V140 Kiel: Greenhouse gas emissions and supporting temperatures 2015-2018

Nitrate surplus after harvest of winter oilseed rape and faba beans is a serious issue regarding groundwater pollution and GHG emission. Stimulation of microbial N immobilization by organic amendments might be an option to prevent N-losses and optimize N use efficiency on crop rotation level.
In this trial two crop rotations were established in a split plot design. The soil microbial activity is manipulated in field scale by post-harvest application of different organic amendments: preceding crop residues, winter wheat straw and spruce sawdust.
This file provides greenhouse gas emission rates from trial V140 on exeprimental farm Hohenschulen, Achterwehr, Germany. The trial is conducted by Uni Kiel, Institute of Crop Science and Plant Breeding, Agronomy and Crop Science. Geographical reference for the trial plots can be found in V140_Parzellen_neu.shp (join by 'Plot_ID' and 'id'). UKiel_V140_Plot_Description_2015_2018_BonaResDataCenter.csv contains detailed information about the experimental setup and the treatment of the individual plots.
The emissions have been sampled from harvest of the preceding crops till the first fertilizer application on winter wheat plots. Sampling has been done with the static closed chamber method. Calculation of flux rates has been done in R with the package 'gasfluxes'.
