Research on the reuse and recycling of agricultural by-products and industrial wastes are becoming increasingly important due to storage and environmental problems associated with these wastes. This study investigated the effect of olive oil solid waste (OSW) application rates on the macro- and micro-elemental contents and plant growth of bean (Phaseolus vulgaris L.) and sunflower (Helianthus annuus L.) and soil properties. OSW was mixed with soil at rates of 0, 3, 5 and 7% w/w. Sunflower was grown for 45 days and bean for 30 days in pots. Relative phosphorus (P), calcium (Ca), zinc (Zn) and boron (B) contents by mass of sunflower plants increased while nitrogen (N) and carbon
