Field weathering of spent mushroom substrate (SMS) produces soluble compost leachate that percolates into underlying soils and may adversely impact groundwater. Laboratory experiments were conducted to investigate movement and retention of SMS leachate solutes in subsurface soil columns. Spent mushroom substrate leachate with high concentrations of dissolved organic matter (DOM) and inorganic s...

The potential of Pleurotus ostreatus spent mushroom compost (PSMC) as a green biosorbent for nickel (II) biosorption was investigated in this study. A novel approach of using the half-saturation concentration of biosorbent to rapidly determine the uptake, kinetics and mechanism of biosorption was employed together with cost per unit uptake analysis to determine the potential of this biosorbent....

Spent mushroom compost (SMC) of Pleurotus pulmonarius (an edible fungus) was used as soil conditioner for the improvement of growth of four common Nigerian vegetables (Abelmoschus esculentus, Lycopersicum esculentum, Capsicum annum and Capsicum chinense). The results of these investigations showed that the vegetables responded well to the SMC treatment. Each of them attained its best growth and...

abstract in composting process for the white button mushroom, in addition to chemical reactions of complex compounds present in straw, which provide simple compounds for the mushroom, thermophilic microorganisms, having accumulated n2 and inorganic matter during the composting processes, offer the microbial biomass as a secondary nutritional source to be consumed by the fungus agaricus bisporus...

Spent mushroom compost (SMC) is a by-product of the mushroom industry that is used as an agricultural fertilizer. In Europe, SMC storage and use are governed by EU Nitrates Directive 91/676/EEC to protect waterways against pollution by nitrates. A health and safety risk was identified during the removal of stored SMC for land application, as the stored SMC released high levels of toxic H2S gas ...

The objective of this study was to determine the effect of spent mushroom compost (SMC) meal on the growth performance and meat characteristics of geese. The SMC extracts contained 2.49±0.62 mg gallic acid equivalent/g dry weight (DW) and 1.08±0.15 mg quercetin equivalent/g DW of the total phenolic and flavonoid contents. A total of 120 White Roman geese, aged five weeks, were randomly distribu...
