Organic farming practices boost soil carbon, structure
Review of nine studies shows strong soil organic matter gains despite cultivation for weed control.
Organic management enriched soilcarbon and nitrogen in particulate organic matter by 30 to 40 percent relative to the conventional controls, according to data from a paper in a 2006 edition of the Soil Science of America Journal. The authors reviewed soil samples from nine farming system trials comparing organic (using legume and manure sources for nitrogen) and non-organic farming methods.
Theorganic systems had higher soil organic carbon levels and total nitrogen concentrations than conventionalsystems whether or not manure was applied. They found that the particulate organic matter levels of carbon and nitrogen did not differ significantly between manure with legumev. legume-based organic systems.
