the Red Wing Public Library. If you would like to see these methods in action, stop by the demonstration plots at Spring Creek Community Garden or email me at firstname.lastname@example.org .
