Nitrogen dynamics and physiological N use efficiency in high‐biomass sorghum

Agricultural &Environmental Letters, Volume 11, Issue 1, June 2026.
Abstract Improving nitrogen (N) efficiency is essential for sustainable high‐biomass sorghum (Sorghum bicolor L. Moench) production. This study evaluated leaf and stem N dynamics, canopy N remobilization, and physiological nitrogen use efficiency (pNUE) in two photoperiod‐sensitive sorghum hybrids under two N rates (0 and 168 kg‐N ha−1) across multiple

World Technology Usage Lags [PDF]

We present evidence on the differences in the intensity with which ten major technologies are used in 185 countries across the world. We do so by calculating how many years ago these technologies were used in the U.S.

Quantifying the land‐use change due to soybean‐based biodiesel in the United States

Applied Economic Perspectives and Policy, Volume 48, Issue 1, Page 20-47, March 2026.
Abstract We quantify the impact of soybean oil‐based biodiesel production on US cropland, using a method that accounts for the intermediate effect of soybean crushing facilities. Based on U.S. Environmental Protection Agency data for biodiesel production and proprietary data for soybean crushing facilities over 2011–2020, we find that the elasticities ...

Field assessment of nitrogen sources in Brassica carinata using physiological indicators of nitrogen status under temperate no‐till conditions

Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.
Abstract Improving nitrogen (N) use efficiency in Brassica carinata is essential to sustain yield and lower biofuel carbon intensity under variable field conditions. We hypothesized that integrating physiological indicators, such as the nitrogen nutrition index (NNI) and the critical nitrogen uptake curve (CriNUC), into N management frameworks would ...

Field Evaluation of Different Unmanned Aerial Spraying Systems Applied to Control Panonychus citri in Mountainous Citrus Orchards

Agriculture
In mountainous citrus orchards, the application of conventional ground sprayers for the control of citrus red mite (Panonychus citri) is often constrained by complex terrain and low operational efficiency.

Economics of land‐based carbon mitigation

American Journal of Agricultural Economics, Volume 108, Issue 2, Page 443-461, March 2026.
Abstract Agricultural land holds tremendous potential to contribute to net zero greenhouse gas emission goals by providing low carbon renewable energy to displace fossil fuels and by serving as a sink for sequestering carbon in the soil with climate‐smart practices. This potential is, however, far from being realized.

Quantifying the Relative Impact of Atmospheric Variables and Polynya Dynamics on Fast Ice in Terra Nova Bay, Antarctica

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Antarctic fast ice in Terra Nova Bay is crucial for regional climate, ecosystems, and scientific logistics but has recently shown unprecedented decline, impacting operations at Jang Bogo Station. Despite its significance, there remains limited predictive understanding of Antarctic fast ice dynamics, especially regarding thickness and stability, with ...

Question the Mark: A Review and Assessment of Bat Marking Practices

Mammal Review, Volume 56, Issue 1, March 2026.
We reviewed a decade of research on bats and conducted a broader systematic review to assess the nature of bat marking practices and the effects and efficacy of marks. Effects of marks on bats, mark details and marking procedures are rarely reported and further research on the effects of marks on bats and more thorough reporting are needed.

Understanding the dynamic nature of plant lipid anabolic and catabolic metabolism is key to sustainable oilseed engineering

New Phytologist, Volume 249, Issue 5, Page 2196-2214, March 2026.
Summary Plant‐derived oils are essential sources of reduced carbon and various fatty acid (FA) structures for food, biofuels, and the oleochemical industry. Despite extensive efforts, engineering mainstream oilseed crops to produce high levels of industrially valuable unusual FAs (UFAs) remains challenging.
