Disease suppressive soils vary in resilience to stress

Disease-Suppressive Soils—Beyond Food Production: a Critical Review

“…According to Oerke ( 2006 ), plant diseases could threaten up to 82% of attainable yield in cotton and more than 50% for most of the major crops. These yield losses due to plant diseases are a huge concern, especially in resource-poor countries (Chakraborty and Newton 2011 ; Döring et al 2020 ). Several authors highlight the “fertilization effect” of increasing atmospheric CO 2 that might help in increasing food production (Ainsworth and Long 2005 ).…”

“…While we are worried about the impacts of rising temperature stress on crop production (Dawson et al 2016 ), there is complete lack of sufficient quantitative evidences on use of DSS in climate change conditions (Pautasso et al 2012 ). The possible effects of climate change on plant diseases include acceleration of pathogen evolution, shorter incubation periods, early attack of the disease, higher susceptibility of the host plants to soil-borne pathogens, and geographical expansion of plant diseases (Döring et al 2020 ). While few soil-borne pathogens, such as Pythium cinnamon , showed a null response to climate change (Thompson et al 2014 ), others have demonstrated a reduction of disease suppressiveness against Rhizoctonia solani after heat treatment of the soil (50 °C) (der Voort et al 2016).…”

The combined heat and drought stress could reduce the disease suppressiveness of the test soils (Döring et al 2020 ), although the change varies in different soils due to differences in soil microbial community. Soils from dry and arid areas or located in high altitude with summer temperatures, and that has been already experienced heat stress are more vulnerable to decrease its disease suppressiveness due to predicted temperature rise in future (Döring et al 2020 ).…”

Such experiments could also show recovery of the soil microbial communities after the removal of temperature stress (Griffiths and Philippot 2013 ).…”

Climate change‐triggered land degradation and planetary health: A review

“…Changes in temperature, moisture, and rainfall not only affect plant physiology but also increase the prevalence of plant pathogens and pests that also can potentially reduce crop productivity (Avila et al, 2019; Curlevski et al, 2014; Döring et al, 2020; Moretti et al, 2019) and lead to livelihood, food, and nutritional insecurity. Biogeochemical changes in soil and water in coastal agroecosystems due to climate change may cause nutrient export (dissolved inorganic N, soluble reactive P) downstream from these coastal farmlands, leading to nutrient pollution issues in watersheds (Weissman & Tully, 2020) and making agriculture and livelihoods vulnerable.…”
