Assessment of corn chlorophyll content via UAV‐derived vegetative indices across growth stages

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 4, December 2026.
Abstract Traditional chlorophyll (Chl) assessment methods are labor‐intensive and spatially limited. This study evaluated unmanned aerial vehicle (UAV) multispectral imagery for nondestructive field‐scale canopy Chl estimation in corn (Zea mays L.) to support precision nutrient management.

Slow‐release peat‐urea fertilizer increased sweet corn yield and nitrogen use efficiency compared to urea

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 4, December 2026.
Abstract Nitrogen (N) use efficiency of urea is often low, resulting in inefficient N utilization. Again, peat, a high organic carbon (OC)‐containing soil, is considered a problematic soil. However, enriching peat with urea may release fertilizer N slowly, and its application to agricultural soil can sequester OC in the soil.

Emissions variability of greenhouse gases within and between sites during late‐season corn production in Mississippi

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 4, December 2026.
Abstract Variability of greenhouse gas (GHG) fluxes and emissions among replicates in a study area can have an impact on results depending on the statistical tools used to assess significant differences among fixed effects. The objective of this study was to assess the effect of site and time (i.e., date) and the variability within and between sites on

Herbage components in nitrogen‐fertilized and legume‐containing double‐cropped annual and perennial forages in eastern Nebraska

open access: yesCrop, Forage &Turfgrass Management, Volume 12, Issue 2, December 2026.
Abstract Diverse perennial circular systems that focus on grazing offer many environmental benefits. However, the use of annual forages may be necessary where perennial pastures have declined. Our study sought to evaluate herbage components in a double‐cropped annual forage experiment with triticale [×Triticosecale Wittm. ex A. Camus (Secale × Triticum)

Developing a Climate Impact Indicator Framework for the UK Agri‐Food Sector: A Literature Review and Stakeholder Co‐Production Approach

open access: yesClimate Resilience and Sustainability, Volume 5, Issue 2, December 2026.
The paper outlines the methodology followed in choosing five key indicators which will be used in a forthcoming annual review of the impact of weather and climate on the UK agri‐food sector. This is done through an initial literature review, a synthesis of the currently understood impacts of weather and climate, and insights from group of experts and ...
