Thermal diagnosis and analysis of the silvicultural composting process to prevent the spread of seeds of yellow nightshade (Solanum elaeagnifolium Cav.)

The objective of this work was to study thermogenesis during the process of composting to assess the possibilities of thermal destruction of the germination capacity of seed Solanum elaeagnifolium (SOEL). The spatio-temporal thermal monitoring of the forest compost windrow, where SOEL seed has been introduced, showed a substantially homogeneous distribution of the temperature rising to 60°C and even more along the windrow and for a period of 5 consecutive days. The germination rate was zero for all seeds from berries treated before the first reversal, whatever the depth and location of the windrow at which the berries were introduced. Thus, composting can be an alternative to prevent the spread of SOEL by seed.
