“…According to the Intergovernmental Panel on Climate Change [154], if current greenhouse gas emissions continue, there will be a projected increase of 2.1-3.5 • C of global temperature by the years 2081-2100. C plays a crucial role in the complex interaction that influences soil fertility and climate patterns [155]. C sequestration is a crucial process that involves capturing and storing atmospheric CO 2 , which helps in reducing its concentration in the atmosphere and thus mitigates the negative impacts of climate change.…”

“…C sequestration is a crucial process that involves capturing and storing atmospheric CO 2 , which helps in reducing its concentration in the atmosphere and thus mitigates the negative impacts of climate change. The C cycle involves the storage of approximately 50% of the substances produced from photosynthesis in biomass and SOM, while the remaining portion is released into the atmosphere as CO 2 through the plant or microbial respiration and SOM decomposition [155]. Soil microorganisms have a significant impact on the C budgets of ecosystems.…”

“…Pesticides play an important role in preserving agricultural produce quality by controlling plant pathogens. Their use, however, can have an impact on the soil microbial community and alter its biochemical activities, which results in changes in soil enzyme functionalities [155]. In one study, the effects of 20 commercial pesticides on BG, CBH, and BX in 3 distinct south Australian agricultural soils were assessed.…”

The extracellular enzymes secreted by soil microorganisms play a pivotal role in the decomposition of organic matter and the global cycles of carbon (C), phosphorus (P), and nitrogen (N), also serving as indicators of soil health and fertility. Current research is extensively analyzing these microbial populations and enzyme activities in diverse soil ecosystems and climatic regions, such as forests, grasslands, tropics, arctic regions and deserts. Climate change, global warming, and intensive agriculture are altering soil enzyme activities. Yet, few reviews have thoroughly explored the key enzymes required for soil fertility and the effects of abiotic factors on their functionality. A comprehensive review is thus essential to better understand the role of soil microbial enzymes in C, P, and N cycles, and their response to climate changes, soil ecosystems, organic farming, and fertilization. Studies indicate that the soil temperature, moisture, water content, pH, substrate availability, and average annual temperature and precipitation significantly impact enzyme activities. Additionally, climate change has shown ambiguous effects on these activities, causing both reductions and enhancements in enzyme catalytic functions.

“…carbon and nitrogen cycling). [7][8][9] As an alternative, pesticides of biological origin, such as natural products, are gaining attention from the general public and the pesticide market due to their perceived low risk and environmentally safe nature. 10 Most natural products used as pesticides are secondary metabolites derived from two sources: (i) plants, which produce these compounds in response to microbial and pest infestations, referred to as botanicals, 11 and (ii) microorganisms, which produce these compounds as warfare agents to compete with other microorganisms for space and nutrients.…”

BACKGROUNDNatural products present an environmentally attractive alternative to synthetic pesticides which have been implicated in the off‐target effect. Currently, the assessment of pesticide toxicity on soil microorganisms relies on the OECD 216 N transformation assay (OECD stands for the Organisation Economic Co‐operation and Development, which is a key international standard‐setting organisation). We tested the hypotheses that (i) the OECD 216 assay fails to identify unacceptable effects of pesticides on soil microbiota compared to more advanced molecular and standardized tests, and (ii) the natural products tested (dihydrochalcone, isoflavone, aliphatic phenol, and spinosad) are less toxic to soil microbiota compared to a synthetic pesticide compound (3,5‐dichloraniline). We determined the following in three different soils: (i) ammonium (NH4+) and nitrate (NO3−) soil concentrations, as dictated by the OECD 216 test, and (ii) the abundance of phylogenetically (bacteria and fungi) and functionally distinct microbial groups [ammonia‐oxidizing archaea (AOA) and bacteria (AOB)] using quantitative polymerase chain reaction (q‐PCR).RESULTSAll pesticides tested exhibited limited persistence, with spinosad demonstrating the highest persistence. None of the pesticides tested showed clear dose‐dependent effects on NH4+ and NO3− levels and the observed effects were <25% of the control, suggesting no unacceptable impacts on soil microorganisms. In contrast, q‐PCR measurements revealed (i) distinct negative effects on the abundance of total bacteria and fungi, which were though limited to one of the studied soils, and (ii) a significant reduction in the abundance of both AOA and AOB across soils. This reduction was attributed to both natural products and 3,5‐dichloraniline.CONCLUSIONOur findings strongly advocate for a revision of the current regulatory framework regarding the toxicity of pesticides to soil microbiota, which should integrate advanced and well‐standardized tools. © 2024 The Authors.
