Response of three cereal crops in continuous arable or ley‐arable rotations to fertilizer nitrogen and soil nitrogen at Rothamsted's Woburn Ley‐arable experiment

Soil Use and Management, Volume 39, Issue 2, Page 771-784, April 2023., 2023
Abstract Rothamsted's Woburn Ley‐arable experiment, started in 1938 on a sandy loam soil, provides valuable real‐world data on the effects of all‐arable and ley‐arable rotations. In this study, six rotations were compared from 1973 to 2001. Two had 3‐year arable “treatment” crops, two had 3‐year leys, and two had 8‐year leys; the leys being all‐grass ...

Measuring “Weather Whiplash” Events in North America: A New Large‐Scale Regime Approach

Journal of Geophysical Research: Atmospheres, Volume 127, Issue 17, 16 September 2022., 2022
Abstract The term “weather whiplash” was recently coined to describe abrupt swings in weather conditions from one extreme to another, such as from a prolonged, frigid cold spell to anomalous warmth or from drought to heavy precipitation. These events are often highly disruptive to agriculture, ecosystems, and daily activities. In this study, we propose

Molecular modelling of sorption processes of a range of diverse small organic molecules in Leonardite humic acid

European Journal of Soil Science, Volume 71, Issue 5, Page 831-844, September 2020., 2020
Abstract Soil organic matter (SOM) is abundant in the environment and plays an important role in several biogeochemical processes, including microbial activity, soil aggregation, plant growth and carbon storage. One of its key functions is the retention and release of various chemical compounds, primarily governed by the sorption process, which ...
