Machine learning on multi‐spectral imagery to estimate nutrient yield of mixed‐species cover crops
Agricultural &Environmental Letters, Volume 10, Issue 1, June 2025.Abstract This study aimed to estimate mixed‐species cover crop (CC) biomass and nutrient contents using remote sensing, as ground‐based measurements are time‐consuming and costly. Eleven CC treatments with varying grass‐legume proportions (GLP) were sampled, and nutrient contents were determined along with multispectral imagery captured during the ...

Can gridded real‐time weather data match direct ground observations for irrigation decision‐support?
Agrosystems, Geosciences &Environment, Volume 8, Issue 2, June 2025.Abstract Agricultural decision‐support systems are commonplace in extension and outreach. These systems typically rely on either historical or direct ground observations to make grower recommendations. Sensor data create many challenges for application developers, though, including managing device‐level characteristics, ensuring observation data ...

Permafrost and Periglacial Processes, Volume 36, Issue 2, Page 205-216, April/June 2025.ABSTRACT Permafrost coasts are eroding at an accelerating pace, delivering vast amounts of sediments, organic matter, nutrients, and pollutants into the Arctic Ocean. These fluxes play a crucial role in the coastal biogeochemical cycle, yet their magnitude, as well as the trajectory and fate of the eroded material, is largely unknown.

Shrubs Strongly Influence Snow Properties in Two Subarctic Watersheds
Permafrost and Periglacial Processes, Volume 36, Issue 2, Page 189-204, April/June 2025.ABSTRACT Understanding changes in snow distribution in permafrost ecosystems is fundamental to predicting their response to future climate change. The expansion of tall shrubs into tundra ecosystems can trap snow and insulate permafrost ecosystems during the winter, but the overall insulation effect is dependent upon many ecosystem properties. To study
