“…Manure compost study by Abbey and Appah [18], 25% (w/w) of the seafood waste compost, municipal solid waste compost, and the vermicompost were individually incorporated into 400 g of Promix-BX soilless potting mix (Premier Horticulture Inc., Quakertown, PA, USA) purchased from Halifax Seeds, Nova Scotia, using 25.4 cm diameter plastic pots. The control treatment was a 400 g of the Promix-BX potting mix alone without the addition of any amendment.…”

Growing medium amino acids and mineral nutrients stimulate rhizosphere activities and plant growth. A greenhouse experiment was performed to compare amino acid and mineral nutrient profiles of seafood waste compost (SFWC) and municipal solid waste compost (MSWC) and vermicompost (VC). Their efficacies were also tested on onion (Allium cepa L. "Sweet Utah"). The control was Promix-BX6 alone. The MSWC, SFWC, and VC were composed of total of 36.4, 48.3, and 67.5 mg amino acids/100 g dry weight, respectively. Glutamic acid, aspartic acid, and glycine were the highest while methionine, histamine, and cysteine were the least in all the amendments. The VC had the highest Ca content but the least P and K contents. SFWC had the highest content of P and K and most of the determined micronutrients. The MSWC had significantly ( < 0.05) the highest N and leaf chlorophyll contents followed by the VC. The MSWC significantly ( < 0.05) increased anthocyanin content while the control recorded the least. The maximum quantum yield of photosystem II (Fv/Fm) and the potential photosynthetic capacity (Fv/Fo) were least in the VC treated plants. Dry matter was not affected by the type of amendment. Overall, plant growth was improved by the MSWC. Future research should investigate effect on secondary metabolites.

“…The balance between various nutrients is key to their availability for plant use. In a previous study, Abbey and Appah 13 found that application of manure compost at a rate of 50% or more retarded plant growth due to increased nutrient toxicity. Another study indicated that excessive uptake of plant nutrients such as phosphorus from vermicompost antagonized iron uptake and its assimilation leading to reduced plant growth.…”

Vermicompost is a nutrient-rich amendment commonly used to restore soil health such as restoration of trace element contamination of growing media. A pot study was carried out to determine vermin compost and copper (Cu) interaction on little finger carrot (Daucus carota cv. Nantes) seedlings emergence and plant growth. The treatments were varying rates of Cu (i.e., 0, 100, 200 and 300 mg Cu l-1) and vermicompost (i.e., 0, 25, 50 and 75% w/w).At two weeks after sowing, the emergence rate of carrot seedlings in pots with no vermicompost (i.e., control) were 0.22, 0.25, and 0.32 folds higher than those that received the 25%, 50% and 75% vermicompost, respectively. Vermicompost, Cu and their interaction had significant (p<0.05) effects on leaf chlorophyll and anthocyanin contents. The 50% vermicompost combined with the 100 mg Cu l-1 resulted in greater leaf greenness and anthocyanin content. Plant height and number of leaves were significantly (p<0.05)increased by 0.07 and 0.16 folds following the application of the 25% and 50% vermin compost respectively, compared to the control. The 50% vermicompost had a strongly positive impact on the carrot shoot compared to the root. This preliminary study on little finger carrot cv. Nantes seedlings will require further detailed studies to explain vermicompost mitigation of Cu stress on carrot plants and productivity.

“…In sustainable agricultural systems, natural amendments such as vermicast, a pure worm excreta, is widely used to improve the quality and health of growing medium and to meet the nutritional needs of plants [7]. A greenhouse pot experiment revealed that application of vermicast alone (100%) or 75% vermicast with added Mycorrhizal fungi were toxic to plants due to high chemical nutrients concentration compared to the addition of 25% or 50% vermicast [8]. Vermicast is rich in beneficial microorganisms, essential nutrients, humic and non-humic substances and growth-promoting hormones with desirable physical properties [9][10][11].…”

Mineralization and nutrient release pattern of vermicast-sawdust mixed media with or without addition of Trichoderma viride

A combination of vermicast and sawdust mixed medium is commonly used in horticulture, but the added benefit of microbial inoculation and mechanism of nutrient availability are unknown. This study was done to determine nutrient mineralization and nutrient release patterns of different combinations or a mix of vermicast-sawdust growing media amended with or without Trichoderma viride (105 spores/g). The mixed-media treatments were (1) 80% vermicast+20% sawdust; (2) 60% vermicast+40% sawdust; (3) 40% vermicast+60% sawdust; (4) 20% vermicast+80% sawdust; and (5) sawdust alone (control). Total dissolved solids, electric conductivity and salinity increased with each sampling time following submergence in deionized. Nutrients released from media without T. viride were significantly higher than the corresponding media with added T. viride. Overall, the starting total nitrogen of the different media did not change during the incubation period, but nitrate-nitrogen was reduced to a negligible amount by the end of day 30 of incubation. A repeated measures analysis showed a significant effect of Time*T. viride*Treatment on total dissolved solids. Redundancy analysis demonstrated a positive and strong association between media composed of ≥40% vermicast and ≤60% sawdust with or without T. viride and mineral nutrients released, electrical conductivity, total dissolved solids and salinity. These findings suggest that fast-growing plants may benefit from 40% to 60% vermicast added to 40% to 60% sawdust without T. viride while slow-growing plants can benefit from the same mixed medium combined with the addition of T. viride. Further investigation is underway to assess microbial dynamics in the mixed media and their influence on plant growth.
