“…The reductions in TOC, lignin, and cellulose were greater in the vermicompost than in the aerobic compost. The faster decomposition of green waste with vermicomposting than with aerobic process can be explained by the fragmentation of organic matter by earthworms, which increases the surface area of the organic matter and thereby increases the quantity of organic matter accessible to microorganisms and microbial enzymes [ 20 ].…”

This research was conducted to compare chemical and microbiological properties during aerobic composting (AC) and vermicomposting (VC) of green waste. Relative to AC, VC significantly decreased the pH and lignin and cellulose contents, and significantly increased the electrical conductivity and total N and available P contents. For AC, BIrii41_norank (order Myxococcales) was the major bacterial genus at 30 d and again became dominant genus from 90–150 d, with relative abundances of 2.88% and 4.77–5.19%, respectively; at 45 d and 60 d, the dominant bacterial genus was Nitrosomonadaceae_uncultured (order Nitrosomonadales) with relative abundances of 2.83–7.17%. For VC, the dominant bacterial genus was BIrii41_norank (except at 45 d), which accounted for 2.11–7.96% of the total reads. The dominant fungal class was Sordariomycetes in AC (relative abundances 39.2–80.6%) and VC (relative abundances 42.1–69.5%). The abundances of microbial taxa and therefore the bacterial and fungal community structures differed between VC and AC. The quality of the green waste compost product was higher with VC than with AC. These results will also help to achieve further composting technology breakthroughs in reducing the composting time and improving compost quality.

“…Physico-chemical properties of soil such as pH, electrical conductivity (EC e , in saturated soil extracts), cation exchanged capacity (CEC), exchangeable sodium percentage (ESP) and sodium adsorption ratio (SAR) were analysed as described elsewhere [18]. In this study, the phosphate-solubilizing Bacillus megaterium (ATCC 14581), nitrogen-fixing Azotobacter chroococcum (MTCC 446) [19], indole acetic acid (IAA) producing Pseudomonas monteilii (HQ995498) [20] and AMF Rhizophagus intraradices were used as bioinoculants for cultivation and growth promotion C. zizanioides under salt affected soil. The pure cultures of microorganisms used in this study were obtained from Microbial Technology Division, CSIR-CIMAP, Lucknow, India.…”

“…The increased plant growth in VC amended treatment (salt-affected soil amended with 5 t ha -1 VC) in comparison to control treatment CS (only salt-affected soil) depicted stress mitigation and plant growth promotion ability of vermicompost in salt-affected area. Vermicompost contains higher amount of essential nutrients (N, P and K) required for plant growth and soil conditioning [20,30]. In treatment VC, vermicompost was used in double amount with the view to the make a comparative analysis of plant growth in presence of vermicompost (5 t ha -1) , and bioinoculants ?…”

“…Pseudomonas monteilii produced indole 3-acetic acid required for root proliferation whereas B. megaterium is an efficient phosphate solubilizer. The nitrogen fixing A. chroococcum was used to increase the nitrogen content of soil [19,20]. Likewise, AM fungi (R. intraradices) confer several benefits to plants including increased uptake of water, and acquisition of phosphorus and other immobile nutrients [20].…”

Restoration of salt-affected soil through cultivation Chrysopogon zizanioides is a promising approach. The two way benefit of such an approach is that reclamation of salt-affected soil concomitant to improve plant growth and increased yield of essential oil produced in the plants roots. Earlier studies showed physiological changes and reduced growth of C. zizanioides under salinity. In the present study, plant growth promoting microorganisms viz. Pseudomonas monteilii, Bacillus megaterium, Azotobacter chroococcum and Rhizophagus intraradices were used as bio-inoculants for cultivation of C. zizanioides under saltaffected soil. Bio-inoculants in combination with vermicompost significantly increased the growth and productivity of C. zizanioides under salt-affected soil, and simultaneously improved soil health. When compared to control, the soil physico-chemical and biological properties of bio-inoculants treated plants was significantly improved. The reclamation of salt-affected soil was evident by the significant decrease in the level of soil pH (11.0%), electrical conductivity (23.5%), sodium adsorption ratio (15.3%), and exchangeable sodium percent (12.4%) of bio-inoculants treated plants. The improvement of soil cation exchange capacity indicated the decrease in soil salinity. Whereas increase in the microbial count (four-fold), AMF spores (447 spores), dehydrogenase (six-fold), acid (twofold) and alkaline phosphatase (five-fold) activities in rhizosphere soil of bio-inoculant treated plants indicated the improved biological properties. A positive correlation of plant biomass production to soil organic carbon, total Kjeldahl nitrogen, available phosphorus and cation exchange capacity depicted improved nutrients content in rhizosphere soil of bio-inoculant treated plants. The findings of this study suggest that P. monteilii and R. intraradices with vermicompost can be effectively used as bio-inoculants for encouragement of phytoremediation in salt-affected soil.

Vermicomposting is a process where worms are used to transform organic waste products into fertilizers for agricultural use and as soil amendments to improve soil health. Vermicompost is used in agriculture as both an organic fertilizer and a soil amendment due to its large biological component and abundant nutrient concentrations, in particular nitrogen (N). Vermicomposts promote soil microbial biodiversity by inoculating the soil with a wide array of beneficial microbes, which can enhance plant growth by the production of plant growth-regulating hormones and enzymes while also controlling plant pathogens and nematodes, all of which can minimize crop yield losses. Current and historical studies have evaluated many vermicompost types for their ability to increase crop growth, development, and fruit quality across a wide range of field and greenhouse crops. Many of these studies conclude that crop response to vermicompost can meet or exceed crop response to conventional rates of synthetic fertilizers. Vermicompost use has therefore been increasingly considered in conventional and organic agricultural systems as an alternative to synthetic fertilizers to decrease N losses. However, it is difficult to determine the short and long-term effects to soil N cycling with increased vermicompost use in agriculture. Here, we summarize the current state of knowledge regarding the influence of vermicompost on N dynamics in laboratory and agricultural settings. In particular, the physical, chemical and biological means of N cycle alteration following vermicompost use is examined, with emphasis on the ability of vermicomposts to influence N leaching. We find conflicting results regarding the influence of vermicomposts on soil N dynamics, in particular the influence of vermicompost on soil N flux over short and long time scales. We find evidence for both soil N retention and leaching with vermicompost use, largely contingent on rate of application and vermicompost type.The differences in chemical, biological and physical properties between vermicompost types along with a wide range of recommended rates of application may pose problems for large-scale adaptation of vermicompost use in commercial agriculture. It is important to determine a proper "goldilocks" rate of vermicompost amendment for crop systems that supports high crop yield while minimizing N leaching. We conclude that much research still needs to be performed in laboratory and field settings to study N dynamics with vermicomposts.
