Effects of Permaculture Practices on Soil Physicochemical Properties and Organic Matter Distribution in Aggregates: A Case Study of the Bec-Hellouin Farm (France)

The limitations of conventional agriculture have accelerated the need for a transition to an environmentally and economically sustainable agricultural model. Authors aimed to study the impact of permaculture and biointensive micro-gardening practices on soil physicochemical properties and soil organic matter (SOM). The physicochemical properties of soils in permaculture farming implemented for 7 years were compared with a soil under pasture. The concentrations of total OC and nitrogen (N) in bulk soils were higher under permaculture practices, due to significant inputs of manure and compost, resulting in higher concentrations of the bioavailable nutrients Ca, Mg, K, and P. Permaculture/biointensive micro-gardening practices enhance SOM storage and substantially improve nutrient bioavailability.
