Irrigation and Drainage, EarlyView.ABSTRACT This research investigated soybean soil water dynamics under different irrigation levels in three different soil types in the same field concurrently. Treatments imposed in each soil type were: (i) variable‐rate irrigation (VRI), (ii) fixed‐rate full irrigation (FRI‐1″ or FRI‐25.4 mm) and (iii) fixed‐rate limited irrigation (FRI‐0.75″ or FRI ...

Journal of Environmental Quality, EarlyView.Abstract Nordic agriculture faces big challenges to reduce phosphorus (P) loss from land to water for improving surface water quality. While understanding the processes controlling P loss and seeking for P mitigation measures, Norwegian and Swedish researchers have substantially benefited from and been inspired by Dr.

Optimal Scheduling for Broadcast Erasure Channels with Energy Harvesting Receivers [PDF]
, 2015 In this paper, an optimal scheduling for broadcasting packets to two receivers over erasure channels with feedback is studied. We propose a probabilistic algorithm for packet broadcasting to two receivers, and it is demonstrated that the algorithm is ...

Connecting the soil health–water quality nexus under surface‐irrigated conservation tillage
Journal of Environmental Quality, EarlyView.Abstract Intense tillage degrades soil health, worsens soil structure, and accelerates nutrient and sediment transport to vulnerable water bodies. Unfortunately, few studies have measured both soil health and water quality under conservation tillage, particularly in semi‐arid furrow‐irrigated fields, limiting our understanding of tillage impacts in ...

Measurement of nitrous oxide soil fluxes using sorbent‐stabilized sampling of flux chambers
Journal of Environmental Quality, EarlyView.Abstract A new chamber‐based method to measure nitrous oxide soil gas fluxes using an N2O sorbent is presented. The Greenhouse Gas Reduction through Agricultural Carbon Enhancement network (GRACEnet) protocols require grab samples (typically 25 mL ea.) obtained at multiple intervals throughout chamber deployment (i.e., 0, 15, and 30 min) and linear and
