Approved Regenerating Calculations
Photosynthesis
Average Trend against Region Trend last 10 years Change against trend
-0.03 -0.01 0.02
Trend must be positive with 1 possible down year
Soil cover
Average Trend against Region Trend last 10 years Change against trend
-0.03 -0.01 0.02
Value must be positive against trend
Change in Soil vitality
SOC% SOC% change as factor (change as factor: 3.3%/3%= 1.1)
SOCt SOCt change (change as factor: 1100t/1000t= 1.1)
pH closer to optimum or reasoning why ok (Factor change from category lowest, low, optimum, high, highest in % of pixels - f.e. 1.03)
P closer to optimum or reasoning why ok (Factor change from category lowest, low, optimum, high, highest in % of pixels - f.e. 1.03)
K closer to optimum or reasoning why ok (Factor change from category lowest, low, optimum, high, highest in % of pixels - f.e. 1.03)
P:K ratio better or best (1:2-1:4 as optimal)
K and P:K ratio might be different per country. F.e. in Brazil they get replaced by CEC and AL3+
Total Sum of all factors divided by number of factors
Value must be positive against trend

Water m3 change as factor 0.68 to previous year or if available 3 years average
Crop Protection € change as factor 0.68 to previous year or if available 3 years average
Animals LSU/ha Optimum =1-1,5, gradual change from 0-1 and 1,5-2,5 Min 0 and max 2.5
Nutrient Efficiency Change factor change as factor Changefactor average for MJ, N, P, K divided by change factor N, P, K of current vs. Previous year or if available against 3 years average
Total Sum of all factors divided by number of factors
Change in Yield factor / Efficiency factor should be 1 or higher
Value must be positive against trend
