Characterizing the fine‐scale spatial distribution of soil phosphorus for efficient phosphorus management in an Illinois tile‐drained field

open access: yesJournal of Environmental Quality, EarlyView.
Abstract Closed depressions in post‐glacial landscapes can accumulate phosphorus (P) due to repeated flooding and become hotspots for P loss when underlain by subsurface (tile) drainage. Soil P mapping is routinely based on the interpolation of samples from a 1‐ha grid, which may miss closed depressions and underestimate soil P levels leading to ...

The BELSAR dataset: Mono- and bistatic full-pol L-band SAR for agriculture and hydrology

open access: yesScientific Data
The BELSAR dataset consists of high-resolution multitemporal airborne mono- and bistatic fully-polarimetric synthetic aperture radar (SAR) data in L-band, alongside concurrent measurements of vegetation and soil biogeophysical variables measured in maize

Testing Wisconsin P index assessments across cropping systems

open access: yesJournal of Environmental Quality, EarlyView.
Abstract Managing agricultural runoff phosphorus (P) often requires understanding management effects on both dissolved P (DP) and particulate (sediment‐bound) P (PP). The Wisconsin P index (WPI) allows producers to assess land management effects on runoff P by estimating annual P losses in mass per unit area.

Utility of near‐surface phenology in estimating productivity and evapotranspiration across diverse ecosystems

open access: yesJournal of Environmental Quality, EarlyView.
Abstract Agroecosystems, which include row crops, pasture, and grass and shrub grazing lands, are sensitive to changes in management, weather, and genetics. To better understand how these systems are responding to changes, we need to improve monitoring and modeling carbon and water dynamics.

Challenges in dating blanket peat and implications for understanding its initiation in Ireland

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Blanket peat is widespread in maritime extra‐tropical environments. Prehistoric land‐use activity was traditionally invoked as the stimulus of blanket peat initiation in the British Isles, but recently, climate has been viewed as the driver of peat formation.

Agent-based modeling on interaction between water and labor availability in rainfed rice ecosystem, northeast Thailand [PDF]

open access: yes, 2008
An Agent-Based Model (ABM) was co-designed with local rice farmers to represent the human-environment interactions between land/water use and labor management. A rainfed area of Ubon Ratchathani Province, Thailand was the study site.

Effects of (Assisted) Natural Regeneration on Infiltrability and Preferential Flow Pathways in the Khasi Hills (Meghalaya, NE India)

open access: yesLand Degradation &Development, Volume 36, Issue 5, Page 1564-1578, March 2025.
ABSTRACT Intensified slash‐and‐burn cultivation and forest clearing have caused severe land degradation in the Khasi Hills (Meghalaya plateau, NE India). Despite very high annual rainfall, the region faces severe water scarcity during the dry season.
