Winter Wheat Digestate Experiment Emissions and Biomass Data from UK 2017

Field experiment data from 45 plots and 16 extra mini-plots at two UK research stations in 2017. Measurements include nitrogen offtake, ammonia and nitrous oxide emissions, soil parameters, and biomass production from winter wheat under various digestate and fertilizer treatments. The data was collected by Bangor University and Rothamsted Research for a BBSRC and NERC-funded nitrogen agronomy project.

Use Cases

• Model nitrogen use efficiency (NUE) using nitrogen offtake, ammonia volatilization, and nitrous oxide emissions data from digestate treatments.
• Compare grain yield and plant biomass production across control, digestate, and ammonium nitrate fertilizer treatments.
• Analyze correlations between soil parameters (pH, EC, NH4+, NO3−) and nitrogen emissions or biomass outcomes.
• Assess the impact of nitrification inhibitor DMPP on ammonia and nitrous oxide emissions for acidified and non-acidified digestate treatments.

Strengths

• Data from 45 experimental plots in a randomized complete block design, providing structured comparative analysis.
• Includes measurements for multiple key variables: nitrogen emissions, soil chemistry, and crop production.
• Covers five distinct digestate-based treatments and four rates of a standard fertilizer for comparison.

Limitations

• Temporal coverage is limited to a single growing season from April to August 2017.
• Geographic scope is restricted to two specific research sites in the UK, limiting generalizability.
• Sample size is confined to the experimental plots, not representative of commercial farm scales.
