| Abstract | Constructed Technosols are an alternative to the loss of natural soils caused by human activities. The sustainable Technosols management implies that we understand the evolution of their hydrie properties. Here, we analyzed shrinkage curves on technosols with a proportion of compost varying between 0 and 50%, in the presence or absence of plants and/or earthworms. Our results show that these organisms explain better the variance of the hydrie properties (19%) than the compost content (14%).The compost and plants play a positive role on available water present both in macroporosity and microporosity. Earthworms play a positive role only on the latter. The interaction between organisms and compost was more important than the simple effect of each factor (40%). Generally, plants and earthworms show a more positive effect than compost alone. |
