The reconstitution is a pedotecnique producing environmental proper and fertile Technosols, applying chemical-mechanical treatment to alluvial sediments, degraded soils and pedomaterials included waste by different productive processes. By the means of reconstitution the environmental restoration of the covering degraded soil of a closed landfill near Piacenza is made (LIFE10 ENV/IT/000400 NEW LIFE). In order to assess this environmental restoration, LCC and FCC are calculated on 5 soil samples before and after reconstitution. The results, which highlight the transition from IV, VI and VII to II in LCC classes, and from III and V to I in FCC, show how reconstitution was able to convert the environmental and agronomic conditions from soil have very severe limitations that restrict the choice of plants or require very careful management, or that make it generally unsuited to cultivation and that limit or restrict its use mainly to pasture, range, forestland, or wildlife food and cover, to soil have moderate limitations that restrict the choice of plants or that require moderate conservation practices or have optimum fertility. LCC is used to classify lands; the limitation made up by low productivity, due to soil chemical fertility (pH, C.E.C., organic matter, salinity, degree of saturation) is related to morphology, climate and vegetation of the area where soil is. FCC is used to evaluate soil fertility, not in relation to morphology or evolution, but on the bases of physico-chemical properties of the 0-20 cm soil layer. On the basis of pH, organic matter, total CaCO3, exchangeable K2O, P2O5 a modification of FCC is used to calculate an indicator of global soil fertility.
