Nadine –
I am not certain if the cottonseed meal we offer is GMO-free and have forwarded your question to the mill to get an answer. I will post their response as soon as I hear something.
As for how cottonseed meal containing GMOs will effect your gardenโฆ The answer is: I donโt know. In the search for answers, I contacted a handful of experts who study horticulture at major universities and those that replied said pretty much the same thing. They couldnโt comment because theyโre just wasnโt enough, or any, research. One of the more distinguished professors we asked hazarded a guess: that the act of decomposition would probably take care of any genetically manufactured plant material and would most likely break down any by product it produced. But he couldnโt say for sure.
