“…Generally, FA contains potentially toxic elements such as As, Cu, Zn, Cd, Pb, Ni, Cr, Se, etc. (Adriano et al 2002;Rautaray et al 2003;Lee et al 2006;Tiwari et al 2008;Nayak et al 2014), which readily contaminate soil. At higher levels of FA, some toxic elements might become more active and hinder microbial activity (Adriano et al 1978).…”

Thermal power stations apart from being source of energy supply are causing soil pollution leading to its degradation in fertility and contamination. Fine particle and trace element emissions from energy production in coal-fired thermal power plants are associated with significant adverse effects on human, animal, and soil health. Contamination of soil with cadmium, nickel, copper, lead, arsenic, chromium, and zinc can be a primary route of human exposure to these potentially toxic elements. The environmental evaluation of surrounding soil of thermal power plants in Odisha may serve a model study to get the insight into hazards they are causing. The study investigates the impact of fly ash-fugitive dust (FAFD) deposition from coal-fired thermal power plant emissions on soil properties including trace element concentration, pH, and soil enzymatic activities. Higher FAFD deposition was found in the close proximity of power plants, which led to high pH and greater accumulation of heavy metals. Among the three power plants, in the vicinity of NALCO, higher concentrations of soil organic carbon and nitrogen was observed whereas, higher phosphorus content was recorded in the proximity of NTPC. Multivariate statistical analysis of different variables and their association indicated that FAFD deposition and soil properties were influenced by the source of emissions and distance from source of emission. Pollution in soil profiles and high risk areas were detected and visualized using surface maps based on Kriging interpolation. The concentrations of chromium and arsenic were higher in the soil where FAFD deposition was more. Observance of relatively high concentration of heavy metals like cadmium, lead, nickel, and arsenic and a low concentration of enzymatic activity in proximity to the emission source indicated a possible link with anthropogenic emissions.

“…Ash also has a liming effect by increasing base saturation, cation exchange capacity, and pH of forest soils (Ingerslev et al, 2014). However, neither major increases in heavy metals nor negative effects to the microbiological processes in soil have been attributable to soils amended with wood ash (Makela et al, 2012;Nayak et al, 2015).…”

Pulp and paper mill waste, such as biomass fly ash and sewage sludge, is commonly disposed of in landfills. This waste can be valuable as nutrients and C sources for degraded soils. Ash and sludge samples were chemically characterized before ash/sludge pellets were experimentally manufactured for use as soil amendment. An incubation experiment was carried out with controlled moisture and temperature; nutrient input and N mineralization were evaluated at 0, 15, 30, 45, and 60 d intervals using three pellet types with different proportions of ash, sludge, and gypsum (as a binder) and applied at four doses equivalent to 0, 10, 20, and 40 Mg ha -1 . Results indicated that the Alfisol that was amended with pelletized residues increased P Olsen and exchangeable K and Ca contents, as well as soil pH (p < 0.05) in direct response to the applied doses. Organic matter decreased during incubation at all the doses and pellet types (p < 0.05); however, N mineralization did not show a clear pattern during incubation. Nitrogen mineralization potential (N 0 ) was different depending on pellet types and application rates; Pellet 2 (10% sludge) exhibited the highest N 0 values, while Pellet 3 (20% sludge) had lower N 0 than the control. Pulp and paper mill waste can be used to amend degraded soils by creating sustainable use through pelletizing because it facilitates transport and can evenly distribute sludge and ash on soils in a single application.

“…The availability and uptake of HMs in plants is affected by a variety of factors such as pH, redox potential, solubility, contents of OM, soil mineralogy, texture and chemical speciation of the metal (Čásová et al, 2009;Nayak et al, 2015). Some researchers have showed that OM contributes to the reduction of metal availability by decreasing the labile metal in soil (Gao et al, 2003).…”

The proposal to use sewage sludge (SS) on agricultural fields as a sustainable way to dispose of the waste is based on its high organic and nutrients content. However, the presence of heavy metals (HMs) in sludge can contaminate crops and accumulate in the food chain. The aim of this study was to assess changes in soil fertility, biochemical responses of tomato (Solanum lycopersicum L. cv. Rio Grande) seedlings and the availability of HMs with increased rate application of SS (0, 2.5, 5 and 7.5%). Leaf chlorophyll content, nutritional status, proline, membrane peroxidation, stomatal conductance and HM accumulation were investigated. Results showed that the soil pH decreased, whereas soil salinity, organic carbon, total N, available P and exchangeable Na, Ca, K and HM content increased significantly with increasing application rates of SS. Among the three HMs (Zn, Cu and Cr), Zn had the highest capacity for transferring from soil into plants. Low metal translocation was observed from roots to leaves. The 7.5% SS dose decreased biomass production and caused a decline in chlorophyll content and stomatal conductance. However, lipid peroxidation and proline contents increased. Therefore, the use of 2.5 and 5% doses of sewage sludge in agriculture would be an efficient and costeffective method to restore the fertility of soil and an environment-friendly solution for disposal problems.Additional key words: sewage sludge amendment; soil fertility; biochemical responses; Solanum lycopersicum.
