Organic Farming Builds More Soil Organic Matter Than No-Till

I am glad to have some proof on this, at last.

Organic Farming Builds More Soil Organic Matter Than No-Till

A long-term study by USDA's Agricultural Research Service shows that
organic farming can build even more soil organic matter than no-till
farming practices. The study showed that organic matter added by manure and
cover crops more than offset any organic matter losses due to tillage
to control weeds. The research is reported in the July 2007 issue of
Agricultural Research
(http://www.ars.usda.gov/is/AR/archiv...7/soil0707.htm) magazine.
