i put a pic up...
its a pipe capped off on both ends...
staked to the ground on 1 end...
it has holes on the top of the pipe so a lil bit( 1 kernel at a time, probably 1/2" hole,) of corn can get out at a time when the hogs throw it..
the hogs will throw this thing in circles, clearing out an area, for a food plot..
remember to have the seed, cause when ya move the pipe to the next area, ya want your plot to grow up instead of weeds in the new tilled area..

ps..your ph test is going off the type of seed you are putting down..if your plantin bushes vs plot, the ph requirements are (could be) different..why your getting conflicting ph results.
