Our total growth is in our first picture. The second picture we discovered while taking out the plants an earthworm tunnel. In the third picture is our plants from the pot with the earthworms, the first one has major freeze damage and the other two are new growth after the freeze. The Nodules are from our non earthworm experiment, it was the largest plant and produced these. The self nitrogen producing plant has theses and when cut in half the pink shows that the bacteria is working. The last picture has our plants from the non earthworn pot. The large plant made it through the freeze. After the freeze we planted four new seeds which sprouted, yet the earthworm pot grew more.

Living in Kansas we have learned to expect anything. But this past weekend we were not ready for the unexpected snow. Our greenhouse temperatures reached freezing. One out of four of our soybean plants luckily was hardy enough to make it. Our others unfortunately did not. We have planted four more seeds in the same pots. Our worms should have made it through, we won't know until the end of our experiment.
