Carolina Farm Stewardship Association now runs two farm tours per year, one in the Spring and another in the Fall.  The Spring tour has been going on for quite some time, but the Fall tour is in its infancy, this most recent tour being the third annual.

Our first stop this time around was Edible Earthscape, about a half hour drive from our land.  Edible Earthscape, home to a one acre farm intensive incubator farm, is also home to the Piedmont Biofuels Cooperative.  Edible Earthscape is farmed by Haruka and Jason Oatis with the help of several interns.  One of the interns, Brandon, gave us our tour.

On many levels, Edible Earthscape is committed to sustainability and biodiversity within their small farm setup.  Their primary irrigation system uses runoff from the greenhouse stored in a series of 275 gallon totes.

All vegetable rinse water is recycled back into the irrigation system through pipes connected to the wash sinks.

Fall cover crops of cowpeas were recently sown among the freshly mulched raised beds.  Adding leaf litter and other mulches gives our primarily clay soils more “spring” and allows for better drainage.  Over time, heavy mulching also helps with everything from water retention to freeing up nutrients that might otherwise become locked up in the heavy clay.

Bamboo is harvested locally and serves as trellising systems throughout the farm.

The farm focuses much of its energy on Asian heirloom varieties with an added emphasis on seed saving.  Burdock root is grown using a small bamboo chute or trench in order to train the root.  Normal burdock root grows deep and is difficult to remove from our clay soils.  The bamboo chute allows easy access to the root for harvest.

Turmeric (in the ginger family) does moderately well in our climate if removed from the ground and placed in greenhouses to overwinter.

Hops also grow well in our climate, the ones in the picture below were recently harvested for beer brewing.

Flowers add to the biodiversity of the farm both by having the flowers themselves and by attracting beneficial insects.

One of the awesome sights on the farm were the huge trellises of beans, gourds and squashes.  Asian varieties of noodle beans, cucumbers and more formed dense walls of green in contrast to the red clay below.

Add in stevia, borage, Thai bottle gourds, Japanese purple sweet potatoes, echinicea…

A diverse farm is also home to plenty of creatures -

Tomato hornworms (Manduca quinquemaculata) are quick destroyers of the leaves of tomato plants.  They can quickly defoliate entire plants in an organic system.  However, braconid wasps (Cotesia congregatus) will parasitize hornworms in the biodiverse system of yarrows, clovers, and lemon balm that Edible Earthscape has created.

The white cocoons on the hornworm are the developing wasps, which have already started the process of eating their host.  Once most of the wasps emerge, the hornworm will be dead or dying.

What small farm would be complete without a chicken tractor?

And finally the wild edibles that can be found in the places where agriculture is not considered a war on the land.  Winged sumac (Rhus copallinum) supposedly makes a decent lemonade type drink.  Kristin thinks it might be a bit too sour though.
