Valorization agricultural of a solid digestate avicolous resulting from the industrial biomethanisation in Tunisia

Abstract

The use of the Peat (T) mixed with of methacompost of poultry (MCA) with / without addition of crude forestry compost (CSB) in the substrate of culture prepared has been an experiment in soilless nursery. The growth and survival of tomato plants, among other things, were studied in two experiments, one mixes on MCA + T and the other on mixtures CSB + T + MCA, as compared with the reference substrate (T). The tests performed confirmed that the incorporation of MCA and CSB with T provides slightly better growth in height of tomato plants while limiting bleeding Force by imports of peat substrates. Statistically, there was not observed a significant difference between the height of plants. Height growth of tomato plants was influenced by the type of partial substitute. In this regard, we find that plants grown on substrates mixture have stunted growth due to the apparent phytotoxicity of methacompost of poultry, physical quality and especially its water unsuitable behavior.
