Permaculture practices effect on soil fertility and organic matter distribution in aggregate-size classes
In identical geopedoclimatic conditions, the authors
compared Soil Organic Matter (SOM) allocation and soil fertility in a pasture
under permaculture with a soil under
conventional agriculture. Permaculture practices increased bioavailable nutrients Ca, Mg, K and P, total nitrogen concentrations and organic carbon stocks, which was explained by the very large manure inputs. Permaculture practices had little
effect on soil aggregation. Permaculture practices may enhance
soil fertility and SOM storage, but further research is needed. In addition, a carbon balance should be performed to determine
if the additional OC storage corresponds to a net sink of CO2.
