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

Journal 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

Cytomolecular identification of individual wheat-wheat chromosome arm associations in wheat-rye hybrids [PDF]

, 2013
Chromosome pairing in the meiotic metaphase I of wheatrye hybrids has been characterized by sequential genomic and fluorescent in situ hybridization allowing not only the discrimination of wheat and rye chromosomes, but also the identification of the

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

Journal 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 ...

Management of vegetable crop residues for reducing nitrate leaching losses in intensive vegetable rotations [PDF]

, 2012
Crop residues of field vegetables are often characterized by large amounts of biomass with a high N-content. Despite low soil temperatures during autumn, high rates of N mineralization and nitrification still occur causing important N-losses through ...

Irrigation and phytolith formation:an experimental study [PDF]

, 2011
It has been proposed that phytoliths from archaeological sites can be indicators of water availability and hence inform about past agricultural practices (Rosen and Weiner, 1994; Madella et al., 2009). Rosen and Weiner (1994) found that the number of
