“…Therefore, the physico-chemical properties of TICA significantly differ from those of thermal power plant CA (TPCA). Earlier, we have identified the potential of CA for agricultural application as a nutrient source [5,6]. However, long-term application of CA may lead to severe contamination because of the presence of toxic compounds.…”

Overload of coal ash (CA) generated from several coal fired plants poses acute problems of disposal and contamination of soil and water resources. Since CA generated from tea factories has not yet been characterized from environmental viewpoints, we attempted to critically characterize the agro-ecological compatibility of CA samples (CA1, CA2, CA3, and CA4) collected from four distantly located tea factories. Among these samples, we found CA3 and CA4 to have low pH and high metal content. Accordingly, we restricted our study to predict the solubility pattern of non-metal and metal ions in CAs by adopting a geochemical model (Visual MINTEQ). Various fractions of metals like Fe, Mn, Cu, Zn, Cr, Ni, and Pb were studied to figure out the mobility pattern of metals in the environment. The results clearly indicate that tea industry derived CA substantially differs from thermal power plant CA as regards several physico-chemical properties, for example, sandy texture, low pH and high nutrient content. Risk evaluation of human exposure to trace elements and the metal fractionation study led us to conclude that CA1 and CA2 are highly compatible with agricultural use.

“…Lee (1992) reported that the organic materials pass through the gut of earthworms then some of phosphorus being converted to such forms that are available to plants. Mineralization and mobilization of Phosphorus due to bacterial and earthworm's activity may be responsible for increase in TAP (Goswami et al 2013).…”

Purpose Parthenium hysterophorus is one among the most troublesome weeds at the global level. It is mainly controlled by chemical methods. The scientific community is in search of new but non-destructive approaches for its management. Vermicomposting is one among the promising technologies for the management of organic fraction of solid wastes. This study was undertaken to assess the vermicomposting of parthenium weed mixed with biogas plant slurry under laboratory conditions. Method Six different combinations of biogas plant slurry and parthenium were fed to worms in vermibins under controlled laboratory conditions for 60 days. Various physico-chemical parameters before and after vermicomposting were evaluated. Worm biomass production was also monitored periodically during the experimentation period. Results The EC, TCa and NPK content increased significantly after vermicomposting, accompanied by substantial reduction in organic carbon content. C: N ratio was reduced to less than 20. Heavy metals (Fe, Zn, Ni, Cu, Cr and Pb) concentration was higher in vermicompost than in initial waste mixtures. Parthenium weed addition to worm feed was not supportive to the worm growth and fecundity.It was inferred from the results that vermicomposting may be an efficient biological approach to convert partheniumspiked biogas plant slurry into nutrient-rich manure.

“…The continuous application of brewery wastewater has been reported to have the potential of improving soil physical and chemical characteristics and increase the contents of organic carbon and nitrogen with beneficial effects on soil quality more evident on poorly developed soils -sandy soils [12][13][14][15][16]. Continuous effluent application on soil can also lead to an increase in level of sodium and consequently the electrical conductivity of the soil [13,15].…”

“…In this regard, some studies have indicated that some sludge effluents such as paper industry sludge would require to be treated before using them for improving soil quality while others (such as sewage plant treatment sludge effluents) even though have high nutrient value contains high concentration levels of heavy metals and therefore would still be treated before application [16,17].…”

This study reports the residual effect of Ama Brewery effluent sludge discharge on the soil quality of the recipient soil environment in Amaeke Ngwo Community of Udi Local Government Area of Enugu State Nigeria. Samples were collected in triplicates in two sites, control and test sites and analyzed the physical and chemical properties of the soils. The result of analysis showed that some soil chemistry parameters such as phosphorus, calcium, potassium, magnesium, organic matter, organic carbon, cation exchange capacity and exchangeable bases occurred at higher levels of concentration in the test soil site than the control site. This study therefore indicates that the Ama Brewery sludge effluent has not impacted on the soil quality of the test site adversely but has improved it for agricultural purposes. The distribution of the measured soil chemistry parameters is such that the top soil contains the highest concentration. The study also revealed that the movement and distributions of these parameters down the soil profile could be modeled via predictive models that would however require to be validated with data from other field studies.
