“…5). The emergence of PLFA profiles associated with G + and G − bacterial communities has been observed in compost and after the introduction of SMC to soil (Hřebečková et al, 2020;Zheng et al, 2020;Suwannarach et al, 2022). This suggests that the growth environment in SMC can support a bacteria-centric structure with the potential for enhancing disease suppression against plant pathogens.…”

“…When mushrooms are harvested in the eld, a signi cant amount of mycelium and organic sources, known as spent mushroom substrate, is generated directly in the soil. This residue has been proposed as a sustainable substitute for synthetic fertilizers, given its soil conditioning, nutrient release, plant growth promotion, and soil microbiome-enhancing properties (Hřebečková et al 2020;Qin et al 2022). Successful mushroom-plant management practices such as Volvariela-coconuts (Mohapatra and Niranjan 2014), Pleurotus-fava beans (Hamed et al 2021), and Morchella-peach (Song et al 2021) illustrate the potential of such practices.…”

“…is the most critical nutrient for plant growth and development since it plays a vital role(Louarn et al 2021). SMS is not a good supplier of N and may even provide greater N immobilization rates in the soil than mineralization rates during the crop year(Hřebečková et al 2020). To ensure high yield e ciency,Aluoch et al (2022) emphasize that maize production requires the combined application of manure (organic waste) and nitrogen fertilizers, indicating the crop's high demand for N.…”

The reuse of sun mushroom post-harvest areas (SMS) presents an innovative alternative for smallholders seeking to move away from conventional maize cropping systems and reduce their reliance on synthetic fertilizers. This study evaluated the growth of two successive maize crops in post-harvest areas while assessing drivers of yields and soil/leaf macronutrient composition. Four management practices were carried out: SMS, without the application of synthetic fertilization; SMS + S, with the application of synthetic fertilization recommended at sowing; SMS + S + TD, with the application of synthetic fertilization at sowing and topdressing; and Control, a common area with the application of synthetic fertilization. Agronomic aspects and macronutrients soil and leaf contents were evaluated in two successive maize crops in post-harvest areas. Different management practices adopted in the sun mushroom post-harvest areas did not significantly differ between yields in the first crop. SMS provided an increase in P, Ca, and Mg in the soil for the first crop and an increase in P and Ca for the second crop, indicating mineralization of the SMS. Nevertheless, the macronutrient content was reduced in the successive crops without sowing and topdressing fertilization (SMS + S + TD), indicating a dependence on synthetic fertilizers in intensified systems. Despite a nutritional limitation of the Ca: Mg/K ratio, SMS results in a maize yield comparable to the control in the first crop. The application of N in these areas was crucial for the second crop.

“…In the most efficient oyster mushroom production systems, the ratio of spent mushroom substrate to fresh mushrooms is roughly 5:1 by dry mass ( 56 ). The estimated 2017 global yield of Pleurotus mushrooms was 4.7 million metric tons, meaning that a minimum of five times that amount of spent substrate required management ( 57 ). Thus, utilizing spent mushroom substrate to feed insects could present a win-win opportunity for farmers.…”

Suitability of maize crop residue fermented by Pleurotus ostreatus as feed for edible crickets: growth performance, micronutrient content, and iron bioavailability

Small-scale farming of edible insects could help combat public health challenges such as protein energy malnutrition and anemia, but reliable low-cost feeds for insects are needed. In resource-limited contexts, where grains such as maize are prohibitively costly for use as insect feed, the feasibility of insect farming may depend on finding alternatives. Here, we explore the potential to modify plentiful maize crop residue with edible mushroom mycelium to generate a low-cost feed adjunct for the farmed two-spotted cricket, Gryllus bimaculatus. Mushroom farming, like insect agriculture, is versatile; it can yield nutritious food while increasing system circularity by utilizing lignocellulosic residues from row crops as inputs. Pleurotus ostreatus, is an edible basidiomycete capable of being cultivated on corn stover (Zea mays). Mushroom harvest results in abundant “spent” substrate, which we investigated as a candidate feed ingredient. We created six cricket feeds containing fermented Pleurotus substrate plus an unfermented control, measuring cricket mass, mortality, and maturation weekly to evaluate cricket growth performance impacts of both fungal fermentation duration and mushroom formation. Pasteurized corn stover was inoculated with P. ostreatus mycelium and fermented for 0, 2, 3, 4, or 8 weeks. Some 4 and 8-week substrates were induced to produce mushrooms through manipulations of temperature, humidity, and light conditions. Dried fermented stover (40%) was added to a 1:1 corn/soy grain mix and fed to crickets ad libitum for 44 days. The unfermented control group showed higher survivorship compared to several fermented diets. Control group mass yield was higher for 2 out of 6 fermented diets. Little variation in cricket iron content was observed via ICP-spectrometry across feeds, averaging 2.46 mg/100 g. To determine bioavailability, we conducted in vitro Caco-2 human colon epithelial cell absorption assays, showing that iron in crickets fed fruiting-induced substrates was more bioavailable than in unfruited groups. Despite more bioavailable iron in crickets reared on post-fruiting substrates, we conclude that Pleurotus-fermented stover is an unsuitable feed ingredient for G. bimaculatus due to high mortality, variability in growth responses within treatments, and low mass yield.
