At Work: Fresh Harvest in February

I live on Camp Pleasant Road, but on most days, I'm in Frankfort working for Kentucky State University as a research assistant in Organic/Sustainable Vegetable Production. We do a lot of interesting work there, and I can't help but share some of it on this blog. This may not have happened at Camp Pleasant, but some things are related. . .

Last November, as winter was setting in, we took a large portion of our sweet potato harvest and buried it deep in the ground. We had a bit of help from John Clay, a working farmer in his eighties, who claims to be the last colored farmer in Franklin County. (I'm sure that the inevitable BOOM that farming is about to have will change that!) John told us about vegetable storage pits that his parents used to use when he was growing up. Large parts of Kentucky didn't get electricity until the 1950's or so, so many people grew and stored their own food without refrigeration. You can see a video of the construction of our pit on our Kentucky State University Organic Agriculture Working Group website:

Just a few days ago, I dug into the soil and found our pit of potatoes and straw. I was amazed. While winter froze and thawed, and dropped inches of snow and ice through December and January, the soil had insulated our pit and preserved a large percentage of our harvest. Below are some pictures.


This is the pit. The blue tarp covered the pit from November to February, and helped keep moisture from getting into the sweet potatoes. The pit is designed to insulate vegetables from freezing, and to keep them in a dry bed of straw or sand.

As you can see, our pit was covered with about 2.5 feet of soil. It is a lot of work to dig into a pit like this...but it is rewarding. Digging into a pit like this is an amazing experience, and it makes it clear why people built root cellars...you only have to dig once!

Clean, dry, live sweet potatoes...


This picture shows the amount of good potatoes and the amount of rotten potatoes. Not bad, if you ask me. Many of the good potatoes had bruises that we had to cut out before cooking. But the taste was everything you'd expect from a sweet potato.
We have about 10X as much as this buried in our pit, and we hope to keep many of them alive until time for replanting in spring!

We also buried temperature-taking probes inside the pit, and we will publish the winter temperatures at different levels in the pit, alongside outside air and soil temperatures, on the KSU Organic Working Group's website.

Garden/Farm: The Hoop House is Ready!


Yesterday, I put the finishing touches on our little hoop house. It is made of used lumber from our land, wood from dumpsters, new cattle panel fencing (for the structure), used irrigation tape and hoses, and new plastic.
With this tunnel, we can start seedlings, and extend the season by planting early or planting late. A hoop house collects and traps solar heat. There is nothing heating this house but the sun.

Below are some detailed images for those interested. This entire 10 x 30 tunnel was constructed for about $250.


Inside the house, we've put down a mulch path and a nice layer of compost. The mulch was given to us by the utility company, who dumped huge loads of it on our land when they were trimming trees on our road. The compost is from a company that blends yard "waste" from Lexington with horse manure and straw from thoroughbred farms.

This is a good view of the cattle panels. We used eight of these fence-building panels to build the structure of our tunnel. They were easy to bend, and we simply attached them to large boards that are anchored in the ground a bit by wooden stakes.







We used one large piece of plastic to cover almost all the tunnel. It wraps around the end of the tunnel, where we attached some used irrigation line to the cattle panels to keep the plastic from rubbing on the rough edges of the panels.

Here, you can also see that the plastic is attached by a black line of T-tape...another piece of used irrigation. T-tape is excellent for this. We simply stapled through the T-tape and plastic, and into the wood.





















Here's a picture of the wire we used to keep things together. It is super useful
and with a fence tool, you can twist the wire up
and connect just about anything.









This is my favorite part. I had a hard time making the door flush with this design. And any crack lets in a lot of cold air, cooling the tunnel very quickly. With a hoop house, we want to TRAP heat.

Instead of heading to the hardware store, we go to the old barn and hunt for things to use. For this, we found an old hose.






This is a corner of the tunnel. If you look closely, you'll see a little piece of "wiggle wire", which is something used on "real" high tunnels. These pieces were salvaged from a tunnel that was destroyed in a storm.

Wiggle wire allows you to fasten plastic with a wiggly wire into a track. Here, we are using it to secure our roll-up sides. We can remove the wire, making the roll-up side loose, and we can roll it up to the level of the black T-tape to ventilate the tunnel.


See...roll up sides...Inside the plastic is a long pole made from pieces of bamboo tied together with fencing wire. We can roll these sides up and attach them from the inside with little ties.



















Trouble shooting...inside the tunnel, we had some gaps where the bamboo poles didn't quite touch the ground. So I plugged these holes with a fun-noodle. Fun noodles were never really that much fun, anyway. Around here, we prefer inner tubes for floating in the river.














...Looking forward to planting leeks, broccoli, and greens!

Please don't hesitate to contact me if you want to chat about this design...

Paul and Allison are excellent high tunnel growers in western Kentucky.

Good Foods Coop, in Lexington, are currently looking for a farmer or two to provide lettuce mixes through the winter. "We could sell tons of the stuff...all you could grow..."
