Crop sequencing effects of seven crops on grain yield, volunteers, and weeds in Saskatchewan

Agronomy Journal, Volume 118, Issue 5, September/October 2026.
Abstract Every growing season, producers must decide which crops to grow and in what sequence to enhance returns and sustain productivity. However, when producers consider growing specialty crops like canary seed (Phalaris canariensis L.), coriander (Coriandrum sativum L.), hemp (Cannabis sativa L.), or quinoa (Chenopodium quinoa Willd.), data are ...

Improving carbon modeling in aspen‐dominated forests: Lessons from CBM‐CFS3 evaluation against long‐term field data

Ecological Applications, Volume 36, Issue 6, September 2026.
Abstract Boreal forests cover a substantial portion of Canada's land base and play a central role in the national carbon budget through carbon storage and fluxes across multiple above‐ and belowground pools. The Carbon Budget Model of the Canadian Forest Sector (CBM‐CFS3) simulates and projects forest carbon dynamics under varying conditions and ...

Linear Water Erosion in the State of Mato Grosso (Brazil): Spatial Analysis and Identification of Critical Areas

Earth Surface Processes and Landforms, Volume 51, Issue 9, September 2026.
Mapping linear water erosion across Mato Grosso revealed spatially concentrated critical areas rather than a uniform distribution. Erosion foci were more frequent in environmentally fragile landscapes and areas of land‐use conflict, highlighting where monitoring and soil‐conservation actions should be prioritized.

Comparative characteristics of the properties of Halpic Chernozem of the Kursk Region of different land use [PDF]

, 2020
Analytical data show that prolonged extensive agricultural use of typical Chernozem of Kursk region (Haplic Chernozem) results in adverse changes in some soil properties. This primarily concerns the humus content and the structural state of the Chernozem.
