Cabbage and cauliflower residual biomass spiked with 60% cow dung were vermicomposted for 90 days. Decrease in pH (5.3-9.8%), Total Organic Carbon (36.7- 42.8%); increment in Electrical Conductivity (33-99.4%) and ash content (144.7- 187.8%) were noticed. Significant reduction in C:N ratio (49.5-76.4%) and C:P ratio (62.8-66.04%), increase in Total Kjeldahl Nitrogen (49.3-85.3%), Total Available Phosphorus (68.2-98.1%), Total Potassium (91.8-120.3%) were observed. FT-IR analysis has shown reduction in band heights and peak intensities thus evidenced in organic compound decomposition and vermicompost stability. Germination Index values (98-138%) determined phytotoxicity level. Earthworm growth and prolificacy evaluated via biomass gain (646-809 mg), cocoon number (84-108) and growth rate (2.1-2.7 cocoon/worm). It was inferred that cruciferous vegetable biomass can be used for vermicomposting. Cauliflower residual biomass has shown better decomposition efficiency than cabbage residual biomass.

The exhalation rates of Rn222 (Radon)& Rn220(Thoron) were measured by portable SMART RnDuo (AQTEK SYSTEMS) using a mass accumulation chamber which is equipped with a scintillation material coated cell. Dose rate due to Natural gamma radiations ranged 0.526 to 1.139 mSv y− 1. The Rn222mass exhalation rate in soil samples varied from 0.14 to 94.65 mBq kg− 1 h− 1. Thoron surface exhalation rates ranged 46.42 to 619.88 mBq m− 2 h− 1. This study give an idea about the differences in Rn222 & Rn220 exhalation at different locations which may be due to variations in geological structure of the locations and characteristics of the top soil.The findings show that using soil of the study area as building material is safe.

In order to avoid more stress on the soil plant system, a better understanding of the type of amendments and their integration with the irrigational water quality of any location-specific region is essential. Utilizing salt-affected lands in the best way possible will facilitate food security for the growing human population. An experiment was conducted with the Abelmoschus esculentus L. plant, irrigated with saline water having different NaCl gradients (0, 50, 100 and 150 mM), to evaluate the biochemical and physiological responses under different salinity gradients. Additionally, the effect of compost and vermicompost amendments in soil on plant responses to the changing salinity of irrigated water was observed. The results suggested that the addition of compost and vermicompost in soil not only suppressed the adverse impact of salinity...

The results showed that Eisenia fetida was unable to service in 100% FIS. Addition of some other organic waste to FIS was necessary during vermicomposting. Addition ofFIS with BPS in smaller quantities (20% to 30% on dry weight basis) had no adverse effect on the growth and fecundity of Eiseniafetida because biomass gains by earthworms in 20% FIS was higher than control (100% BPS). The maximum growth rate and cocoon production by Eiseniafetida was 16.21:1:0.64 mg worm-I day-' and 0.21 cocoons worm-I day-I respectively in a 80% BPS + 20% FIS feed mixture. Whereas, minimum growth rate and cocoon production by Eisenia fetid a was 8.14:1:0.32mg worm-I day-Iand 0.07 cocoons worm-I day-' respectively in feed mixture no. 7 (40% BPS + 60% FIS), a higher percentage of FIS in the feed mixture...

In this study, a 13-week experiment was carried to vermiprocess food industry sludge mixed with different bedding materials including two weeds, water hyacinth and parthenium, as well as cow dung, in different combinations employing earthworms of the species Eisenia fetida. Eight vermibins containing one kilogram of the waste mixtures (dry weight basis) were established for vermicomposting. Vermiprocessing significantly increased nitrogen, phosphorous, and potassium contents of the mixtures. However, a decrease in pH, organic carbon, and C:N ratio was observed after vermiprocessing. The heavy metal contents in the vermicomposts were higher than the initial values but within permissible limits. These results indicated that the studied wastes can be converted into good quality manure by vermipr...

A contact time of 120 min and pH 2.0 were found to be optimum. Chromium removal decreased from 90.0 to 45.2% as its concentration increased from 10 to 70 mg/L. The Cr(VI) removal increased from 31.4 to 52.4% as adsorbent dose increased from 4.0 to 20.0 g/L using a test solution having 100mg/L Cr(VI) concentration. Adsorption isotherms were employed to evaluate the maximum adsorption capacity. Adsorption data fitted well to Langmuir isotherm and pseudo-second order model as indicated by high values of correlation coefficient (0.9882 and 0.999) respectively. The adsorption capacity calculated from Langmuir isotherm was 8.177 mg/g.

Two adsorbents were prepared by pre-treating the sunflower stem waste. One adsorbent was prepared by boiling it and second adsorbent was prepared by treating it with formaldehyde. Batch mode experiments were carried out as a function of solution pH, adsorbent dosage, Cr(VI) concentration and contact time. FT-IR spectra and SEMs of the adsorbents were recorded to explore the number and position of functional groups available for the binding of Cr(VI) ions and morphology of the studied adsorbents. The removal of chromium was dependent on the physico-chemical characteristics of the adsorbent, adsorbate concentration and other studied process parameters. Maximum metal removal was observed at pH 2.0. The efficiencies of boiled sunflower stem absorbent and formaldehyde-treated sunflower stem absorbent for the removal of Cr(VI) were 81.7 and 76.5%, respectively for dilute solutions at 4.0g/L adsorbent dose. The applicability of Langmuir, Freundlich and Dubinin-Radushkevich isotherms was also tested. The results revealed that the hexavalent chromium is considerably adsorbed on sunflower stem and it could be an economical method for the removal of hexavalent chromium from aqueous systems.

Vermicomposting process decreased carbon and organic matter concentration and increased N, P and K content in the vermicompost. The C:N ratio was decreased by 45-69% in different vermireactors indicating stabilization of the waste. The heavy metal content was within permissible limits of their application in agricultural soils. It has been concluded from the results that addition of PPVW up to 40% with CD can produce a good quality vermicompost. Whereas, growth and fecundity of E. fetida was best when reared in 20% PPVW+80% CD feed mixture. However, higher percentages of PPVW in different vermireactors significantly affected the growth and fecundity of worms.
