Globally, there are a number of treatments indicated for the control of invasive alien plant species like parthenium. The production and use of vermicomposts from weeds or other wastes in agriculture is economical and eco-friendly. The unique advantage of using vermicomposting is that it helps to build and sustain soil condition and fertility for sustainable agricultural activities. The present...

Pharmaceuticals can enter the soil environment when animal slurries and sewage sludge are applied to land as a fertiliser or during irrigation with contaminated water. These pharmaceuticals may then be taken up by soil organisms possibly resulting in toxic effects and/or exposure of organisms higher up the food chain. This study investigated the influence of soil properties on the uptake and de...

It is known that in vermicomposting soil layer in bedding of the reactor helps in earthworm biomass growth and reproduction but growth is influenced by soil characteristics such as texture, pH, and water holding capacity. The present study was conducted to asses the influence of soils on earthworm biomass growth and reproduction during the vermicomposting of source separated human faeces. The s...

Current bioremediation techniques for petroleum-contaminated soils are designed to remove contaminants as quickly and efficiently as possible, but not necessarily with postremediation soil biological quality as a primary objective. To test a simple postbioremediation technique, we added earthworms (Eisenia fetida) or wheat (Triticum aestivum) straw to petroleum land-farm soil and measured biolo...

The generation of harmonics through a nonlinear mechanism driven by bunching at the fundamental has sparked interest in using this process as a path toward an X-ray free-electron laser (FEL). An important issue in this regard is the sensitivity of the nonlinear harmonic generation to wiggler imperfections. Typically, linear instabilities in FELs are characterized by increasing sensitivity to bo...

Acid rain is still an issue of environmental concerns. This study investigated the impacts of simulated acid rain (SAR) upon earthworm activity from the Latosol (acidic red soil). Laboratory experiment was performed by leaching the soil columns grown with earthworms (Eisenia fetida) at the SAR pH levels ranged from 2.0 to 6.5 over a 34-day period. Results showed that earthworms tended to escape...

The process of vermicomposting with Eisenia fetida has been regarded as a viable solution to the frequent disposal and waste of used coffee grounds. The effects of coffee grounds on earthworms have yet to be fully understood. In a manipulative experiment with varying ratios of coffee grounds and earthworms, we investigate how the amount of coffee grounds affect total earthworm biomass and also ...
