“…The addition of MSW compost had favorable effects on soil biological activity, as it increased dehydrogenase activity at both doses, although biomass-C content was only higher for SC2 (Table 5). This is in agreement with results from several experiments that have demonstrated that soil biological properties such as microbial biomass C and enzymatic activities are significantly improved by compost addition (Paradelo et al 2007(Paradelo et al , 2009bHargreaves et al 2008;Diacono and Montemurro 2010). This effect of compost on biological activity is attributed to an increase in substrate availability to decomposer microorganisms, since they use organic carbon for energy trough respiration or for assimilation into their tissues.…”

Purpose A field trial was conducted on a silty-loam soil under potato culture in NW Spain, to assess the effect of municipal solid waste (MSW) compost in a heavily fertilized acid soil. Methods Three doses of compost (0, 30 and 60 Mg compost ha −1 soil) or inorganic fertilization (~ 140 N: 120 P 2 O 5 : 240 K 2 O kg ha −1 soil) were assayed. The effects of compost on soil physical, chemical (nutrient status and potentially toxic trace elements) and biochemical properties were evaluated after 1 and 5 months. Results Compost addition at the highest dose decreased bulk density and increased soil porosity and soil stability against water erosion. Soil pH, total organic C and N, cation exchange capacity and available P, Ca, Mg and K were also higher in compost-amended soils, whereas no effect on NH 4 + -N and NO 3 − -N was observed. Compost significantly increased soil microbial biomass and dehydrogenase activity. Due to the high nutrient status in the control soil, potato yield was not increased by compost or inorganic fertilization. A negative consequence of compost addition was the increased extractability of trace metals such as Zn, Cu, Pb and Ni, although their total concentrations in soil or in potato tubers did not increase with respect to the control. Conclusions Overall, results show that positive effects of MSW compost can be expected even in rich soils that do not need fertilization for maintaining their productive function in the short-term. These positive effects prove the benefits of recycling urban wastes in agricultural soils as a sustainable way of waste management.Publisher's Note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.

“…Then 2500-3000 g of each of the three mixtures were placed in plastic containers (0.4 m length, 0.15 m width and 0.15 m height) and watered to circa 70-80% of their field capacity, which was calculated on the basis of similar mixtures prepared for previous experiments (Paradelo et al, 2007). The mixtures were incubated at 25°C in the laboratory for 90 days, plus a control consisting of SPF without any amendment.…”

“…in greenhouse experiments, only if amended with a material capable of increasing the water holding capacity and supplying essential nutrients (Paradelo et al, 2007). In this work, two grape marc composts were used as amendments of SPF during a laboratory incubation experiment in which the chemical and biological properties of various mixtures were monitored.…”

“…Improvements in soil water holding capacity, total porosity, plant‐available water and water content at matric potentials greater than −100 kPa as a result of applying different types of compost have been found (Barzegar et al. , 2002; Paradelo et al. , 2007; Weber et al.…”

The objective of this study was to investigate the effects of the long-term addition of three compost types (vegetable, fruit and yard waste compost - VFYW, garden waste compost - GW and spent mushroom compost - SM) on the physical properties of a sandy soil and to quantify any such effects using indicators of soil physical quality. Soil samples were taken from a field with annual compost applications of 30 m3/ha for 10 yr and various physico-chemical analyses were undertaken. Results show a significant increase in soil organic carbon (21%) with the VFYW and GW compost types. With SM, soil organic carbon increased by 16%. Increased soil macroporosity and water content at saturation with a corresponding decrease in bulk density were observed for all compost types. However, quantification of these improvements using existing soil physical quality indicators such as the 'S-index', soil air capacity and matrix porosity gave mixed results showing that these indices perform poorly when applied to sandy soils. It is concluded that the long-term application of compost does not significantly improve the physical properties of sandy soils, but the absence of adverse effects suggests that these soils are a viable disposal option for these composts, but new indices of quality are needed for the proper characterization of sandy soils
