    Behavior Of Acacia Plants Installed On Substrates Based On Compost Sylvicole With Or Without Methacompost Of Poultry In A Modern Nursery In Tunisia
    (University of Eloued جامعة الوادي, 2013-01-01) M’sadak, Y.; Ben M’barek, A.; Tayachi, L.
    The present study aims principally the evaluation of germination and of plant growth of Acacia cyanophylla installed, on the one hand, on the gross forestry compost (CSB) in its purest form, produced in a forest nursery in Tunisia, on the other hand, on the CSB mixed with poultry methacompost (MCA) refined (solid residue from the industrial digester) in its two states, namely the output of the decanter (MCAA) and the outlet of the digester (MCAA') according to the same ratio, of 20 %. Both tested mixtures were the best, due to the direct assessment of physico-chemical properties of various mixtures made. The incorporation of the MCA with the CSB has a notable positive effect on germination, and consequently on the growth of Acacia seedlings in terms of height and diameter. The CSB presented an intermediary vegetative behavior.

    Monitoring And Thermal Analysis Of Co-composting Process In A Forest Nursery Modern (tunisia)
    (University of Eloued جامعة الوادي, 2013-01-01) M’sadak, Y.; Saad, I.; Saidi, D.
    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 temperatureshowed 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.
