Seasonal leachate organic carbon and total nitrogen in an organic integrated crop–livestock rotation system

open access: yesAgricultural &Environmental Letters, Volume 11, Issue 2, December 2026.
Abstract Integrated crop–livestock systems (ICLS) can reduce nutrient losses relative to annual cropping, yet seasonal dynamics of dissolved organic carbon (DOC) and nitrogen in organic systems remain poorly understood. We evaluated non‐purgeable organic carbon (NPOC), total nitrogen (TN), and C:N ratios during the sixth and seventh years of a ...

Soil organic carbon increased after 3 years in organic grain systems differing in tillage and organic inputs

open access: yesAgricultural &Environmental Letters, Volume 11, Issue 2, December 2026.
Summary of soil organic carbon (SOC) responses to contrasting organic grain management systems after three years. SOC stocks increased across soil depths (0–60 cm) relative to baseline conditions, while active carbon fractions (POXC, WEOC, and MBC) in the surface soil layer responded to differences in cropping system management strategies.

Assessing short‐stature corn hybrids for irrigated Mid‐South production systems

open access: yesAgricultural &Environmental Letters, Volume 11, Issue 2, December 2026.
Abstract Short‑stature (SS) corn (Zea mays L.) hybrids represent an emerging phenotype with distinct morphological characteristics, but their performance under irrigated Mid‑South conditions is not well documented. We compared two SS hybrids (H1 and H2) and three tall‐stature (TS) hybrids (H3, H4, and H5) over two seasons.

Partitioning soil respiration refines carbon intensity estimates by isolating soil carbon mineralization from root respiration

open access: yesAgricultural &Environmental Letters, Volume 11, Issue 2, December 2026.
Chamber‐based root exclusion partitions total soil respiration (RT) into autotrophic (RA) and heterotrophic (RH) components in switchgrass and corn systems. Biometric carbon intensity (CI) estimated from RH reveals switchgrass as a net soil C sink (−1.95 Mg CO2‐eq Mg−1 harvested biomass) and corn as a net source (+0.68 Mg CO2‐eq Mg−1).
