“…In a recent study about the effects of 40, 80 and 120 Mg/ha of a composted solid waste applied on a degraded semiarid shrubland site, Cuevas et al (2000) reported an elevation of the concentrations of total Zn, Pb, Cd, Ni in the amended soil similar to that in the control. These authors emphasized that these increases were only significant for total Zn, Pb and Cu, while for soil DTPA-extractable Zn and Cu there was high significance in the amended soil.…”

A study was performed to evaluate the pH and the availability of Zn, Cu, Mn, Pb, and Ni in soil amended with increasing doses of composted solid wastes, collected in Rio de Janeiro, Rio de Janeiro State and in Coimbra, Minas Gerais State, Brazil. The influence of the time elapsed between compost application to the soil and the sampling of the plant growth substrate (soil + compost) for pH and metal availability analyses was also examined. The availability of heavy metals in the soil, in the compost and in the substrate was evaluated using DTPA solution for metal extraction. The increase of the compost doses added to the soil resulted in the increase of the pH in the substrate. The addition of the compost from the bigger city, Rio de Janeiro, resulted in higher increase in soil pH and available Zn, Cu, Pb, and Ni levels as compared to the addition of the compost from the smaller city, Coimbra. Increasing the time elapsed between the compost application to the soil and the sampling of the mixture resulted in higher available Zn, Cu, Mn, and Pb levels. The addition of the compost from Rio de Janeiro resulted in substrate metal concentrations in the order Zn > Pb > Ni > Cu > Mn and for the Coimbra compost the metal concentrations in the substrate was Zn > Pb > Cu > Ni > Mn. The higher values of pH and available metals obtained for the bigger city were attributed to the greatest metal contamination of its compost.

“…A reduction in species richness of vegetation communities due to compost amendment was also reported by Cuevas et al (2000). In addition, compost was also demonstrated to negatively influence the establishment of perennial rather than annual species (Cuevas et al 2000;Duan et al 2012;Tarrasón et al 2014). Although the structure does not vary, the overall properties of the vegetation communities are heavily influenced by the fertilization practices.…”

“…In this context, the lower number of species observed on the compost-amended soils could be related to a greater competition, because of the higher number of individuals and/or biomass per unit area. A reduction in species richness of vegetation communities due to compost amendment was also reported by Cuevas et al (2000). In addition, compost was also demonstrated to negatively influence the establishment of perennial rather than annual species (Cuevas et al 2000;Duan et al 2012;Tarrasón et al 2014).…”

“…Indeed, it is known that compost application improves several physical and nutritional soil properties (Hargreaves et al 2008;Diacono and Montemurro 2010), that could affect positively seed germination, shoot emergence, and root growth ( Van-Camp et al 2004). An increase in biomass of spontaneous plant species following soil compost amendments was already reported and attributed to the positive effects of compost not only on the soil chemical properties, but also on the physical and biological ones (Cuevas et al 2000;Tandy et al 2011). Improvements in chemical and biological properties of the studied soil following compost amendments were already highlighted, together with a low pollution risk (e.g., heavy metal and NO 3 -) Saviello et al 2013).…”

“…The positive effects of compost amendments on the physical, chemical, and biological properties of soil are widely documented (Hargreaves et al 2008;Baldantoni et al 2010a, b;Diacono and Montemurro 2010;Morra et al 2010), as well as the interactions among compost amendments and soil properties (Bellino et al 2015). Known are also the effects of compost amendments on the growth of few spontaneous plant species (O'Dell et al 2007) or plant groups (Ohsowski et al 2012) in degraded soils, but much less investigated are the effects on the whole vegetation community (Cuevas et al 2000;Tandy et al 2011;Tarrasón et al 2014). The natural revegetation plays numerous key roles in the recovery of degraded soils, improving many soil chemical, physical, and biological properties, aiding to stabilize or biodegrade pollutants, and, from an ecological point of view, promoting the natural community successions needed for the sustainable recovery of such areas.…”

A vegetation analysis was carried out on a degraded agricultural soil of the Mediterranean area (Campania region, southern Italy) in order to study the effects of different fertilization practices (quality compost, mineral fertilizers, mixed fertilization, and no fertilization) on the whole spontaneous vegetation community. The study was performed for two consecutive years at three different scales (species level, community structure, and community properties), using three different units of abundance (number of individuals, biomass, and cover of each species). The observations were carried out in spring, after 5 and 6 years of soil treatments, on a total area of 4 m(2) for each soil treatment and in each year. The different fertilization practices did not determine changes in species composition; however, the relative abundance of dominant species increased in compost and mixed fertilized soils, particularly in the second year of observation. Although the dominance and diversity were unaffected by the different fertilization practices, the total biomass and total number of individuals increased in compost-amended soils. These results indicate the effectiveness of soil quality compost amendments to enhance natural revegetation, a key step in the recovery of degraded areas.
