Abstract

Different soils temperature fluctuations - measured in the Year 2013 - are presented. The temperatures of a natural degraded soil and a reconstituted soil - derived by a new degraded and desertified soils treatment for the restoration of fertility - are compared. The reconstitution technology, made by m.c.m. Ecosistemi research laboratory, is based on mechanical and chemical actions working on the soil structure, organic matter disposal and organic carbon policondensation. The reconstituted soils have better physical and chemical characters - including organic matter, porosity, and volumetric water content at different suctions - than the degraded one. The trend of organic matter, porosity and volumetric water content - being closely related to heat capacity, specific heat, thermal diffusivity and thermal conductivity - justify the observed thermal trend. For measuring the soils temperature - at 25 cm depth - two detection probes were used. The reconstituted soils have always less temperature fluctuations than natural one.
