This work studied the use of waste from the breeding of broiler on different types of bedding material (straw or sawdust) and its mixture with two commercial peat substrates (black peat and Sphagnum peat). The aim of this study was to achieve the formulation of substrates for the production of ornamental plants, which would reduce the use of peat as the major substrate. Physical and hydrophysical characterization were carried out on two types of materials: manure from the breeding of broiler on straw and broiler on sawdust. Each material was mixed with black peat and Sphagnum peat at 0 and 10 % (v/v). In relation to the physical and hydrophysical properties of the substrates studied, results showed a low bulk density, a high porosity and excessive water retention. From the curve humidity to low suctions, it was found that the mixtures had a good aeration capacity. This aeration capacity of all of the mixtures was greater than 20, except for the substrate obtained by mixing 90 black peat and 10 broiler sawdust. Moreover the water easily usable and the water buffering capacity is poor in water and hardly usable water is very high. Finally, the R parameter (cm of water column height to which the parameter volumes of water and air are equal), show that these substrates have sufficient water easily usable.
