“…Consequently, fragments of composted SMC became increasingly encrusted with clay particles, which phenomenon rendered them partially inaccessible to further microbial attack. This was similarly noted by Ayuso et al (1996) and Pascual et al (1999), for sludge and compost, respectively.…”

“…Amendments of fresh SMC introduce a greater concentration of more easily degradable components than do amendments of composted material. Sequentially, these amendments would have stimulated and increased microbial activity, leading to the rapid production of soil-aggregate binding agents (Ayuso et al, 1996;Pascual et al, 1999). Conversely, during the composting process, biological transformation and mineralisation of these easily degradable fractions has already occurred and the remaining components are …”

In this paper, spent mushroom compost (SMC), a by-product of the mushroom industry, is proposed as a suitable organic amendment for soil structure restoration. A 4-month incubation pot trial was conducted in which fresh and composted SMC was amended at three different rates (50, 100 and 200 t ha À1 ) to a range of structurally degraded tillage soils (n ¼ 10). Soil OC content and aggregate stability as determined by the three disrupting tests of the Le Bissonnais method (fast-wetting, slow-wetting and mechanical breakdown) were investigated. Applications of 50, 100 and 200 t ha À1 fresh SMC increased the OC content by 2Á71 per cent, 2Á69 per cent and 2Á49 per cent respectively, while amendments of composted SMC increased the OC content by 3Á28 per cent, 2Á94 per cent and 2Á87 per cent for each application rate, respectively. The effect of SMC on aggregate stability was generally positive and statistically significant in most soils. However, in soils 3 and 4 an application rate of 200 t ha À1 SMC decreased the aggregate stability, on average, by 15 per cent, in comparison to the control, for the fast-wetting test. Aggregate stability was strongly controlled by the inherent OC content of the study soils; that is, the OC content prior to SMC addition. A positive correlation coefficient was also evident for the dithionite-extractable iron, most pronounced for slow-wetting and mechanical breakdown treatments (r ¼ 0Á844 and r ¼ 0Á817 respectively). It is clear from this research that SMC amendments have the capacity to improve soil structural stability.

“…Compost is of increasing importance as an amendment since it is able to improve the organic matter levels in marginal land and to sustain long-term fertility and productivity of soils (Ayuso et al, 1996;Esse et al, 2001;Castaldi et al, 2004).…”

Solid waste and air pollution are never ending environmental problems that can be partially solved by turning waste into useful bio-products. In this study, enzymatic solutions were developed by formulating enzymatic solutions from fish intestines and fruit peels. This aimed to help in biodegradation of organic solid wastes. Organic waste samples were treated with formulated enzymatic solutions for 7 days in aerated set-up for aerobic degradation. Biodegradability and odor of the waste samples were compared with commercial enzymatic solution. Determination of evolved carbon dioxide (CO 2 ) using gravimetric analysis (GA) was used to determine the percent biodegradability, Dt, of organic solid waste and odor-ranking method was used to determine the odor intensity of the organic waste samples. The result showed that the weight loss and percentage biodegradability of organic waste sample treated with formulated enzymatic solution is comparable with that of the commercial enzymatic solution. In terms of odor intensity, waste treated with the product, formulated enzymatic solution (FES) is also comparable to the waste treated with commercial enzymatic solution. Thus, implying that the developed FES is as efficient as that of the commercial enzymatic solution. These significant results will be helpful to future researchers in providing ways on improving the degradation of organic solid waste and mitigating the increasing glitches on our environment. Enzyme kinetics, physical and chemical properties studies of the solution were recommended for future researchers to accurately determine the effectiveness of the formulated enzymatic solution in the degradation of organic solid waste.
