Legume leys + boreal agroforestry: plant-level mechanisms behind Finland’s 13.9% organic acreage

Conflict of interest: I’m the author. It’s a science-first essay on how Finland’s organic fields hold up in a cold, short-season context: legume–grass leys, legume–cereal rotations, and boreal hedgerow/agroforestry edges. I summarie effects on N fixation, nitrate leaching, soil-C formation, and rotation disease pressure.
I’d value critique on three points:

1. Where do I overgeneralize?
2. Open-access sources on AMF/ley effects in boreal mineral soils?
3. Any data on light (PPFD) and yield vs. hedgerow spacing in temperate/boreal systems? (Open access; clean link, no tracking.)

I asked feedback from my university connections regarding organic farming, which I did a side study on, and they were all positive, there is just so little experience related to AF in here ( It is non existing almost)
