Driftless Area Land Conservancy, South Iowa Street, Dodgeville, Wisconsin, USA

Regenerate the Earth

Wilson Organic Family Farm is a 7th generation family farm nestled in the Driftless Area of Southwest Wisconsin. An organic farm since 1998, the soil is the base of our ecological farming and stewardship beliefs that food production must occur in sync with nature, wildlife, and the world we share. This philosophy is rooted in our practices from diverse crop rotations that include many diversified perennials to cover cropping and eliminating chemicals and synthetic fertilizers.

Regenerate the Earth

Muff Corp has made numerous operational changes in the last decade for the betterment of their land. A large change was shifting to no till corn and soybeans, including corn on corn, drastically changing their historical tillage practices. In 2015 the farm adapted application of plant food in replacement of old fertilizer practices, creating more emphasis on regenerative fertilizer practices. In addition, the farm now uses numerous species of cover crop practices, grazing cattle on corn stalks and stover to assist with residue management and in turn spread cattle manure as a source of fertilizer and most recently began variable rate seeding practices with technology advancements.

Regenerate the Earth

We started experimenting with cover crops and reduced tillage over 8 years ago. Over the years, we have continued to experiment with new and better ways to apply covers, manage soil health, and create a better growing environment to support the important crops we grow and use to feed our cows.

Regenerate the Earth

We began no-till in the mid 90’s and continued the practice since. Then in 2015, we started incorporating cover crops with no-till to further prevent erosion. Since then, we have been experimenting with best cover crop practices and have now incorporated on almost all acres. In 2019 we started incorporating livestock into our crop acres.

Wausa Farm X Nori

Township 29 N, Range 2 W, Knox County, Nebraska

Regenerate the Earth

Until 2011, the farm had been farmed in the traditional method of plowing, discing, harrowing, planting, cultivating, and then harvesting. In 2011, the Cunninghams gave up their farming activities and leased the land to Roger Blunck. Roger suggested to the Cunninghams that they consider “no-till” farming. The Cunninghams agreed. The farm has been farmed continuously since that year by Roger, and his son, Matt, utilizing “no-till.” Upon our purchase of the land, we leased the land to Roger and Matt, and they have continued the “no-till” practice on the farm. Since 2020, we have added cover crops to the land. We are considering incorporating a small grain crop into the traditional corn soybean rotation. The advantage of “no-till” is in the utilization of the decomposition of the previous year’s crop residue into the soil increasing the health of the soil. Healthy soil increases the activity of earthworms in the soil helping with moisture retention in the soil. Also, the residue, and the additional crop cover, help with soil erosion during periods of heavy rainfall. For so long as we own this farm, we will continue with the “no-till” farming operation to promote the health of the soil and to assist in the annual crop production.

Came Farms Inc X Nori

Came Farms, West Shipton Road, Salina, Kansas, USA

Regenerate the Earth

We have always worked hard to be at the front edge of conservative/regenerative farming practices. We began experimenting with no-till in the early nineties and by 2002 had converted all of our acres to no-till. With no-till, came the ability to graze our cattle on the corn and sorghum stalks after harvest, which we continue to do today. In 2016, we began to utilize variable rate, at first with fertilizer, but later using variable rate for seeding as well.

Vaulted Deep LA Injection Site

Los Angeles, CA, USA

Buries sludgy organic waste.

Vaulted Deep injects organic waste into durable wells, where the carbon in the waste is sequestered as it decomposes. Using a specialized slurry injection technology, their process can handle a wide range of organic carbon sources with minimal energy and upfront processing. Their system has the potential to be deployed quickly at large scales.

Vardar Varme X Carbon Centric Biomass Incineration

Treklyngen, Hvervenmoveien, Hønefoss, Norway

Biochar and carbon credit trader. 

Vardar Varme’s biomass incineration plant is located at the Treklyngen Industry park in Hønefoss, Norway. With a 100,000 tonne capture plant, Carbon Centric will capture more than 90% of the CO₂ emissions from a completely biogenic source. This means the carbon we capture will be removing carbon that already exists as part of the natural carbon cycle, instead of avoiding additional CO₂ emissions.
