Influence of organic products incorporation on reconstituted anthropogenic soil physical properties
Abstract
In order to study the evolution of added organic matter in controlled conditions, we worked with three types of organic products. Each was incorporated in 20% or 40% by volume in a loamy soil, and then incubated at 28°C and 18% humidity during 55 days. Before and after the incubation period, we compared the carbon granulometric fractionation, and we showed that there was a physical fractionation of the carbon. The porosity decreased during the 55 days, but the image analysis highlighted the pore space reorganization. The tests of structural stability was rather inconclusive.
