Short summary
Short summary
Our study explores Enhanced Weathering (EW) using basalt rock dust to combat climate change. We treated corn-planted mesocosms with varying basalt amounts and monitored them for 101 days. Surprisingly, we found no significant inorganic carbon dioxide removal (CDR). However, rock weathering was evident through increased exchangeable bases. While immediate inorganic CDR benefits were not observed, basalt amendment may enhance soil health and potentially long-term carbon sequestration.

This study explored how adding crushed basalt and biochar to soil affects plant growth, soil carbon emissions, and plant trace metal uptake. While basalt alone increased carbon dioxide release from soil, combining it with biochar reduced this effect. Biochar also boosted plant growth and lowered the amount of trace metals taken up by crops. These findings suggest that using biochar with basalt may improve soil health and help manage environmental risks.

Short summary
Enhanced rock weathering is a nature based negative emission technology, that permanently stores CO2. It requires rock-flour to be added to arable land with the help of farmers. To be eligible for carbon credits calls for a simple but scientifically solid, so called, Monitoring, Reporting & Verification” (MRV). We demonstrate that the commonly used carbon-based accounting is ill-suited to close the balance in open systems such as arable land, and argue for cation-based accounting strategy.

In subarctic grassland on a geothermal warming gradient, we found large reductions in topsoil carbon stocks, with carbon stocks linearly declining with warming intensity. Most importantly, however, we observed that soil carbon stocks stabilised within 5 years of warming and remained unaffected by warming thereafter, even after > 50 years of warming. Moreover, in contrast to the large topsoil carbon losses, subsoil carbon stocks remained unaffected after > 50 years of soil warming.

Zea mays grows in mesocosms with different soil nutrition levels. At low phosphorus (P) availability, leaf physiological activity initially decreased strongly. P stress decreased over the season. Arbuscular mycorrhizal fungi (AMF) symbiosis increased over the season. AMF symbiosis is most likely responsible for gradual reduction in P stress.

We provide a comprehensive dataset of vertical profiles of photosynthesis and important leaf traits, including leaf N and P concentrations, from two 3-year, large-scale nutrient addition experiments conducted in two tropical rainforests in French Guiana. These data present a unique source of information to further improve model representations of the roles of N and P, and other leaf nutrients, in photosynthesis in tropical forests.

Short summary
A mesocosm experiment was set up to investigate how maize responds to the application of basalt, concrete fines, and steel slag, using a dose–response approach. Biomass increased with basalt application but did not change with concrete fines or steel slag, except for increased tassel biomass. Mg, Ca, and Si generally increased in the crops, whereas toxic trace elements remained unaffected or even decreased in the plants. Overall, crops were positively affected by the application of silicate materials.
