While the weather is cold and I have the time, I would like to build something to lay a line of fertilizer by the corn in a line, one row at a time. I can use either my tractor or atv to do it. I don't want to spread fertilizer, I did that last year and grew the biggest healthiest weeds you ever saw. I envision a pipe to the ground and a hopper of some kind, but how it would feed stumps me. Any help would be appreciated.
