  1. Healthy Soil an Antidote to Climate Change? (Audioboo.fm)
      Asks the question: "Is healthy soil the low-tech solution to climate change through regenerative agriculture?" 08-14

  1. How Farmers Are Protecting Against Drought (Cnn News)
      "During the Dust Bowl era, tilling soil (or loosening it) was a common practice on farms, making the heavily tilled, loose soil more susceptible to literally turning to dust and blowing away when it became too dry. Approximately 35.5 percent of U.S. cropland (88 million acres) is currently planted without tilling (according to 2009 USDA numbers)." 09-12

  2. No-Till Farming (Conservation Agriculture Systems Alliance)
      "Across North America voluntary producer organizations work hard to promote no-till systems and other practices that provide economic benefits as well as environmental benefits to their regions. These organizations share similar missions and goals, encounter similar challenges and struggle with all too common problems." 06-08

  3. No-Till Farming (Grist.org)
      "In essentially all cases where conservation tillage was found to sequester C[arbon], soils were only sampled to a depth of 30 cm or less, even though crop roots often extend much deeper. In the few studies where sampling extended deeper than 30 cm, conservation tillage has shown no consistent accrual of SOC [soil organic carbon], instead showing a difference in the distribution of SOC, with higher concentrations near the surface in conservation tillage and higher concentrations in deeper layers under conventional tillage ... Long-term, continuous gas exchange measurements have also been unable to detect C gain due to reduced tillage." 06-08

  4. No-Till Farming (ReducedTillage.ca)
      "The RTL Agronomy Library contains hundreds of articles from getting started in direct seeding to fine tuning no till systems. Topics include seeding equipment, residue management, weed control, crop rotations, soil quality and much more." 06-08

  5. No-Till Farming (Wikipedia.org)
      "No-till farming is considered a kind of conservation tillage system and is sometimes called zero tillage. It is a way of growing crops from year to year without disturbing the soil through tillage. Once called chemical farming, the terminology was changed[who?] in order to promote the idea of no-till farming being more natural. It is becoming more common as researchers study its effects and farmers uncover its economic benefits." 06-08

  6. No-Till Farming Advocacy (Grist.org)
      "Mitchell waded into the shoulder-high cover crops of one bed. There’s a bed nearby of cleanly plowed soil. The contrast couldn’t be more different. Mitchell knelt in the cover crop, pushing aside the plants. The earth was covered in a layer of duff (dead leaves and twigs). It looked a lot like — well, like any bit of ground that humans haven’t recently scraped."

      “ 'There’s more organic material going into the soil, more carbon and more nitrogen. There’s more capture of water, and the shade and residue reduces soil water evaporation.' ”
