Accumulation of phosphorus fractions in contrasting soils under long‐term phosphate fertilization

open access: yesJournal of Environmental Quality, Volume 55, Issue 1, January/February 2026.
Abstract Understanding phosphorus (P) dynamics in soils under conservation agriculture remains challenging because the long‐term effects of fertilization rates and soil texture on P accumulation, availability, and environmental risk are not being fully understood. This study evaluated P fraction accumulation and saturation indices across soil layers in

Linking remote sensing with crop modeling for yield and nitrate leaching predictions in Minnesota

open access: yesJournal of Environmental Quality, Volume 55, Issue 1, January/February 2026.
Abstract Upscaling crop yield and nitrate‐N leaching loss from experimental sites to large areas under alternative crop rotations is crucial for assessing strategies and setting goals to protect groundwater quality at a regional scale. Nitrogen (N) rate field trials were used to calibrate the Environmental Policy Integrated Climate (EPIC) model for ...
