“…The processing of nutrients and carbon in the soil is often extremely complex and dynamic, and strongly influenced by characteristics of the soil, for example, organic matter composition and soil microbial community composition (Smukler et al, 2010;Mackay et al, 2016). The transformation of nutrients in the soil, which is largely driven by microbial processes (Sathya et al, 2016), can ultimately determine whether or not nutrients reach waterways (e.g. Gift et al, 2010).…”

“…Bacteria are important biological components that are essential in various functions in soils, such as the biogeochemical cycling of nutrients, improving soil structure and fertility, promoting plant growth and stress tolerance and maintaining a balanced ecosystem (Sathya et al, 2016;Hartmann and Six, 2023). They break down organic matter, releasing nutrients that plants can utilize (Prasad et al, 2021).…”

“…Furthermore, certain bacteria produce substances that bind soil particles together, forming small aggregates that affect water movement within the soil (Hartmann and Six, 2023). Some of them can even control the spread of pathogens in soils and indirectly promote agricultural productivity (Sathya et al, 2016). However, it is crucial to acknowledge the presence of pathogenic bacteria in soil, which can pose a danger to plants and potentially induce diseases.…”

Recently, global warming has become more visible, and the entire world is experiencing its effects. Given that global temperature is rising by 0.2 °C (± 0.1 °C) per decade, human-induced warming reached 1 °C above pre-industrial levels around 2017 and is expected to reach 1.5 °C around 2040. However, there is a lack of comprehensive data and longterm monitoring studies on how global warming might impact the diversity of bacteria in terrestrial ecosystems. Since bacteria have a specific range of temperatures for optimal growth and metabolic activity, changes in surrounding temperature may induce a change in soil temperature, leading to alterations in the diversity and composition of soil bacterial communities. Considering the vital ecological functions performed by terrestrial soil bacteria, it is crucial to understand how terrestrial bacteria respond to elevated environmental temperatures. This knowledge will facilitate the development of appropriate intervention strategies to address the anticipated depletion of beneficial bacteria and the potential increase in pathogenic soil bacteria in the upcoming years. This paper explores researchers' efforts over many years to document bacterial diversity and to forecast the impact of global warming on soil bacterial communities using various simulation systems. It also discusses potential mitigation strategies for preserving the pre-warming healthy soil bacteria communities.

“…Dryland soil health is tied to the diversity, composition, and activity of belowground microbial communities (Fierer et al., 2021). These soil microorganisms carry important ecosystem functions such as nutrient cycling (Sathya et al., 2016), soil aggregation and stabilization (Bharadwaj, 2021), and disease suppression (Chaparro et al., 2012). Previous studies have investigated and compared the effect of modern agricultural traditions (i.e., tillage, monocrops, irrigation, and chemical fertilization) and traditional management (i.e., organic fertilization, no till) on arid soil microorganisms (Ishaq et al., 2020; López‐Piñeiro et al., 2013; Melero et al., 2008; Ng et al., 2012).…”

Although soil has been a central piece in agricultural knowledge for most of recorded history, introductions of exotic plant assemblages can produce loss of soil quality, especially in more fragile ecosystems such as drylands. Here we investigate the impact of indigenous and introduced plant assemblages associated with ethno‐agricultural traditions of Tucson, AZ (USA) on soil microbial communities using 16S rRNA gene (bacteria and archaea) and ITS region (fungi) metabarcoding. We found differences in soil microbial community diversity and composition across plant assemblages associated with ethno‐agricultural traditions. However, we found the largest community structure differences between managed cultivated plots and not cultivated desert soils. Managed cultivated plots were characterized by higher diversity (23% increment for bacteria/archaea, and 40% for fungi) and a higher abundance of nitrifying bacteria (19% higher) and cellulolytic bacteria (39% higher) relative to minimally disturbed plots, suggesting higher rates of decomposition and nitrogen cycling. Given the observed influence of management on soil microbial communities, we conclude that efforts to build arid‐specific sustainable agricultural solutions would benefit from the use of adapted plants that require minimal management.This article is protected by copyright.
