General information about data set: Biomass availability from the harvest of crop residues and oilseed radish as an intermediate crop at yield survey district level in Sweden		
		
This document explains the variables presented in the textfile "Database_CropResid_IntermCrop_CarbonBal.tsv" and in the GeoPackage and Shapefile named "Data_residues_Intermediate_crops_and_carbon_balance".
The files contain the same results but the GeoPackage and Shapefile include spatial information about the Swedish yield survey districts (SKO). The Shapefile consists of the following files:

Skördeområden_biomasss_carbon.cpg
Skördeområden_biomasss_carbon.dbf
Skördeområden_biomasss_carbon.prj
Skördeområden_biomasss_carbon.sbn
Skördeområden_biomasss_carbon.sbx
Skördeområden_biomasss_carbon.shp
Skördeområden_biomasss_carbon.shx

The original geospatial data for the SKO boundaries in shapefile format was obtained from Jordbruksverket. This dataset is subject to a Creative Commons license (https://creativecommons.org/licenses/by/4.0/deed.sv), permitting sharing and processing with acknowledgment of the source (CC BY 4.0).
The table of contents of the original file was modified to asociate the results of the study to each of the polygons depicting the boundaries of the yield survey districts (SKO).

The labels of the variables include the units used: tonnes (t), hectares (ha), square kilometers (km2), or percentage (%)		
		
		
Definitions and abbreviations		
		
Term or abbreviation	Definition	
Arable land:	Share of agricultural land used, or that can be used, for crop cultivation (Exclude permanent pastures)	
Cereal straw:	Residues left by production of spring and winter cereals: wheat, barley, oats, rye, triticale, and mixed grain	
IC:	Intemediate crop	
Land under rotation:	Assumed fraction of arable land under crop rotation. This excludes grazing pastures (betesvall)	
Legume residues:	Residues from the production of peas, canned peas, and faba beans	
Oilseed residues:	Residues from the production of rapeseed and flax	
OR:	Oilseed raddish. Species used as model intermediate crop	
Potato residues:	Residues from both ware and starch potatoes	
Recommended IC harvest rate (%):	Suggested rate for the harvest of IC based on the capacity of IC cultivation to compensate for the loss of stable organic carbon inputs from residue removal	
Recommended residue removal rate (%):	Suggested rate for the removal of crop residues based on the capacity of IC cultivation to compensate for the loss of stable organic carbon inputs	
Removable:	Fraction of technical biomass that can be actually removed when considering other logistics affected by weather (assumed 80%)	
Root biomass:	Plant belowground biomass	
Shoot biomass:	Plant aboveground biomass	
Stable organic carbon:	Theoretical fraction of organic carbon in biomass that can be stabilized in the soil	
Technical potential:	Fraction of theoretical biomass available minus stubble (also know as harvestable potential)	
Theoretical potential:	For residues, all of the aboveground biomass produced as residual biomass	
SKO:	Yield survey district. Abbreviation of skördeområde in Swedish. For further information visit: https://jordbruksverket.se/om-jordbruksverket/jordbruksverkets-officiella-statistik/jordbruksverkets-statistikrapporter/statistik/2022-06-10-normskordar-2022#h-Kortomstatistiken
