ion. The effective ratio is multiplied by 90% to estimate a single yield update factor which will be applied to the average yields on the farm for 2013 to 2017. In short, the yield update factor is the ratio indicating how much of the initial 90% of the 2013 to 2017 county average yields a farmer can claim in the update. For crops where the national average in 2008-2012 is close to the 2013 to 2017 national average, more of the maximum yield update (90% of 2013-2017 yields) can be captured.
