AGRONOMIC VALUATION OF OLIVE POMACE OBTAINED BY DIFFERENT EXTRACTION SYSTEMSHalima Ameziane, Abderrahman Nounah1, Mohammed Rachid Kabbour and Mohamed Khamar
Olive pomace from the three extraction systems: the traditional press system, the two-phase continuous system and the three-phase continuous system from the city of Tahla (Morocco), have significant levels of nitrogen and phosphorus fertilizers, a large amount of organic matter and a slightly acidic pH (5.9). Their contribution to the sandy soil of SalÃ© city has a positive effect on stem size, number of leaves and leaf area of bean plant. The addition of pomace has increased the dry matter weight of the aerial parts of the bean. However, the large proportion of these olive pomace is generally not properly valued. The comparative study of the pomace obtained by different extraction systems gave a particularity to the pomace from the two-phase system, given its richness in fertilizing elements; in fact it allowed an optimal development of Vicia fabae.
