Establishing Biodigestate Based Fertilizer's Value Within the Agricultural Community: A Key Prerequisite of Bioenergy Commercial Viability

New Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.
This research investigated the barriers and opportunities for biodigestate, a key by product of bioenergy production, as an input to commercial agricultural operations within New Zealand. The qualitative research examined in detail how the product fitted into the agricultural community.

Exploring the Wolf Approach to Constraining NIR Extinction Laws in the Corona Australis Molecular Cloud

The Astronomical Journal
The viability of the star count (Wolf) method is assessed as a means of constraining the near-infrared (NIR) extinction law toward the Corona Australis molecular cloud. Using deep JHK _S photometry from the VISIONS survey, extinction maps with 1′ spatial

Extinction law and stellar mass in the nuclear bulge from kinematically selected red clump stars

Astronomy & Astrophysics
Context. The nuclear bulge of the Milky Way harbors stellar populations that provide crucial insights into galaxy formation processes and serve as a nearby analog for understanding bulge formation in external galaxies.

Assessing corn response to sulfur fertilization in Kansas: Efficiency, optimum rate, and diagnostic tools

Agronomy Journal, Volume 118, Issue 2, March/April 2026.
Abstract Corn (Zea mays L.) response to sulfur (S) fertilizations remains difficult to assess due to the dynamic nature of S availability. This study evaluated corn response and diagnostic tools across 30 field sites in Kansas (Experiment 1; with and without S) and in complementary rate trials at two sites (Experiment 2; multiple S rates). Measurements

Formation Process of the Young Stellar Population in Messier 16 from a Kinematic Perspective

The Astronomical Journal
We present a kinematic study of young stars in Messier 16 (M16) using the Gaia Data Release 3 and high-resolution spectra. A total of 345 stars are selected as genuine members using the published lists of X-ray sources, infrared sources, and early-type ...

The Bochum Survey of the Southern Galactic Disk: III. Complete Data Release

Astronomische Nachrichten, Volume 347, Issue 3, March 2026.
ABSTRACT The Southern Galactic Disk Survey (GDS) monitored a mosaic of 268 fields along a 6°$$ {6}^{{}^{\circ}} $$‐wide stripe in the southern Galactic disk with simultaneous observations in r′$$ {r}^{\prime } $$ and i′$$ {i}^{\prime } $$ (7m≲r′,i′≲18m$$ {7}^{\mathrm{m}}\lesssim {r}^{\prime },{i}^{\prime}\lesssim {18}^{\mathrm{m}} $$) from September ...

Extinction of Taurus, Orion, Perseus and California Molecular Clouds Based on the LAMOST, 2MASS, and Gaia Surveys. II. The Extinction Law

The Astronomical Journal
The extinction law from ultraviolet (UV) to infrared (IR; 0.2–24 μ m) is determined by relying on the blue-edge method and color-excess ratios for some nearby molecular clouds, from the low-mass star-forming region to the massive star-forming region. The

Cepheid Metallicity in the Leavitt Law (C–MetaLL) survey

Astronomy & Astrophysics
Context. The C-MetaLL project has provided homogeneous spectroscopic abundances of 290 Classical Cepheids (DCEPs) for which we have the intensity-averaged magnitudes in multiple optical and NIR bands, periods, pulsation modes, and Gaia parallaxes ...

Critical Slowing Down Reveals Hydrologic Resilience Loss Across Amazon Sub‐Basins

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract The Amazon's hydroclimate exhibits basin‐scale early‐warning signals of critical slowing down (CSD), a statistical signature of declining resilience as systems approach critical transitions. We apply a multi‐metric framework to precipitation, evapotranspiration, Soil moisture (SM), and extreme streamflows, tracking rolling variance, lag‐1 ...

Uniform Forward-modeling Analysis of Ultracool Dwarfs. III. Late-M and L Dwarfs in Young Moving Groups, the Pleiades, and the Hyades

The Astrophysical Journal
We present a uniform forward-modeling analysis of 90 late-M and L dwarfs in nearby young (∼10–200 Myr) moving groups, the Pleiades, and the Hyades using low-resolution ( R ≈ 150) near-infrared (0.9–2.4 μ m) spectra and the BT-Settl model atmospheres.
