| Abstract:
Some physical parameters were determined on an organic product derived from a new phytodewatering process of sewage sludge, in order to verify its possible use as a substrate for plant growth. Wetting-drying cicles were carried out with a sandy soil and mixtures (1:1 w/w) of this soil with the organic product taken before and after the phytodewatering process. After the second and the fifth cycle the water stability and the strength of soil aggregates, together with penetrability, bulk density and total porosity, were determined on soil and mixtures. The phytodewatering process increased the total porosity, water stability and friability. | |
