I bought my last commercial compost, etc. a few years ago after it killed every plant that I used it on. I use manure from my goats, horse and chickens, old hay and grass clippings and such, no intentional chemicals used around here for years.
The issue that bothers me about GMO stuff is that it will not produce the same fruit/veggies the next year like heirloom seeds do. If it produces it will be stunted or irregular, etc..... Some will not produce a fruit/veggie period, only blooms.
This is because Monsanto can not make any money off of a seed/plant that we can save the seeds from and grow stronger better plants over the years (heirloom).
If Monsanto and other companies like them are allowed to have their way we will not have any plants/seeds that will produce a second time from the seed of that fruit/veggie...No money for them in that and they have no control over the people. It's all about the greed and love of money and control of the people. Greed, the love of money and control freaks is all they are and their all the same....
