The surface mining activities in the past and in recent times has resulted into existence of number of overburden dumps through excavation and depositing removed soil and rock debris. These dumps require environmental stabilization/restoration, through proper revegetation. To achieve this aim, a study was conducted to find the efficacy of Mung bean (Vigna radiata L.), an economically important ...

Several technologies are being applied for treatment of palm oil mill wastes. Among them, the biological treatments (vermicomposting) have widely been recognized as one of the most efficient and eco-friendly methods for converting organic waste materials into valuable products. The present study focuses on vermicomposting of acidic palm oil mill effluent (POME) mixed with the palm pressed fibre...

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...

The effects of adding the biosurfactant rhamnolipid, the lignolytic and cellulolytic fungus Phanerochete chrysosporium, and the free-living nitrogen-fixing bacterium Azotobacter chrococcum on vermicomposting of green waste with Eisenia fetida was investigated. The addition of rhamnolipid and/or either microorganism alone or in all combinations significantly increased E. fetida growth rate, the ...

in the recent years, increasing production of waste as a result of population growth, increased food consumption, industrial development and urbanization growth, is regarded as a serious challenge. vermicompost, as an end product of urban waste recycling with proper physicochemical features, can play an effective role in plant growth and development and also in reducing harmful effects of vario...

one of the strategies for improving the quality of agricultural products is using bio-fertilizers. so in order to study the effects of mycorrhizal fungi, vermicompost and humic acid on growth characteristics and yield of fennel, an experiment was studied on research farm of agricultural college of shahrood university. this study was conducted as factorial experiment based on completely randomiz...

Producers in semi-arid and highland regions have difficulty increasing diversity crop rotations due to unfavorable conditions imposed by cool temperatures, inadequate rainfall, shorter growing periods. In such conditions, some cultural practices that increase productivity as fertilization appear a promising alternative. Fertilization the form of fertilizer substantial influence on sunflower (He...

A greenhouse trial assessed the effects of biochar and vermicompost as partial substitutes conventional growing media on leafy vegetables’ yields changes NH 4 + -N NO 3 − in medium leachates. Six mixtures [(a) coir, (b) coir biochar, (c) vermicompost, (d) peat, (e) peat +vermicompost, (f) biochar] combined with three nitrogen (N) rates [0% (0 g N·pot −1 ), 50% (0.5 100% (1.0 ) commercial recomm...
