It would make more sense to introduce seed priming and microdosing in areas
with low yield, even though the absolute yield increase is the same. The reason for
this is that the yield increase associated with seed priming and microdosing is less
visible at high yield levels, whereas the farmers can easily be convinced of the effect
in areas where the yields are low. The additional grain and corresponding straw
yield obtained under such marginal conditions may also be very valuable.
