KPIid,KPIvariable,Description
A1,Yield per crop,observed yield (user input)
B1,Nitrogen surplus,Nitrogen surplus = N artifical fertilizer + N manure+ N atmospheric deposition + N fixation by crop - N removal through harvested product. Calculated KPI internal model & parameters and from user input: yield and fertilizer/manure applications. N fixation  (legumes only): internal equations. N depostition: RIVM maps
B2,Phosphate surplus,Phosphate surplus = P fertilizer  - P removal through harvested product. Calculated KPI internal model & parameters and from user input: yield and fertilizer applications 
C1,Effective OM supply,"Organic matter surplus = Organic matter from manure + Crop residues to soil - organic matter removal through harvested product. Calculated KPI internal model & parameters and from user input: yield and manure applications. ""Effective"" means netto, after correction for carbon respiration by soil microbial activity"
D1,pesticides,"kg/ha of active ingredient. Sum over kg a.i.  of the different crop protection agents applied, with concentration (kg a.i. / kg or litre) of  crop protection agents retrieved from CTBG"
E1,mbp,"milieubelastingspunten. 3 Quantitative sub items & 2 Qualitative (A, B, C)"
F1,greenness,?
F2,rotationindex,farmlevel index of diversity of crops
,KPItargetvalue,target value as in benchmark value for same crop in same region. E.g. cropyield target is from Central Bureau of Statistics (CBS) for same crop in region in which the cropfield (geometry) is located
,KPIthresholdValue,threshold from ??? Ask farmmaps. Surplus nitrogen / phosphate / pesticides must not be above threshold. Surplus organic matter supply must be above threshold
,totalNapplied,"Not a KPI output, simply calculated from the input operations with their respective ""n"" in their ""data"""
