Earth Day: Recycling Tires for Your Garden

"There's a lot of material going to the landfill that could be used as amendments to soil," Edwards says. "We're earmarking it for research, as well as working with recycling companies to provide a market for their materials."

Finally, from the the same university that alerted us to the fact that Kingsbury Non-Alcoholic Malt Beverage was the beer that attracted snails the most, Colorado State University is now maintaining that a little sparkling water will do wonders for your tomato plants. First-year results showed a 9 percent yield increase in tomatoes irrigated with sparkling water, according to horticulturist Frank Moore.

The plants were mulched with agricultural black plastic, and water enrished with carbon dioxide was piped through drip irrigation tubing. The gas escaped through holes in the mulch to form a "column" of carbon dioxide around the plants. The technique improved plant photosynthesis and reduced the soil pH, resulting in optimum plant growth.
