A perennial grain is quite a revolution! I assume it would likely still be a monoculture in practise but leaving roots in the ground year round instead of tilling is going to do wonders for the soil life and structure.

I'm really excited to see that it's progressing! In particular, it is now possible to actually buy seed, which is a major development. Looking closer, however, you do need to apply and be licensed to do so. Found this to be interesting: https://kernza.org/wp-content/uploads/Obtaining-Seed-and-Becoming-a-Kernza-Grower-May-2022.pdf
Main takeaway; weeds are a problem, yields comparatively low. Royalties of $5/acre seems reasonable, assuming the seed is not massively expensive, and it actually takes & the plants live long enough. Wish I had the equipment & space to give it a try!
