It Takes a Community of Soil Microbes to Protect Plants from Disease

http://www.sciencedaily.com/releases/2011/05/110505161001.htm

ScienceDaily (May 7, 2011) — Those vegetables you had for dinner may have once been protected by an immune system akin to the one that helps you fight disease. Scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the Netherland’s Wageningen University found that plants rely on a complex community of soil microbes to defend themselves against pathogens, much the way mammals harbor a raft of microbes to avoid infections.

The scientists deciphered, for the first time, the group of microbes that enables a patch of soil to suppress a plant-killing pathogen. Previous research on the phenomenon of disease-suppressive soil had identified one or two pathogen-fighting microbes at work.

But the Berkeley Lab-led team found a complex microbial network. After analyzing soil from a sugar beet field that had become resistant to a pathogen that causes root fungus, the scientists found 17 soil microbes fighting to suppress the pathogen. They also determined that all of the microbes work together to reduce the incidence of fungal infection. Their discovery that plants use a tight-knit army of soil microbes for defense could help scientists develop ways to better protect the world’s food crops from devastating diseases.

“Individual organisms have been associated with disease-suppressive soil before, but we demonstrated that many organisms in combination are associated with this phenomenon,” says Gary Andersen of Berkeley Lab’s Earth Sciences Division. He conducted the research with fellow Berkeley Lab scientists Todd DeSantis and Yvette Piceno as well as several scientists from the Netherlands including Wageningen University’s Jos Raaijmakers. Their research is published in the May 5 issue of Science Express.

The Soil Foodweb

“Soil Foodweb Technology is based on years of research by many different people. All science builds on previous science, the efforts of scientists to understand why the world works the way it does. Science is an on-going process of quantitative assessment and understanding of mechanisms on which life is based.”

These world wide lavatories for soil testing, research and eduction are the brain child of Dr.  Elaine R. Ingham.

What is compost tea?
“Compost tea is an aerobic water solution that has extracted the microbe population from compost along with the nutrients. In simple terms, it is a concentrated liquid created by a process to increase the numbers of beneficial organisms as an organic approach to plant/soil care.”

This company offers soil information and products like Tea Brewing system, Bio-Amendments, Books and CD.
