“…A comparison of the effects of lime and sewage sludge on all soil variables shows that, initially, the effect of lime was greater than that of sewage sludge, which may be because the lime was responsible for higher inputs of Ca than sewage sludge (López-Díaz et al, 2007;Mosquera-Losada et al, 2011b). However, the effects of sewage sludge were similar to those observed by Mosquera-Losada et al (2011c) in silvopastoral systems established with P. radiata D. Don in acidic soils (3.87) receiving much lower inputs of sewage sludge (50 and 100 kg total N ha -1 ), which indicates that sewage has a higher residual effect than lime (EPA, 1994). The residual effects of the limed treatment gradually declined in the years after its application, as evidenced by the fact that, in the first years of the study (1998)(1999)(2000)(2001), pasture production and tree growth were higher in the limed plots than in those not receiving limed treatment (Mosquera-Losada et al, 2001;López-Díaz et al, 2007), which indicates that the nutrient uptake by the trees and the pasture was higher in the limed plots.…”

In Galician (Spain) silvopastoral systems, nutrient availability to the pasture and trees can be limited by soil acidity. Liming and fertilisation with sewage sludge could enhance the productivity of silvopastoral systems (including understory and trees) by increasing Ca and reducing Al in the soil. This study evaluated changes in soil chemical properties, tree growth and understory production in test plots, both limed and unlimed, in a silvopastoral system located on an acidic forest soil under Pinus radiata D. Don. This research compared the effects of different doses of sewage sludge (160, 320 and 480 kg total N ha −1) with the effects of mineral fertilisation (8% N-24% P 2 O 5-16% K 2 O) and no fertilisation. The initial lime applications improved soil fertility (increasing soil pH, effective exchange capacity, and the saturation percentage of Ca and reducing the saturation percentage of Al) more than the sewage sludge. However, the most significant effects of sewage sludge were found over the long term after high doses of sewage sludge were applied (480 kg total N ha −1). Therefore, the use of sewage sludge as a fertiliser improves both soil fertility and the productivity of silvopastoral systems in the long term as long as an adequate disposal of this residue is guaranteed.

“…Furthermore, the most significant variation in understory vegetation in the forest with sludge addition was the enhancement of coverage [49]. Moreover, in the SS fertilization of forests, it has been demonstrated that the understory biomass is increased [50][51][52]. An obvious observation regarding understory herbs in the Mongolian pine plantation during this study period was that there were significant differences between the SL and CK treatments, especially during summer (Figure 6).…”

The application of domestic sewage sludge (SS) may affect plant growth and soil quality through altering nutrient availability. However, the effect of SS application on the plant–soil system in sandy soils is poorly understood. In this study, we established SS application treatment plots (SL, 25 t ha−1) and control treatment plots without sewage sludge application (CK, 0 t ha−1). SS was applied to the soil surface of a Mongolian pine (Pinus sylvestris var. mongolica) plantation in Horqin Sandy Land, Inner Mongolia, China, to assess its potential effects on plants and soil. We analyzed tree growth performances (tree height, basal diameter, and diameter at breast height), understory traits (species diversity, coverage, and aboveground biomass), soil physical and chemical parameters (nutrient content, dissolved organic carbon, soil water content, bulk density, pH), and proxies of ecosystem services (soil organic carbon and total nitrogen stocks). The results showed that SS addition not only significantly increased soil nutrient contents, but also markedly enhanced aboveground productivity and plant coverage. Specifically, SS addition decreased soil bulk density and increased concentrations of soil organic carbon, total nitrogen, and total phosphorus and mineral nitrogen, and it also increased soil carbon and nitrogen stocks. Furthermore, the addition of SS significantly increased soil dissolved organic carbon contents and enhanced the fluorescence intensities of dissolved organic carbon components (humic acid-like and UV fulvic acid-like) in the topsoil (0–5 cm). This study provides evidence that SS is an acceptable, and possibly preferred organic fertilizer for improving the soil quality and tree–grass growth of Mongolian pine plantations.

“…Thus, the negative growth effects of control soil and soil amended with a low SS application rate were likely related to soil nutrient deficiencies. Firstly, the initial C/N ratio was 13.1 which is not enough for nitrification rate to provide an adequate supply of nitrogen to plants ( Mosquera-Losada et al 2011). SS tended to enhance the initial potential mineralization both in stable and labile stable OM pools, which represents an advantage in acidic soils in which coniferous forests induce low organic matter decomposition.…”

Cu, Zn, Pb, and Cd concentrations in a soil plant (Lactuca sativa) continuum were measured after sewage sludge amendment. The effects of sewage sludge on growth and trace metal bioaccumulation in snails (Cantareus aspersus) were investigated in a laboratory experiment specifically designed to identify contamination sources (e.g., soil and leaves). Application of sewage sludge increased trace metal concentrations in topsoil. However, except Zn, metal concentrations in lettuce leaves did not reflect those in soil. Lettuce leaves were the main source of Zn, Cu, and Cd in exposed snails. Bioaccumulation of Pb suggested its immediate transfer to snails via the soil. No apparent toxic effects of trace metal accumulation were observed in snails. Moreover, snail growth was significantly stimulated at high rates of sludge application. This hormesis effect may be due to the enhanced nutritional content of lettuce leaves exposed to sewage sludge.
