 Independence Day is about freedom. What this means for your crop is that no one's telling you what you have to do. You're free to fertilize, till, spray, or almost anything else you want to do, for the most part. Well, here's the challenge with that. There are lots of options today. There are literally hundreds of things you can spray on your crop. There are dozens of soil testing and tissue testing labs that will likely all give you slightly different results. Same thing with thousands of crop advisors out there.
