Mitigating the soil carbon deficit of annual agriculture with perennial bioenergy crops in the U.S. Midwest

I. B. Kantola, Yuhei Nakayama, Ezra Moses, Elena Blanc‐Betes et autres

Maize ( Zea mays L.) is the dominant bioenergy feedstock in the US Midwest but its cultivation since the early 1800s has incurred substantial losses in soil organic carbon (SOC). We quantified differences in SOC stocks under perennial bioenergy crops of Panicum …

N 2 Onet: a global collaborative network facilitating advances in measurement, modeling, and mitigation of agricultural soil nitrous oxide emissions

Wendy H. Yang, Kaiyu Guan, Evan H. DeLucia, Claudia Wagner‐Riddle et autres

Abstract Nitrogen (N) fertilizer supports global food production, but its use and overuse drive emissions of nitrous oxide (N 2 O), a potent and long-lived greenhouse gas. Understanding the drivers of N 2 O fluxes remains elusive, making it difficult to predict …

Effects of rock amendment on soil physicochemical properties and organic carbon stabilization

Evelin Pihlap, Noemma Olagaray, Tobias Klöffel, Michael D. Masters et autres

Enhanced mineral weathering in agricultural settings is an approach for carbon dioxide removal in which crushed silicate rocks are added to soils. However, the effects of long-term application of crushed basalt on soil structure and organic carbon stabilization are still poorly constrained. …

A 13‐Year Record Indicates Differences in the Duration and Depth of Soil Carbon Accrual Among Potential Bioenergy Crops

I. B. Kantola, Elena Blanc‐Betes, Adam C. von Haden, Michael D. Masters et autres

ABSTRACT Six years after replacing a maize/soybean cropping system, perennial grasses miscanthus (Miscanthus × giganteus) and switchgrass (Panicum virgatum), and a 28‐species restored prairie increased particulate organic carbon in surface soils without increasing soil organic carbon (SOC). To resolve potential changes in …

Iron Chelation in Soil: Scalable Biotechnology for Accelerating Carbon Dioxide Removal by Enhanced Rock Weathering

Dimitar Z. Epihov, Steven A. Banwart, S. P. McGrath, David P. Martin et autres

High Resolution Image Download MS PowerPoint Slide Enhanced rock weathering (EW) is an emerging atmospheric carbon dioxide removal (CDR) strategy being scaled up by the commercial sector. Here, we combine multiomics analyses of belowground microbiomes, laboratory-based dissolution studies, and incubation investigations of …

Effects of enhanced mineral weathering on soil structure and organic carbon storage

Evelin Pihlap, Noemma Olagaray, Tobias Klöffel, Michael D. Masters et autres

Enhanced mineral weathering is a nature-based solution to reduce atmospheric and soil CO2 concentrations in agricultural settings. Spreading finely grained basalt on the soil leads to subsequent chemical reactions that alters soil properties by changing soil pH, nutrient availability and particle-size distribution. …

Microbial-explicit processes and refined perennial plant traits improve modeled ecosystem carbon dynamics

Danielle M. Berardi, Melannie D. Hartman, Edward Brzostek, Carl J. Bernacchi et autres

Globally, soils hold approximately half of ecosystem carbon and can serve as a source or sink depending on climate, vegetation, management, and disturbance regimes. Understanding how soil carbon dynamics are influenced by these factors is essential to evaluate proposed natural climate solutions …

Enhanced weathering in the US Corn Belt delivers carbon removal with agronomic benefits

David J. Beerling, Dimitar Z. Epihov, I. B. Kantola, Michael D. Masters et autres

Terrestrial enhanced weathering (EW) of silicate rocks, such as crushed basalt, on farmlands is a promising scalable atmospheric carbon dioxide removal (CDR) strategy that urgently requires performance assessment with commercial farming practices. We report findings from a large-scale replicated EW field trial …

Validating assumptions in calculating carbon dioxide removal by enhanced rock weathering in Kantola et al., 2023

Adam Wolf, Elliot Chang, I. B. Kantola, Elena Blanc‐Betes et autres

Reershemius and Suhrhoff (2023) have identified some concerns with Kantola et al. (2023). We wish to point out that Reershemius and Suhrhoff find no fault with the derivation in the paper (equations 3–6), which are factually true by inspection. Reershemius and Suhrhoff …

Improving nitrogen cycling in a land surface model (CLM5) to quantify soil N 2 O, NO, and NH 3 emissions from enhanced rock weathering with croplands

Maria Val Martin, Elena Blanc‐Betes, Ka Ming Fung, Euripides P. Kantzas et autres

Abstract. Surficial enhanced rock weathering (ERW) is a land-based carbon dioxide removal (CDR) strategy that involves applying crushed silicate rock (e.g., basalt) to agricultural soils. However, unintended biogeochemical interactions with the nitrogen cycle may arise through ERW increasing soil pH as basalt …

Improved net carbon budgets in the US Midwest through direct measured impacts of enhanced weathering

I. B. Kantola, Elena Blanc‐Betes, Michael D. Masters, Elliot Chang et autres

Abstract Terrestrial enhanced weathering (EW) through the application of Mg‐ or Ca‐rich rock dust to soil is a negative emission technology with the potential to address impacts of climate change. The effectiveness of EW was tested over 4 years by spreading ground …
