“…Nitrogen transition: According to Mahanta et al (2012), nitrogen concentration of compost increases after microbial inoculation, but as soon as compost gains the maturity, nitrogen transition to N-NH 4 + and N-NO 3 becomes constant, which was clearly evident in our study. Even after inoculation, N-NH 4 + and N-NO 3 remained constant, indicating a no more dynamic N transformation during composting.…”

“…Microbial inoculation with nitrogen fixing bacteria into compost increased contents of N and P (Kumar and Singh 2001). Mahanta et al (2012) also reported that microbial enriched compost showed significant increases in N content. Most of the organic manures are very low in nutrient contents, which are not sufficient to meet the nutritional requirement of the crops, especially when inorganic fertilizers are not applied (Manna et al, 2001).…”

Present study deals with the enrichment of kitchen waste compost (KWC) with Trichoderma harzianum and to analyze its effect on physico-chemical and microbial parameters with respect to different days. The result found that there were minor increments in vital nutrient which required for plant nutrition and healthy development. Statistically, it had also proven that after inoculation or enrichment of KWC, around 14th day it gave better results and could be utilized in organic farming to secure better yield and nutritious response of crops.

“…The soil microbial biomass has extremely important functions in soil ecosystems, such as converting organic matter into nutrients that could be absorbed and utilized by plants, promoting organic carbon metabolism, and transferring nutrients in plants [38][39][40] . The soil microbial biomass carbon (MBC) and nitrogen (MBN) could be increased to various degrees by applications of B. mucilaginosus and A. niger, as shown in Table 4.…”

With the improvement of living standards, people pay more and more attention to the quality and safety of rice. Microbial agents are favored by the public because they can activate the nutrient supply in the soil, and reduce the residue and application amount of chemical fertilizers and pesticides. Based on the conventional fertilization in the field, Bacillus mucilaginosus and Aspergillus niger were applied, Bacillus mucilaginosus was inoculated at four levels in the paddy soil in the cold region of Heilongjiang Province of China. The effects of different proportions of Bacillus mucilaginosus and Aspergillus niger on the number of soil microorganisms, enzyme activity, microbial biomass, soil biochemical intensity, soil nutrient content, plant nutrient content and yield were studied, and the effects on the plant nutrient content of rice and the nutrient dynamics were discussed. The results showed that a 2.62%-21.20% higher yield of rice obtained from co-application treatments compared with that of the control-blank treatment. Furthermore, the highest yield obtained (10736±65 kg/hm 2) suggested that the optimized values for the two bacteria applied were 120×10 11 CFU/hm 2 for Bacillus mucilaginosus and 15×10 11 CFU/hm 2 for Aspergillus niger. Bacillus mucilaginosus can decompose minerals in soil, dissolve potassium and silicon, decompose apatite and release phosphorus into soil. Aspergillus niger can transform the phosphate which cannot be absorbed by plants into soluble phosphate which can be directly absorbed by plants by producing non-volatile acids. In particular, Bacillus mucilaginosus and Aspergillus niger have synergistic effect, and their combined application effect is greater than that of two bacteria alone. Co-application promoted the release of soil soluble silicon, and then increased the silicon content of plants. At the same time, soil microorganism, microbial biomass, enzyme activity and biochemical activity all increased significantly. This study provides an effective way to reduce the amount of chemical fertilizer applied in rice production in cold regions of China.

“…Due to richness of nutrients and availability of beneficial microorganisms in the vermicompost, it has tremendous potential in enhancing soil fertility, crop yield and plant protection against significant pest and pathogen attack. Likewise, the cellulose-degrading microorganisms (CDMs) are also known as an efficient driver in biodegradation processes like enzyme digestion, nitrogen excrement and transport of immobilized nutrients in soil (Mahanta et al 2012b). The microorganisms are known to produce enzymes like cellulase, endoglucanase, and cellobiohydrolase that work synergically to degrade cellulose.…”

“…Decomposition of organic residues might assist in nutrient release and thereby make them available for the use of living organisms (Mahanta et al 2012b). Compost recovery percentage was maximum in the treatment applied with earthworm and CDM with poly lining in the pit (69.1%) followed by earthworm and CDM without poly lining (67.5%) over untreated control (53.2%).…”

Purpose A suitable strategy for bioconversion of agricultural waste into quality organic manure and its efficient utilization was assessed in the hilly ecosystem of Northeast India. Methods Pits were dug in terrace lands and filled with chopped plant biomass (rice straw, maize stover and mixed weed biomass) with alternate layers of cow dung at 3:2 ratio. The treatment consisting of control (plant biomass + cow dung), plant biomass + cow dung + earthworm (Eisenia fetida) (with or without poly lining in the pit) and plant biomass + cow dung + earthworm + cellulose-degrading microorganism (Pseudomonas sp.) (with or without poly lining in the pit) was used for the bioconversion process. Results Combined inoculation of E. fetida and Pseudomonas sp. with poly lining in the pit significantly enhanced compost recovery (29.8%), cellulase activity (55.2%) and the C:N ratio (1.9%) as compared to control. Significant achievement in yield components and nutrient status in soil was observed after combined application of compost with 50% recommended dose of fertilizer. Conclusion The current investigation established dual inoculation effect of E. fetida and Pseudomonas sp. with poly lining in the pit as a suitable technology for faster decomposition and effective bioconversion of agricultural waste into quality organic manure. A treatment imposed with such organic manure will be supportive in enhancing crop production as well as improving soil health.
