Linking Plant and Soil Microbial Diversity via Plant Functional Trait Ecology
… functioning, yet our understanding of how plant diversity relates to soil microbial diversity remains rudimentary. Cover crops are increasingly promoted for their potential to enhance soil health and microbial diversity in agroecosystems, but variability in their effects highlights the need for a …

Soil Microbial Diversity and Litter Decomposition Increase with Time Since Land Use Disturbance in Tropical Montane Forests of Malaysian Borneo
… of Southeast Asia. These disturbances alter soil chemistry, microbial diversity, and disrupt carbon cycling through shifts in litter decomposition. Direct links between microbial diversity and soil properties such as pH are well established; however, the indirect impacts of logging and forest …

Global meta-analysis and metagenomics approach on the soil microbiome associated with cover cropping
Soil nutrient loss is one of the major causes of soil degradation that threatens future global food security. Cover cropping is a promising sustainable agricultural method with the potential to enhance soil health and mitigate consequences of soil degradation. As one of the agricultural practices …

Regenerative agriculture and soil carbon storage in the Upper Corn Belt
… conversion, agricultural mismanagement, and topsoil erosion have depleted global soil organic carbon (SOC) stocks in the top two meters of soil by an estimated 133 petagrams (Pg), resulting in a significant SOC debt. Regenerative cropping practices, such as no-till and cover cropping, are …

The effects of warming on carbon and microbial community wetland dynamics at Turnbull National Wildlife Refuge, Washington
… across hydroperiods and treatment by measuring soil organic carbon (in Summer 2018) and effluxes of carbon dioxide and methane (in Summer 2018, Fall 2018, and Spring 2019). I found no differences across wetland type or warming treatment in soil organic carbon. Results also showed that when …

Microbial diversity and activity in temperate forest and grassland ecosystems
Ecosystems currently face widespread biodiversity losses and other environmental disturbances, such as climate warming, related to increased anthropogenic activities. Within this context, scientists consider the effects of such changes on the biodiversity, and hence on the activity, of soil …

Legacy effects of cover crop monocultures and mixtures on soil inorganic nitrogen, total phenolic content, and microbial communities on two organic farms in Illinois
… crops can leave behind legacy effects on their soil environments by influencing soil inorganic nitrogen (N) pools, total phenolic content through the release of secondary compounds, and by altering soil microbial communities. I analyzed soils collected during a two-year field study and aimed to …
