“…Strategies based on changes in land use and agricultural management addressed in increasing the C stored in the tree biomass and into the soils have been reported to be potentially important to reduce atmospheric CO 2 (Jarecki and Lal, 2003; Gómez et al, 2009). Among the agricultural managements, the addition to soil of organic wastes as amendments derived from various sources represents an efficient practice to increase soil organic C content in the agro-ecosystems (Mondini and Sequi, 2008; Sánchez-Monedero et al, 2008; Lozano-García et al, 2011; Bedbabis et al, 2015; Proietti et al, 2015; Russo et al, 2015). Furthermore, this strategy would bring other desirable benefits, such as enhancement of soil structure, increase soil fertility, and decrease soil erosion rate (Sánchez-Monedero et al, 2008).…”

The soil amendment with organic wastes represents a way to increase the soil fertility and the organic carbon (C) stored in the agro-ecosystems. Among the organic waste materials produced by agricultural and industrial activities, olive mill wastes derived from the olive oil extraction process may represent a suitable soil amendment. The aim of the study was to evaluate the effect of fresh (SOMW) or composted mixture of SOMW and shredded olive tree prunings (C-SOMW+P) on the vegetative and productive activities of olive trees, on the C stored in the tree non-permanent structures (prunings and fruits) and in the soil. The plots treated with SOMW or C-SOMW+P showed higher vegetative and productive activities than the untreated plots, and this was attributed to the higher total N and availability of P and K supplied by the amendments. Consequently, treatments increased the C sequestered in the tree non-permanent structures than in the control trees. However, no significant different effect between SOMW and C-SOMW+P treatments was found for the C stored in prunings and fruits, whereas it was evident a stronger influence of C-SOMW+P than SOMW on soil C sequestration. Indeed, about 50% the C supplied by the treatment with C-SOMW+P was sequestered in the olive grove system, with more than 90% of the sequestered C stored into the soil. The low amount of C sequestered in the soil following the addition of SOMW was attributed to its richness of moisture and easily degradable compounds that triggered the mineralization processes controlled by the soil microbial community. Although the 8 years of amendment produced a higher fruit yields than the control, no difference occurred between the characteristics and the oil content of the olive fruits. Only the total phenol content for the oil obtained from the SOMW-treated plots was significantly higher. The other considered fruit characteristics did not show significant differences.

“…Results of some researches indicated that using marginal waters like industrial wastewater and saline groundwater as irrigation water caused yield reduction of plants such as corn, olive, cucumber and grapevine (Amer 2010;Kang et al, 2010;Wan et al, 2010;Ben Ahmed et al, 2012;Bame et al, 2014). Impacts of wastewater irrigation on soil chemical components have been reported by Sou/Dakouré et al (2013) and Bedbabis et al (2014Bedbabis et al ( , 2015. The increase of soil salinity and sodicity and decrease of soil infiltration rate has been observed by Bedbabis et al, 2014 after long-term irrigation with wastewater.…”

“…The increase of soil salinity and sodicity and decrease of soil infiltration rate has been observed by Bedbabis et al, 2014 after long-term irrigation with wastewater. Researchers concluded that irrigation with hyper sodic wastewater destroyed soil structure especially in sub-horizon of soil (Sou/Dakouré et al, 2013;Bedbabis et al, 2014;Bedbabis et al, 2015). Researchers have investigated wastewater application effects on soil ions concentration of Na + , Ca + , Mg + , K + and on heavy metals accumulation in the soils and plant tissues.…”
