Copper Sucking Corn Cleans Polluted Soil

Copper Sucking Corn Cleans Polluted Soil

In a controlled laboratory experiment, the team introduced copper to pots of normal soil, then inoculated some of the pots with the bacteria. That made all the difference. Corn and maize planted in the contaminated soil did fine in the bacteria-added pots, and horribly in the pots with no bacteria. In fact, the bacteria were such a great help that plants grown in the bacteria-added, copper-tainted soil did almost as well as those grown in normal, healthy soil. In a conversation with CleanTechnica, Wusirika explained that the bacteria contributed growth hormones to the soil and rendered the phosphates soluble, making it easier for the plants to take these nutrients up. The next step is to grow plants in copper-contaminated soil gathered from a site near the village of Gay.
