Influence of Moisture on the Activity of Perionyx Excavatus (perrier) and Microbial–nutrient Dynamics of Pressmud Vermicompost
Moisture play a crucial role in vermicomposting of pressmud (filter cake) (P). Five levels of moisture contents of pressmud (55-57%, 60-62%, 65-67%, 70-72% and 75-77%) at 31±2°C on earthworm activities (growth, reproduction and recovery rate of vermicompost) of Perionyx excavatus (Perrier)-an indigenous species and total microbial population, activity and nitrogen, phosphorous, potassium conten...

Although many species could be used for these ends, given their nutritional requirements and reproductive biology, only Perionyx excavatus and Lampito mauritii are widely used. The most effective use of earthwor...
متن کاملVermicomposting of Sugarcane Trash and Leaf Litter in Combination with Pressmud Using the Earthworm, Perionyx ceylanensis
In the present study, initial vermicomposting trials were conducted for 100 days using leaf litters of Polyalthia longifolia (LPL) and sugarcane trash (SCT), each in combination with pressmud (PM) (i.e., 0:100, 25:75, 50:50, 75:25 and 100:0) by inoculating an epigeic earthworm, Perionyx ceylanensis. Based on C/N ratio, worm biomass and numbers recorded in vermicomposting trials, organic substra...
