• Beyond Soil Health: The Microbial Implications of Conservation Agriculture (2025) · Diversity · cited 7× · doi

  Although extensive information regarding the effect of CA on soil properties and microbiome is available, complete studies on the cumulative effect on specific interactions between soil parameters, crop productivity, and microbial communities over time are still lacking, mainly in arid regions.

• Association between bacterial community and cadmium distribution across Colombian cacao crops (2024) · Microbiology Spectrum · cited 7× · doi

  Although microbes have been shown to metabolize and drive the speciation of Cd under controlled conditions, regardless of the link between soil bacterial community (SBC) dynamics and Cd mobilization in the rhizosphere, only a few studies have addressed the relationship between soil bacterial community composition (SBCC) and Cd content in cacao seeds (Cd seed ).

• Host genotype-enriched rhizosphere microbes enhance pea (Pisum sativum L.) yield (2026) · Plant and Soil · doi

  Aims The rhizosphere microbiota is critical for crop productivity, but the mechanisms by which host genotype shapes microbial communities to influence yield, especially in legumes, are not well understood.
