Tracking weeds to stop them in their tracks

Not that long ago, weeds spread at a much slower rate. Seeds would spread to nearby soil and move perhaps a few feet each year or would be transplanted by birds who flew with them several miles away. In today's interconnected ...

Earthworms could help reduce antibiotic resistance genes in soil

Earthworms improve the soil by aerating it, breaking down organic matter and mineralizing nutrients. Now, researchers reporting in ACS' Environmental Science & Technology have dug up another possible role: reducing the number ...

Modeling gas diffusion in aggregated soils

Agricultural soils contribute to 16% of total Greenhouse gas emissions, particularly nitrous oxide (N2O). Migration of gases in agricultural subsurface and emission across the soil-atmosphere interface is primarily diffusion-controlled ...

Study assesses environmental impact of Ontario corn production

Researchers at the University of Guelph examined the energy use and greenhouse gas (GHG) emissions associated with corn production in Ontario. Their findings are published today in the Agricultural Institute of Canada's (AIC) ...

Estonian soil is surprisingly rich in species

Due to its biodiversity and theoretically huge number of taxa waiting to be discovered, soil fauna has been called the poor man's rain forest. If a researcher cannot head to the tropics but wishes to discover something new, ...

Help students think like soil scientists

Emphasizing cross-disciplinary concepts in teaching soil science courses, such as mass-volume relationships, can help undergraduates learn real-world, problem-solving skills that are crucial to their success in soil science ...
