Cover crops and nitrogen rates: Impacts on no‐till corn and soil health in Louisiana

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Use of cover cropping systems to improve soil health is still limited in Louisiana. This study aimed to examine the interaction between cover crops and nitrogen (N) fertilizer rates on crop yield, soil chemical, and biological properties. Winter cover crop treatments, including legumes, a grass and brassica, and a fallow control, were combined

Soil amendment effects on field‐saturated and unsaturated hydraulic properties of sodic soils

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Soil sodicity degrades soil structure and restricts water movement by promoting clay swelling, dispersion, and surface sealing, thereby reducing infiltration and hydraulic conductivity. This study aims to evaluate the effects of four soil amendments (elemental sulfur, gypsum, compost, and humate) on the hydraulic conductivity of sodic soils ...

Assessing forage mass using smartphone imagery for cereal rye under grazing conditions in Nebraska

open access: yesCrop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract Managing grazing efficiency requires reliable and practical tools to estimate forage mass. Traditional methods like clipping, though accurate, are time consuming and labor intensive. In this study, two imaging tools, Canopeo and the Crop Canopy Image Analyzer (CCIA), were evaluated for their efficacy in estimating the forage mass of cereal rye

Should cotton growers apply full nitrogen rate when using broiler‐litter as soil amendment?

open access: yesCrop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract Nitrogen plays a critical role in cotton (Gossypium hirsutum L.) production. Interest in using broiler (Gallus gallus domesticus) litter has increased in recent years due to its nutrient and soil health benefits. However, growers typically do not discount the N present in broiler litter and apply a full dose of fertilizer N.

Phylogenetic relationships among Secale species revealed by amplified fragment length polymorphisms

open access: yes, 2005
Amplified fragment length polymorphism (AFLP) data were utilized to analyze the phylogenetic relationships among 29 accessions representing 14 of the most commonly recognized ranked species or subspecies in the genus Secale. We observed 789 AFLP markers

Efficient Automatic Pollen Recognition From Fossil Pollen Samples: A High‐Resolution Example Record From Palaeolake Kieshofer Moor, Northeastern Germany

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
We applied the two‐stage, AI‐based TOFSI approach to test automatic pollen recognition with fossil pollen samples. The algorithm performs very well for all major pollen types and other non‐pollen object classes, suggesting that such tools have the potential to substantially increase the efficiency of pollen analysis.
