The aim of this work was to study the effects of agronomic application of olive mill wastewater (OMW) in a field of olive trees on olive fruit and olive oil quality. Agronomic application of OMW increased significantly the fungal:bacteria ratio, whereas the root colonisation and the photosynthetic rates decreased significantly. Consequently, the oil content expressed as a percentage of dry weight, decreased significantly after agronomic application of OMW. Land spreading of OMW altered the relative proportion of individual olive fruit sugar and decreased significantly the nitrogen (N) and phosphorus (P) of the fruit. A significant increase was observed in total phenol content of oil after agronomic application of OMW. alpha-Tocopherol content, on the contrary, decreased with OMW application. The fatty acid composition of the oil was not affected by the treatments. To our knowledge, this is the first report of change in the olive fruit and olive oil quality following agronomic application of OMW.
本研究旨在探讨橄榄果渣废水（Olive Mill Wastewater，OMW）在橄榄田中的农业应用对橄榄果实和橄榄油质量的影响。农业应用橄榄果渣废水显著增加了真菌与细菌的比值，而根系定植和光合速率则显著降低。因此，在农业应用橄榄果渣废水后，油含量以干重的百分比表示，显著降低。土地散布橄榄果渣废水改变了个体橄榄果实糖的相对比例，并且显著降低了果实中的氮（N）和磷（P）。农业应用橄榄果渣废水后，油中的总酚含量显著增加。相反，α-生育酚含量随着 OMW 的应用而降低。油的脂肪酸组成不受处理的影响。据我们所知，这是首次报道农业应用橄榄果渣废水对橄榄果实和橄榄油质量的影响。
