| Abstract:
The aim of this work is to establish the physical and chemical properties of olive marc, an organic by-product obtained in olive mills, in order to see if it can be composted, and after stabilization, used as a substrate for horticultural plants. Analytical determinations were done with fresh and composted materials. The composting process had an influence on both chemical and physical properties. The particle size decreased whereas bulk density, water retention and water absorption capacity increased. As a result, composted materials had a low total pore space. The use of olvie marc as an horticultural substrate and the improvement of the water-air relation in composted materials, using mixtures with other substrates, are discussed. | |
