“…The fresh biomass of lettuces was significantly stimulated with the SMS applications, and a similar result was also reported by Zied et al (2021). The SMS was enriched in various macro-and micronutrients and could improve soil porosity and enzyme activities, stimulating plant growth (Roy et al, 2015).…”

Spent mushroom substrates can be utilized as organic fertilizer in agricultural production but may pose a health risk. Nitrification inhibitors dicyandiamide and 3,4-dimethylpyrazole phosphate have been used to enhance fertilizer nitrogen utilization efficiency. However, the changes of soil abiotic properties, microbial activities, nitrogen cycling and human-disease genes, and their comprehensive relationships after the spent mushroom substrate and nitrification inhibitor applications were still unknown. In this study, the spent mushroom substrate and nitrification inhibitor were applied into the agricultural soils at the rates of 2.5% (w/w) and 1.0% of nitrogen content in the spent mushroom substrate, respectively, and then lettuce was planted. Compared with the control, spent mushroom substrate application significantly increased the lettuce biomass, soil enzyme activities and chitinase, protease, nitric-oxide reductase, nitrogenase, and urease gene abundances. However, the antibiotic resistance and human-disease gene abundances were also significantly enhanced following the spent mushroom substrate application.Relative to spent mushroom substrate alone, the dicyandiamide application significantly decreased the soil pH and human-disease gene abundances, although extra dicyandiamide and 3,4-dimethylpyrazole phosphate enhanced 61.4% and 45.0% of dry biomass of aboveground lettuce. The human-disease gene abundances were positively correlated with soil pH but were negatively correlated with the Acidobacteria and Streptomyces ratios in soils. Spent mushroom substrate application could generate double-edged sword effects, and the health risk should be considered in the spent mushroom substrate applications. Extra dicyandiamide application could further promote crop growth while decrease the human-disease risk from the spent mushroom substrate.

“…Considering the best yield obtained (rice straw), it was observed that the nutrient with the highest pre-and post-cultivation values was K, which is evidence of its importance in mushroom nutrition. K sources are commonly used in supplementation, both in spawning and in substrate formulation after wetting [34][35][36].…”

Organic agricultural waste is successfully used in the production of mushrooms as it promotes the reuse of resources and increases food production. For the formulation of the substrate for Pleurotus spp. production, the availability of nutrients must be rigorously analyzed to assess whether supplementation is necessary. The aim of this paper was to evaluate the agronomic behavior of Pleurotus ostreatus var. Florida when grown on different straws and to analyze nutrient dynamics at the beginning and end of cultivation. Straws of rice, wheat and brachiaria were used as substrates without any supplementation. The yields, biological efficiency, number and weights of mushrooms were evaluated in two crop cycles. Rice straw provided a higher yield, better biological efficiency and a greater number of mushrooms in both cultures. Wheat straw showed intermediate results for the same variables. None of the substrates showed a significant difference for mushroom weight. In the first crop, only Mg and the number of mushrooms exhibited a positive correlation; in the second crop, only K and the yield of the 1st flush showed a positive correlation. With this study, it was possible to demonstrate that agricultural residues with higher levels of K increase P. ostreatus yield, and that Mg management affects the number of mushrooms for harvesting. The results will be a useful guide for efficient and sustainable mineral supplementation of the substrate.

Spent mushroom substrate (SMS) is the by-products of mushroom production, which is mainly composed of disintegrated lignocellulosic biomass, mushroom mycelia and some minerals. The huge output and the lack of effective utilization methods make SMS becoming a serious environmental problem. In order to improve the application of SMS and SMS derived biochar (SBC), composted SMS (CSMS), SBC, combined plant growth-promoting rhizobacteria (PGPR, Bacillus subtilis BUABN-01 and Arthrobacter pascens BUAYN-122) and SBC immobilized PGPR (BCP) were applied in the lettuce seedling. Seven substrate treatments were used, including (1) CK, commercial control; (2) T1, CSMS based blank control; (3) T2, T1 with combined PGPR (9:1, v/v); (4) T3, T1 with SBC (19:1, v/v); (5) T4, T1 with SBC (9:1, v/v); (6) T5, T1 with BCP (19:1, v/v); (7) T6, T1 with BCP (9:1, v/v). The physicochemical properties of substrate, agronomic and physicochemical properties of lettuce and rhizospheric bacterial and fungal communities were investigated. The addition of SBC and BCP significantly (p < 0.05) improved the total nitrogen and available potassium content. The 5% (v/v) BCP addiction treatment (T5) represented the highest fresh weight of aboveground and underground, leave number, chlorophyll content and leaf anthocyanin content, and the lowest root malondialdehyde content. Moreover, high throughput sequencing revealed that the biochar immobilization enhanced the adaptability of PGPR. The addition of PGPR, SBC and BCP significantly enriched the unique bacterial biomarkers. The co-occurrence network analysis revealed that 5% BCP greatly increased the network complexity of rhizospheric microorganisms and improved the correlations of the two PGPR with other microorganisms. Furthermore, microbial functional prediction indicated that BCP enhanced the nutrient transport of rhizospheric microorganisms. This study showed the BCP can increase the agronomic properties of lettuce and improve the rhizospheric microbial community.
