Calculation error - Crops: CO2 emissions from urea are underestimated by 3-6% with use of UAN

When using urea ammonium nitrate solution as fertiliser, the Cool Farm Tool uses 35% urea rather than 50%, which means that CO2 emissions are underestimated by between 3 and 6%.

This will be fixed as part of the migration to the new Cool Farm Platform.
