“…In this observational study, microbial communities of managed soils had increased microbial diversity and abundance of functional groups related to nitrogen cycling compared to dryland soils. Managed soils could potentially produce higher crop yields, but also could experience a shift in soil properties (Hall et al., 2011), long‐term depleted stable pools of nutrients such as C and N (Emmett et al., 1998), and more favorable conditions for the establishment of invasive plant species (Rembelski & Fraterrigo, 2023). These systems will therefore depend on continuous irrigation and fertilization or else be vulnerable to desertification.…”

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.
