Abstract
Intensive agriculture or phenomena such as pollution, compaction, and/or erosion lead to a decrease in the amounts of organic matter of soils; thus, causing a decrease in their fertility. The use of an organic amendment in agriculture could combat soil degradation. In this sense, two organic amendments with olives waste (OW) and olive mill wastewater (OMW) have been manufactured. The objective of this work is to examine the capacity of these amendments to improve soil quality in comparison with manure (M). Three types of soil were tested: the first has been amended for two years with a compost of similar composition (S 1 ), the second not amended (S 2 ), and the third corresponds to an agricultural soil that is amended with chemical fertilizer (S 3 ). All the trials were carried out on two vegetable gardens: potato and radish. The ANOVA shows that the amendment effect was highly significant on all the physicochemical parameters studied except humidity. In conclusion, this product could be an alternative to chemical fertilizers and considered as a perennial solution adapted to the context of sustainable development to the recovery of olive waste.
