SUIVI ET ANALYSE THERMIQUES DU PROCESSUS DE CO-COMPOSTAGE SYLVICOLE DANS UNE PEPINIERE FORESTIERE MODERNE (TUNISIE)

The objective of this work was to study thermogenesis during the process of Co-composting to assess the possibilities of thermal destruction of the germination capacity of weeds seeds. A regular monitoring of temperature has been achieved, using a probe thermometer, at nine locations of heap crafted. The outlines of temperature profiles allowed the identification of the four phases of the process, from a temperature monitoring, which is taken twice a day. The mid-monthly monitoring of temperature showed no significant differences for the first three dates of monitoring, whatever the depth and whatever time study. The bi-monthly monitoring showed insignificant differences for the first three dates, whatever the depth of the heap and whatever the studied time. The last three dates showed insignificant differences for the time of recording, whereas for the depth, the results obtained were significant.
