No-till and mulching are typical management operations in conservation agriculture (CA). To model pesticide degradation and leaching under a CA scenario, as compared to a conventional-tillage scenario (CT), the mulch module of the agro-hydrological model Daisy was extended. A Daisy soil column was parameterized with measurements of topsoil, mulch, and a realistic subsoil, and tested against published experimental data of pesticide fate in laboratory soil columns covered by mulch.

This study presents the first mechanistic model for describing the generation and environmental fate of a natural toxin, i.e.

In this study, we constructed two monitoring transects along the nitrogen-polluted Shaying River, China. The GW-SW interactions were qualitatively and quantitatively characterized through an intensive 2-y monitoring program.

- Phytotoxins, specifically toxic alkaloids, are produced by lupins and other Fabaceae family plants, but their environmental effects remain largely unexplored.
- A field experiment measured the presence of these alkaloids in various samples including lupin tissues and drainage water, with lupanine being the most prevalent compound detected.
- The cumulative amount of alkaloids found in drainage water was minimal compared to the total in lupin biomass, but significant amounts were transported during heavy rainfall, highlighting potential contamination risks for surface water in agricultural regions.
Background: There is a knowledge gap in whether psychopathology aspects can shape and mark the social representations about health and lifestyle. In this work, we investigated the association of psychopathology and shame with the centrality of the words describing eight common social representations of health and lifestyle.
Methods: A convenience sample of 288 adults participated with an average age of 44.
