“…One alternative disease management strategy involves the use of soil organic amendments such as compost and biochar (Smith and Collins 2007;Sohi et al 2010;Ruano-Rosa and Mercado-Blanco 2015). Composts are known to improve the soil health and to suppress various soil-borne diseases caused by fungal pathogens belonging to diverse genera such as Fusarium, Pythium, Rhizoctonia and Phytophthora (Larkin 2015;Mehta et al 2014). The suppressiveness of compost may be attributed to a beneficial microbial community, an improvement in plant growth and vigour, an increased nutrient availability, the induction of systemic resistance or to the stronger fungistatic abilities of the compost amendments (Bonanomi et al 2007).…”

Background and aims Biochars are recognised for their ability to improve soil functions and to stimulate plant defense mechanisms. We evaluated the response of Fusarium oxysporum f. sp. lycopersici chlamydospores to tomato plants grown in biochar and compost amended soil to get a deeper insight into the tomato-Fusarium pathosystem. Methods Wood chips and green waste biochar in combination with compost ('WCB comp and GWB comp ' respectively) were studied for their ability to suppress the Fusarium chlamydospores infectivity. Plant growth parameters and in vitro effects on chlamydospores were determined. Results The 'GWB comp ' soil amendment stimulated plants growth and gaseous exchange rates and had a suppressive effect on the chlamydospore infectivity in comparison with the 'WCB comp ' treatment and the treatment containing compost only. The germination rate of chlamydospores was unaffected by the source of root exudates, whereas the mycelial growth was significantly higher in root exudates from chlamydospore inoculated plants grown in 'WCB comp ' amended soil unlike to 'GWB comp ' amended soil. Conclusion Overall, our findings indicate that both biochars had a variable effect on chlamydospores. We conclude that soil amendment with garden waste biochar and compost exhibit a great potential in suppressing Fusarium chlamydospore infectivity and alleviating pathogen-induced physiological stress in tomato plants.

“…The heap of organic waste undergoes microbial degradation that converts organic waste into compost. During composting, organic material passes through the thermophilic phase (45-65°C) that kills numerous pathogenic microorganisms due to release of CO 2 , water and heat (Lung et al 2001;Alidadi et al 2005;Mehta et al 2014;Soobhany et al 2017). Several physio-chemical parameters affect the composting process such as temperature, moisture, pH, particle size, aeration and electrical conductivity (Li et al 2013;Juárez et al 2015;Onwosi et al 2017).…”

Sustainable food production is one of the major challenges of the twenty-first century in the era of global environmental problems such as climate change, increasing population and natural resource degradation including soil degradation and biodiversity loss. Climate change is among the greatest threats to agricultural systems. Green Revolution though multiplied agricultural production several folds but at the huge environmental cost including climate change. It jeopardized the ecological integrity of agroecosystems by intensive use of fossil fuels, natural resources, agrochemicals and machinery. Moreover, it threatened the age-old traditional agricultural practices. Agriculture is one of the largest sectors that sustain livelihood to maximum number of people and contribute to climate change. Therefore, a climate-smart approach to sustainable food production is the need of hour. Traditional agriculture is getting increased attention worldwide in context of sustainable food production in changing climate. The present article advocates traditional agriculture as a climate-smart approach for the sustainable food production and also deliberates the correlation between climate change and agriculture.

“…Composting is one of the possible treatments where a biotransformation of solid organic matter into a matured and stabilized substrate, due to microbial action under aerobic conditions, takes place. Usually, three different phases can be recognized during the composting process: (1) mesophilic phase (up to 40 C), which usually lasts for a couple of days; (2) thermophilic (over 40 C), which can last from a few days to several days; and (3) mesophilic curing or maturation phase (up to 40 C), which can last for several months (Mehta et al, 2014).…”

Fungal communities in pressmud composting harbour beneficial and detrimental fungi for human welfare

et al. 2016

Pressmud is a substrate derived from sugarcane juice filtrate, and around 26-40 kg of this residue are produced per ton of sugarcane. It is mainly used as fertilizer in crops, and its application in the field is often made without any prior treatment, but, in this research, it was studied for the risk this practice poses for human health. This research was stimulated by previous results indicating the presence of opportunistic pathogens in residues used in various composting systems and the extensive use of fresh pressmud in agriculture. Here, It was assessed the fungal diversity present in both fresh and composting pressmud using 454 pyrosequencing. In addition, heat-tolerant fungi were isolated and surveyed for their enzymatic repertoire of biomass-degrading enzymes (cellulase, xylanase, laccase and polygalacturonase). A wide range of opportunistic pathogens was found among the most abundant taxa in the fresh pressmud, such as Lomentospora prolificans (43.13 %), Trichosporon sp. (10.07 %), Candida tropicalis (7.91 %), and Hormographiella aspergillata (8.19 %). This indicates that fresh pressmud might be a putative source of human pathogenic fungi, presenting a potential threat to human health if applied as fertilizer without any treatment. With regard to the heat-tolerant fungi found in this substrate, all the 110 isolates screened were able to produce at least one of the tested enzymes. The pressmud composting process not only effectively reduces the load of pathogenic fungi, but also creates an interesting environment for fungi able to produce thermostable hydrolytic and oxidative enzymes with biotechnological applications.
