To those who dont know, sorghum and millet are the poor man’s corn, very difficult to process into a digestible (eatable) form. Sorghum and millet were considered in my time as forrage, animal feed, unfit for human consumption.
Interesting perspective, from a water engineer, no less. Of course, one of the advantages of sorghum and millet might be that they don’t need water engineers quite as much as corn.
