Abstract

This study aims to investigate the possibility of using olive pomace in the preparation of growing substrates for the cultivation of young Quercus suber L. plants in nurseries. It was performed in Guerbes (Skikda, Algeria) where three substrates made from olive pomace, forest humus and a control (forest soil alone) were tested. The obtained results revealed that the S2 substrate (50% olive pomace + 50% humus), by its balanced physicochemical properties (pH= 7.436; EC= 0.17 mmhos/cm; CEC = 79 meq/100g; Organic matter = 6.46 and water retention capacity= 28.66) represents the best substrate because the young plants raised in this substrate for four months recorded the best results in terms of height (16.136cm), diameter (0.249cm), fresh weight of the aerial part (2.090g), fresh weight of the root part (10.230g), dry weight of the aerial part (0.960g) and dry weight of the root part (3.930g).
