“…Other researchers indicate that the use of the highest sewage sludge rates significantly improved soil chemical parameters already in the first year of growth. However, in the subsequent years, the beneficial effect of high sewage sludge rates on soil chemical composition becomes less evident (Alvarenga et al, 2017).…”

“…After three years of growth, the amount of mobile P 2 O 5 in the topsoil layer increased approximately 12 times to 933-984 mg kg -1 . Usually, different sewage sludge materials contain high amounts of phosphorus (Alvarenga et al, 2017). It is a good alternative for traditional mineral phosphorus fertilization, particularly for energy crops, since inorganic phosphorus resources on the Earth are quite limited (Linderholm et al, 2012).…”

In order to estimate the effect of granulated sewage sludge on the productivity of the cup plant (Silphium perfoliatum L.), soil physical and microbial properties, a field experiment was carried out in Western Lithuania, on a naturally acid moraine loam Bathygleyic Dystric Glossic Retisol with a pH of 4.3-4.9. The dry matter yield of the cup plant consistently increased over the experimental years from 2.83 t ha -1 (in 2013) to 12.86 t ha -1 (in 2016). Each year, the optimum sewage sludge rate for dry matter yield of cup plant was 45 t ha -1 . The use of both sewage sludge rates 45 and 90 t ha -1 had a similar and positive impact on soil chemical composition, water-stable aggregate formation, topsoil bulk density, soil penetration resistance and moisture content. Each experimental year, the application of sewage sludge at a rate of 90 t ha -1 had the strongest impact on the increase in soil microbial biomass carbon at the 0-30 cm depth. Experimental results suggest that when growing cup plant as an energy crop on a moraine loam Retisol, it is expedient to use granulated sewage sludge at a rate of 45 t ha -1 .

“…Estimated hazardous concentrations (HC) using either median effect concentration (EC50; HC50 EC50 and HC5 EC50 ) or EC10 (HC50 EC10 and HC5 EC10 ) data in % of waste and tonnes/hectare a Total metal concentrations in each raw waste and expected concentrations for each HC concentration are also presented (raw waste metal concentrations obtained fromAlvarenga et al 2017). In terms of legislation, AIS is considered a sludge, and the remaining wastes (MMSWC, AWC, AWSSC, and PMW) are classified as fertilizer materials.…”

The use of organic wastes as soil amendments can be an important measure to improve soil quality and reduce waste accumulation and landfilling. However, the potential contaminant loads of such wastes, can be a source of environmental concern. Consequently, legislation has been developed to regulate the use of these wastes in agricultural soils. However, the regulations only consider chemical parameters, which are insufficient to establish the level of environmental risk. A possible solution is the use of species sensitivity distributions (SSDs), employing ecotoxicological data from test batteries that could be incorporated into legislation. In the present study, 2 different hazardous concentrations affecting 5 and 50% of the soil community (HC5 and HC50, respectively) were determined using ecotoxicological data (effect concentrations, 10 and 50% [EC10 and EC50, respectively]) for 5 different wastes. The results demonstrate that, as expected, current legislative thresholds do not translate to environmental risk/protection and that SSDs may be an important tool allowing the simple inclusion and interpretation of ecotoxicological data from test batteries in legislation. On the other hand, SSDs must be used with caution because there are still doubts about their actual value in risk prediction and about which estimates provide adequate protection. For instance, the use of HC50EC10 values is not recommended; these values overlap with the more conservative HC5EC50 data, highlighting the fact that the use of lower effect concentrations may not always provide the most protective approach. Also, hazardous concentrations need to be calibrated at the field or semifield level, to verify environmental protection in different soils/environments and the adequacy of standard test organisms.
