Kind of a different question here...
First of all , our home has underground sprinklers on about 1 acre of grass. In order for the pump to keep up to the water demand when they are on the sprinklers are on a manifold system.
My question is this.. is there a way a person could attach a tank to the underground sprinkler line and then fill it with liquid fertilizer so it sprayed a combination of water and fertilizer? Is there a gadget that has been invented to do this? Saves me having to wander around the yard with a broadcaster every year. Thanks for any suggestions.... Jim
