“…Here, surface application rates were positively correlated with SOC and total N in the top 15 cm soil layer, somewhat deeper than other studies reporting that SOC and N gains are limited to the top <10 cm of soils [24][25][26][27]. The current results underscore the fact that the effects of application rate and duration on SOC and total N stocks can be highly variable and depend on biosolids-specific composition as well as site-specific factors (e.g., soils, management) [5,7,28].…”

Mid-to long-term impacts of land applying biosolids will depend on application rate, duration, and method; biosolids composition; and site-specific characteristics (e.g., climate, soils). This study evaluates the effects of surface-broadcast biosolids application rate and duration on soil organic carbon (SOC) stocks, soil aggregate stability, and selected soil hydraulic properties in a municipally operated, no-till forage production system. Total SOC stocks (0-45 cm soil) increased nonlinearly with application rate in perennial grass fields treated for 8 years with 0, 20, 40, or 60 Mg of Class B biosolids (DM) ha −1 yr −1 (midterm treatments). Soil organic C stocks in long-term treatment fields receiving 20 years of 20 Mg ha −1 yr −1 were 36% higher than those in midterm fields treated at the same rate. Surface-applying biosolids had contrasting effects on soil physical properties. Soil bulk density was little affected by biosolids applications, but applications were associated with decreased water-stable soil aggregates, increased soil water retention, and increased available water-holding capacity. This study contrasts the potential for C storage in soils treated with surface-applied biosolids with application effects on soil physical properties, underscoring the importance of site-specific management decisions for the beneficial reuse of biosolids in agricultural settings.

“…Agriculture conservation practices such as the use of different cropping and plant-residue management as well as organic management farming can enhance soil carbon storage. Soriano-Disla et al (2010) discussed the contribution of a sewage sludge application to the short-term carbon sequestration across a wide range of agricultural soils. Tian et al (2009) reported that a mean net SCS of 1.73 Mg C ha -1 year -1 derived from a 34-year reclamation using sewage sludge on strip-mined lands.…”

Soil carbon sequestration: an innovative strategy for reducing atmospheric carbon dioxide concentration

et al. 2012

Global warming due to increasing greenhouse gases emission and the subsequent climatic changes are the most serious environmental challenges faced by environmental scientists, academicians, regulatory agencies and policy makers worldwide. Among the various greenhouse gases, CO 2 constitutes a major share and its concentration is increasing rapidly. Therefore, there is perhaps an urgent need to formulate suitable policies and programs that can firmly reduce and sequester CO 2 emissions in a sustainable way. In order to combat the predicted disaster due to rising CO 2 level, several CO 2 capture and storage technologies and medium are being widely pursued and deliberated. Among them soil carbon sequestration (SCS) is gaining global attention because of its stability and role in long-term surface reservoir, natural low cost and eco-friendly means to combat climate change. Apart from the carbon capturing, the process of soil carbon stabilization also provides other tangible benefits that includes achieving food security, by improving soil quality, wasteland reclamation and preventing soil erosion. The present article aimed to address all these concerns and provide strategies and critical research needs to implement SCS as a mitigation option for increasing atmospheric CO 2 level and its future directions.

“…Whilst its composition is dependent on wastewater treatment processes, in general terms, is characterized by high levels of organic matter, organic nitrogen, P, Fe and Zn (Fytili & Zabaniotou, 2008). Precisely for these characteristics, when SS is applied as an amendment, it enhances soil fertility and SOM levels, as well as potentially contributes to the short-term carbon sequestration (Soriano-Disla et al, 2010). Consequently, the preferred end use of SS in the EU is found in the agricultural sector, applying to the lands more than 30% of the total production (>10·10 6 t on dry basis) (Mahmoud et al, 2012).…”

Energy crops cultivation is expected to further increase, which represents an opportunity to establish synergies able to enhance key environmental components (i.e. soil). To reach this benefits crop management is crucial and should be properly assessed. The aim of this work is to provide an insight on the effects of sewage sludge compost (SSC) on soil properties, when this material is applied as basal dressing for the cultivation of a Mediterranean energy crop (Cynara cardunculus L.). A 3-years trial (2008/2011) was conducted in Alicante (Southeastern Spain), testing four SSC application rates (0, 30, 50 and 70 t/ha) on a heavy textured Anthrosol. The addition of SSC enhanced soil fertility, primarily increasing organic carbon (Cox), Kjeldahl nitrogen (Nk), available P (PBurriel), CuDTPA and ZnDTPA levels. Comparatively with the control (0 t/ha), 30, 50 and 70 t/ha treatments induced a rise of 11%, 19% and 25% in Nk (Control=1.11 g/kg) and PBurriel (Control=79 mg/kg), while for Cox (Control=11.8 g/kg) was 14%, 21% and 30%. However, these variables apparently did not significantly decrease throughout the experiment, which suggests that the organic matter added was under a stabilization process, favoured by the poor physical properties of the soil. Other elements (NaNH4Ac, KNH4Ac, MnDTPA) were accumulated within the soil as time passed by, as a result of soil status, Mediterranean environmental conditions and crop management. The use of SSC as organic fertilizer represents an effective option to optimize cynara cultivation systems while improving soil quality through enhanced long-lasting organic matter pools.
