Abstract:
In order to replace peat in container media with organic materials of local origin, their physical properties should conform with those of peat to support optimal plant growth. The main physical attributes of several peat samples of various origins were characterized in relation to their water holding capacity and volumetric free air space at container capacity. The results are presented in the form of water release curve diagrams. Similarly, a peat substitute produced by composting the coarse fraction of cattle manure was characterized. The results are presented and discussed in relation to their effect on optimal irrigation management.
