“…In the peat amendment study, increased reproduction was observed when the OM content was increased, although the pH of the soil decreased from 5.2 to 4.4. In general, the effect of soil pH on oribatid mite abundance seems to be species specific with some species exhibiting narrow tolerance thresholds and some having relatively wider tolerances [42,43]. In addition to OM content, we also found that the use of an age-synchronized culture reduced the reproduction variability for this species.…”

Few soil invertebrate species are available for the toxic assessment of soils from boreal or other northern ecozones, yet these soils cover the majority of Canada's landmass as well as significant portions of Eurasia. Oppia nitens (C.L. Koch) is an herbivorous and fungivorous oribatid mite found in soil throughout Holarctic regions, including Canada. Soil tests using O. nitens were performed using 15 different forest soil types and horizons to investigate test variability in adult survival and reproduction. Adult survival (86.1 +/- 1.1%) was consistent across soil types, with a coefficient of variation (CV) of 15%. However, reproduction varied significantly, ranging from 2.9 (+/-1.1) to 86.2 (+/-11.7) individuals, with a corresponding CV of 118 and 30%, respectively. Of the soil factors assessed (NH(3), NO(3), pH, phosphorus [P], organic matter content (OM), carbon:nitrogen (C:N), sand, silt, clay, and sodium adsorption ratio), soil organic matter (OM) explained 68% of the variation observed for reproduction. Increasing the OM using Sphagnum sp. peat moss resulted in optimal reproduction at 7% OM (8% peat content) with the lowest variability (CV of 20%). When assessing the toxicity of a reference chemical, boric acid, the effect of peat amendment reduced lethality to adults with no observable difference on reproduction. The use an age-synchronized culture reduced the test variability for reproduction relative to the use of unsynchronized cultures. Oppia nitens is a good candidate species for a standardized test design, with adult survival easily assessed in a relatively simple design. A long-term reproduction test with O. nitens will require the use of a synchronized population and, on occasion, OM amendment when testing soils with low organic matter content.

“…However, when fertilisation has stopped, a recovery of faunal abundances, or even an increase, has often been seen (Behan et al, 1978;Abrahamsen and Thompson, 1979;Huhta et al, 1983). Several studies have shown clear relationships between mesofauna and pH (Hutson, 1978;Hågvar and Abrahamsen, 1980;Hågvar and Amundsen, 1981;Huhta et al, 1983;Huhta, 1984) and decreases following large applications of fertilisers, often urea, have partly been attributed to pH effects. Urea commonly causes an increase in soil pH whereas addition of ammonium nitrate causes a slight decrease in pH (Huhta et al, 1983.…”

“…The clarification of these aspects thus needs further research. This is underlined by the interspecies variability in soil pH preferences of soil arthropods [75,76]. Acidity could be a stress factor especially under drought conditions [77], but the pH values are still above 7, and thus, this effect is not expected to be relevant in the two investigated sites.…”

Effects of Olive Mill Wastewater on Soil Microarthropods and Soil Chemistry in Two Different Cultivation Scenarios in Israel and Palestinian Territories

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 OPEN ACCESSAgriculture 2015, 5 858 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.
