“…In the humid tropics, the use of organic composts to maintain SOM is widespread (Lasaridi and Stentiford 1998;French et al 2006;Hartley et al 2008), particularly in urban environments where conditions for plant growth are challenging. The benefits of applying organic composted materials to soils are widely acknowledged internationally (Amlinger et al 2007;Lillenberg et al 2010), and it has been found to facilitate increases in organic matter content, biological activity and nutrient supply to plants (Zhang and Selim 2008;Tandy et al 2009). These effects, however, are typically short-lived in the tropics due to high rates of SOM decomposition and frequent compost application used to negate this effect.…”

Research relating to the use of organic amendments on soils has focused largely on agricultural soils, and there is a lack of information worldwide on their efficacy as amendments for urban soil management, especially in tropical urban environments. A pot experiment was conducted to assess the influence of biochar and organic compost on urban soil properties and on tree growth performance in Singapore. Biochar and compost were mixed with topsoil in different proportions, and two urban tree species commonly grown in Singapore (Samanea saman and Suregada multiflora) were used. There were significant additional height increments for both the tree species following application of biochar. S. saman exhibited greater stem elongation compared with S. multiflora in response to organic amendments. A significantly higher foliar N content was found in both tree species in biocharamended treatments along with significant increases in P and K. Increases in soil nutrient concentrations were also observed in combined biochar-compost treatments for both species. Combined compost and biochar had the strongest effects on soils and growth of the two urban tree species examined and applications containing biochar resulted in the most significant soil improvements.

“…Ceccanti et al ( 2006 ) found signifi cant hydrocarbon reduction in soil treatments using a combination of compost and earthworms ( Eisenia fetida ), both regulating the biochemical equilibrium of the soil. Tandy et al ( 2009 ) recommended co-composting as a sustainable management option for remediating mine soil polluted with metals (Cu, As, Zn and Pb). Cai et al ( 2007 ) investigated the effi cacy of four different composting systems to bioremediate sewage sludge contaminated with PAHs.…”

Pollution and the global health impacts from toxic environmental pollutants are presently of great concern. At present, more than 100 million people are at risk from exposure to a plethora of toxic organic and inorganic pollutants. This review is an exploration of the ex-situ technologies for cleaning-up the contaminated soil, groundwater and air emissions, highlighting their principles, advantages, deficiencies and the knowledge gaps. Challenges and strategies for removing different types of contaminants, mainly heavy metals and priority organic pollutants, are also described.

Assessing the influence of technosol and biochar amendments combined with Brassica juncea L. on the fractionation of Cu, Ni, Pb and Zn in a polluted mine soil

Purpose Soil metal pollution is a widespread problem around the world and remediation of these soils is difficult. The objective of this study was to investigate the effect of two different strategies on the chemical fractions of metals in a soil of a depleted copper mine: (1) amending with a mixture of a technosol made of wastes and biochar and (2) amending combined with planting vegetation (Brassica juncea). Materials and methods A 3-month greenhouse experiment was carried out to evaluate the effects of organic amendments and vegetation on the metal fractionation of Cu, Ni, Pb and Zn in a mine soil of the depleted copper mine at Touro (Spain). We compared the influence of organic amendments alone (technosol + biochar) and combined with mustard plants (Brassica juncea L.). Results and discussionThe results showed that amending with a technosol made of wastes promoted plant growth (from 0.7 to 2.9 g of biomass produced) and reduced the CaCl 2 -extractable metal concentration in soil, reduced the mobility factor of Cu from 18.3 to 1.6, Ni from 47.5 to 2.3 and Pb from 17.9 to 2.1, and also reduced the concentration of metals in the mobile soil fractions. It was not possible to grow up Brassica juncea plants in the untreated settling pond soil due to the extremely degraded conditions of that soil. However, the application of the used technosol increased the Pb and Zn pseudototal concentrations in the amended soils. Conclusions We conclude that the combination of amending with wastes and planting B. juncea provides little additional benefit for remediating a metal-polluted soil compared with incorporation of wastes alone.
