A regular comment I hear from my Ukrainian farming colleagues is "...that's all well and good in Europe but here in Ukraine the soil/sun/rain/snow is different so it won't work here!"
Distilled down to its essence, crop farming is the act of putting seed in the ground, nurturing it and harvesting the results.
Doesn't matter where in the world you are, that's it.
What changes is the timing of putting the seed in the ground and the nurturing and the harvesting but the fundamental act remains the same.
To that end I noticed that poppies are now in full flower in Ukraine as they are in England which suggests that any difference between timing is actually very small.
Which to my mind suggests that modern farming practices and techniques are equally valid in Ukraine as in Europe and America and Ukraine is not some special place that only local agronomists know how to farm.
Remind me again what average yields are in Ukraine?
