“…Bioassays have been used to study soil contamination by organic waste amendments using higher plants, like oat (Avena sativa) and turnip (Brassica rapa) (Gong et al, 2001;Riepert and Felgentreu, 2002). However, few works have reported the use of bioassays using soil animals to test impacts of sludges and compost applications on soil.…”

Aiming to evaluate a possible loss of soil habitat function after amendment with organic wastes, a digested sewage sludge and derived composts produced with green residues, where biologically tested in the laboratory using soil animals (Eisenia andrei and Folsomia candida) and plants (Brassica rapa and Avena sativa). Each waste was tested mimicking a field application of 6ton/ha or 12ton/ha. Avoidance tests did not reveal any impact of sludge and composts to soil biota. Germination and growth tests showed that application of composts were beneficial for both plants. Composts did not affect earthworm's mass increase or reproduction, but the highest sludge amendment revealed negative effects on both parameters. Only the amendment of composts at the highest dose originated an impairment of springtails reproductive output. We suggest that bioassays using different test species may be an additional tool to evaluate effects of amendment of organic wastes in soil. Biological tests are sensitive to pollutants at low concentrations and to interactions undetected by routine chemical analysis.

“…in [30]. Incubation (conditioning) under moist condition does [63] or does not ( [40], West et al, 1986) allow the restoration of the soil microbial parameters. For instance, [19] showed that the soil microbial respiration and C biomass retrieved values similar to those of fresh soils after a few days of pre-incubation under moist condition, even for 36-years old soil samples [23].…”

Abstract. This review aims to determine the impact of soil storage on microbial parameters (abundance/biomass, activity and various diversity metrics). We analysed the literature dealing with the impact of storage practices (cold, freeze, dry, freeze-dry and ambient storage) on soil microbial parameters. A total of 73 articles were included in the analysis, representing 261 basic data (impact of a given storage practice on a microbial parameter). Globally, 74 % of these data showed significant impact of storage on the measured microbial parameters, as compared to those measured on fresh, non-stored soil samples. The storage practices showed various effects on the soil microbial parameters, with sometimes opposite effects across different soil types. For instance, various soil enzyme activities did not respond the same way to storage practices, even in a given soil type. There are currently too few studies to draw recommendations, but some studies suggest that the pedoclimatic context could be useful for choosing the best storage option, with soils that regularly undergo drought or freezing being less impacted by dry and freeze storage, respectively. I conclude that storage practices for soil samples, when unavoidable, should be carefully selected according to conditions that prevail in the native soil environment, to microbial parameters that are analysed (even though there is no consensus for a best practice), and with different storage practices for different microbial parameters if necessary.

“…If the plants grow badly in the controls it is difficult to identify effects occurring in the test vessels with test soils. For this reason, Riepert and Felgentreu (2000) recommended to avoid the use of fresh field soils because they don't contain enough available nitrogen due to high microbial activity. In order to solve this general problem fertilizer could be added to the water reservoirs used in the plant tests.…”
