Organic Science Project

Critics often ask where the research is on organic techniques. Well, there’s plenty of it. Check out the research center on DirtDoctor.com.

Let me tell you about one research project - my daughter Logan’s science project. In the seventh grade, Logan’s science project was about the growth- enhancing properties (or lack) of lava sand. She planted radishes and ebon rye both from seed in 6” pots. I don’t recommend sterile potting soil normally, but I did in this case so that the fertility would be low and have nothing to do with the growth of the plants. Half of the pots had nothing but the potting soil. The other half had one added ingredient - lava sand. The lava sand made up about 20% of the potting soil volume. All pots were watered the same. The day before the project was due, the pots were photographed and some of the plants were removed. The tops of the radishes were about the same in the control and the lava. The grass in lava pots was taller and greener, but the roots of both groups of plants were significantly bigger in the lava-amended potting soil.

The following year the test was repeated using garlic planted from cloves. Success again – lava sand won. Did the lava provide some

special fertility? No. Lava is solid volcanic rock called scoria. It’s the low level natural energy called paramagnetism that made the difference. Lava is one of the best organic tools we discuss and recommend. Only those living on volcanic land don’t benefit from the addition of volcanic sands. Like most of the tools we use, lava works best when used with other organic products. Other staple products include compost, greensand, molasses and cornmeal – all the alternatives to toxic chemicals.
