虽然橄榄厂废水（OMW）经常被应用到土壤中，已知具有植物毒性，但其对土壤动物的影响仍然未知。本研究的目的是调查如何OMW蔓延在橄榄园甲螨和弹尾目群落，土壤理化性质和它们之间的相互依赖性。为此，我们用OMW处理了两个研究中心（Gilat，Bait Reema）的地块。除其他外，这些地点在灌溉方法、土壤类型和气候方面存在差异。我们观察到，土壤酸度和防水性的发展，以较低的程度在Gilat比诱饵Reema。这可以通过灌溉引起的稀释和Gilat中OMW化合物的沥滤来解释。在诱饵Reema，OMW应用抑制出现甲螨，并引起社会的转变，但丰富的弹尾目增加OMW和水处理的地块。在Gilat，OMW应用后甲螨丰度增加。OMW应用对土壤生物区系的影响是由于生物活性的刺激和有毒化合物对敏感物种的抑制之间的相互作用。环境和管理条件与影响的程度和持久性有关。此外，这项研究强调，需要详细研究的生态毒理学效应的OMW在不同的应用率。
Although olive mill wastewater (OMW) is often applied onto soil and is known to be phytotoxic, its impact on soil fauna is still unknown. The objective of this study was to investigate how OMW spreading in olive orchards affects Oribatida and Collembola communities, physicochemical soil properties and their interdependency. For this, we treated plots in two study sites (Gilat, Bait Reema) with OMW. Among others, the sites differed in irrigation practice, soil type and climate. We observed that soil acidity and water repellency developed to a lower extent in Gilat than in Bait Reema. This may be explained by irrigation-induced dilution and leaching of OMW compounds in Gilat. In Bait Reema, OMW application suppressed emergence of Oribatida and induced a community shift, but the abundance of Collembola increased in OMW and water-treated plots. In Gilat, Oribatida abundance increased after OMW application. The effects of OMW application on soil biota result from an interaction between stimulation of biological activity and suppression of sensitive species by toxic compounds. Environmental and management conditions are relevant for the degree and persistence of the effects. Moreover, this study underlines the need for detailed research on the ecotoxicological effects of OMW at different application rates.
