Regardless to popular belief, corn is not a good crop for surviving a SHTF Doomsday event.
When the topic of food crops for SHTF comes up in the forum, there is one that is talked about more than others, and that is corn. There is a common misconception that all someone needs to do to grow corn is to plant the three sisters – beans, squash and corn.
In theory, the beans are supposed to supply the corn with much needed nitrogen. While beans and peas produce their own nitrogen, it is not in a form that can be easily used by other crops. In other words, there is more to growing corn than just planting beans with it.
Then there are the various types of corn. Corn seed we get from the local farm supply store is a far cry from native corn grown by indigenous Native American tribes.
