I will be transparent with you. I work in research for one of the big ag companies. We are spending billions a year on R&D. A lot of it to come up with products that can adapt to climate change. We wouldn’t have the money to spend on that if farmers kept their seed and planted it. Public lines are being developed for people to buy and replant but the rate at which those come out is significantly slower because there isn’t the money to spend on R&D. That comes from grants and university funds
I am constantly amazed at the gains seed companies have made with drought resistance and just increasing yields in general. My only real complaint is that the seed dealers seem to be the ones making money in my area. More than any of the small to medium farmers. To me, they make way too much given the job they actually do.
