“…The rapid degradation of organic waste during vermicomposting could also result in the loss of N due to leaching, among other things, which in turn could according to Bernal, et al [31] affect the E. fetida growth. In a related study, de Lima Rodrigues, et al [32], observed a decrease in earthworm density at the end of vermicomposting using cattle manure mixed with tannery sludge that had been amended with rock powder. In their study, the decline of earthworm was attributed to the decrease in the availability of the substrate in all the treatments at the end of the vermicomposting.…”

Vermicomposting using Eisenia fetida has been shown to improve phosphorus mineralization from rock phosphate (RP). There is, however, a lack of information on the potential of integrating microbial inoculants like phosphate-solubilizing bacteria (PSB) during vermicomposting as a way of improving vermidegradation, and the release of nutrients from igneous RP-amended composts. This study evaluated the potential of using Eisenia fetida and Pseudomonas fluorescence in enhancing the vermidegradation, and nutrient release in igneous RP- amended cow and pig manure-based vermicomposts at a C/N ratio of 30. Compost maturity, nutrient and phytotoxicity parameters were measured to determine vermicompost quality. Final vermicompost results showed that the pig manure treatments achieved greater maturity as indicated by lower C/N of 10.3, high humification index (HI) of 7.6%, and humification ratio (HR) of 12.89% in the treatment with E. fetida and P. fluorescence. The inclusion of E. fetida alone in cow manure treatment resulted in the highest Olsen P of 2600 mg/kg, followed by the pig manure treatment with E. fetida only (2246.15 mg/kg). In conclusion, both E. fetida and P. fluorescence are necessary in the vermicomposting of RP-enriched pig and cow manure for efficient vermi-degradation and nutrient release.

“…The seedling growth efficiency from the application of the different composts produced was analyzed using the Dickson quality index (DQI). For the DQI, 20 plants were randomly selected, and the following parameters were evaluated: seedling height, stem diameter, and shoot and root dry mass (Rodrigues et al, 2017;Meng, et al, 2019)…”

Composting Process in the Production of Lettuce Seedling Substrates: Effect of Covering and Turning Frequency

et al. 2020

The composting of waste from a broiler chicken production chain (BCPC) promotes the mitigation of environmental impacts and allows the commercialization of compost as an agricultural input. Both the characteristics and the potential for use of the final compost depends on the operational conditions during composting. The objective of this study was to evaluate the use of organic compounds generated from composting BCPC residues and the pruning debris of urban trees in the germination and initial growth of lettuce seedlings. Six organic substrates obtained under different coverage conditions (presence and absence) and number of turns (8, 12, and 16) were evaluated using the germination index (IG) and Dickson quality index (DQI) for the production of seedlings in trays and compared with a commercial substrate. Principal component analysis demonstrated that the IG is not related to the DQI. The compounds produced without coverage showed lower levels of electrical conductivity (p < 0.05) and potassium (p < 0.05) due to the leaching of soluble salts during composting. These substrates did not inhibit seed germination (IG ≥ 75%), but resulted in less robust seedlings, mainly in relation to the aerial portion. BCPC residues were viable for composting treatment and the DQI of the organic compounds (0.0125) used as substrates for the initial growth of lettuce seedlings were, on average, 14% higher than that obtained from the commercial substrate (0.090), indicating that the organic compounds were of better quality.

“…However, the current studies mostly selected the adequate species by statistical methods or focused on the ability of plants to accumulate heavy metals but lacked a systematic analysis of the field performance (such as height, diameter, and dry‐weight) of species. Currently, the comprehensive index, Dickson quality index (DQI) have been used to compare the performance of plants under different light conditions (Ranade & Gil, ); different fertilization conditions (Rodrigues et al, ); different N, P, and K ratios (Cuzzuol, Milanez, Gomes, Labate, & Canal, ); and different container characteristics (Chirino, Vilagrosa, Hernández, Matos, & Vallejo, ). It can also be used to predict the survival rate of plants according to their seedling morphology (Tsakaldimi, Ganatsas, & Jacobs, ).…”

Selection of suitable species as a key factor for vegetation restoration of degraded areas in an open‐pit manganese‐ore mine in Southern China using multivariate‐analysis methods

et al. 2019

Open‐pit mining results in large amounts of degraded lands that require ecological recovery. Adequate‐species selection for ecological recovery is of great importance. In this study, field investigations along the disturbance gradients (marginal area, restoration area, and control area) in a manganese ore deposit of Guangxi in Southern China were carried out. We screened the adequate species from two aspects. In the marginal area, the result of corrected Akaike information criterion revealed that Mn was the most important soil parameter affecting vegetation diversity. Cyclosorus parasiticus (L.) Farwell., Setaria viridis (L.) Beauv., Mimosa sepiaria Benth., and Bidens pilosa L. were selected for their abilities to adapt to high‐Mn‐content soils. In the restoration area and control area, we combined important values and field performance (Dickson quality index, DQI) of species to select adequate species. Miscanthus sinensis Anderss. and Arundinella hirta (Thunb.) Tanaka were selected using the similar DQI (p > 0.05) in both areas. In summary, C. parasiticus (L.) Farwell., S. viridis (L.) Beauv., M. sinensis Anderss., and A. hirta (Thunb.) Tanaka were selected as adequate species because of their high potential to adapt to these disturbed sites. Our results and methodology could have a demonstrating effect for restoration programmes in manganese ore mining areas of China.
