Organic Soil – good for the earth, good for the atmosphere

Phil Robertson may be on the cusp of solving a long-standing mystery.

Boosters of organic food often say the practice, which rejects synthetic fertilizers and pesticides, is a good method for curbing climate change because it stores more carbon in the soil. But aside from anecdotal observations, no one could really explain the dynamics behind why organic fields keep more carbon underground than conventional ones.

Robertson, a researcher at Michigan State University’s Kellogg Biological Station, thinks he might have an answer: a chemical group called phenolics, a class of complex compounds that also protect plants from disease and pests.

In understanding the role phenolics play, Robertson’s findings could lead to a better understanding of how to cut emissions from the global agriculture sector.

The idea that organic agriculture keeps more carbon underground is not a novel one, Robertson said. But the fact that legumes may produce a disproportionate amount of phenolic compounds may be unique. Robertson plans to publish the findings in the coming year.

I was born in Croatia, at that time Yugoslavia. My family moved to the US when I was very young, but I still treasure the memories of my grandfather teaching me how to protect myself against the "evil eye," my grandmother shopping early every morning, at the open air market, to buy the freshest vegetables for the day's meals, and the traditions that were the underpinnings of our society. Someone once noted that "For all of us that want to move forward, there are a very few that want to keep the old methods of production, traditions and crafts alive." I am a fellow traveler with those who value the old traditions and folk wisdom. I believe the knowledge they possess can contribute significantly to our efforts to build a more sustainable world; one that values the individual over the corporation, conservation over growth and happiness over wealth.
