AmeriFlux ecosystem observation datasets - University of Nebraska, Lincoln, Agricultural Research Service rainfed maize-soybean rotation site

posted on 2023-11-30, 08:44 authored by Andy Suyker, Sashi Verma, Todd Schimelfenig

The study site is one of three fields (all located within 1.6 km of each other) at the University of Nebraska Agricultural Research and Development Center near Mead, Nebraska. While the other two sites are equipped with irrigation systems, this site relies on rainfall. A tillage operation (disking) was done just prior to the 2001 planting to homogenize the top 0.1 m of soil, incorporate P and K fertilizers, as well as previously accumulated surface residues. Since initiation of the study in 2001, this site has been under no-till management.

Intended use

AmeriFlux Community Goals Quantify the magnitude of the carbon sources and sinks for a range of terrestrial ecosystems in the Americas, and how they may be influenced by disturbance, management regimes, climate variability, nutrients, and atmospheric pollutants; Advance understanding of processes regulating carbon assimilation, respiration, and storage; Collect critical new information to help define the current global CO2 budget; Enable improved predictions of future concentrations of atmospheric CO2
