Also, modern hybrids have shorter stalks, and thus lay down less carbon

Not really, for the most part--hybrid wheat, corn, soybeans all are
essentially the same size plants as always. What crops specifically are
you thinking of?

Sorghum, wheat, barley, many of the varieties grown in Australia are
significantly less that 50cm tall at harvest, as opposed to heritage
pure strains many of which stand twice (or three times) as tall. Lots
of leaf, big seed heads, very little actual stalk.
