Pond Boss Forums POND CONSTRUCTION Soil questions How to get grass established on clay?

Question guys..
You can see from my October pics, that the grass and wheat came up last fall.
I'm thinking of dumping a bit more seed down.
The question is; will I do something awful to the water if I also throw down some fertilizer on the new grass and seed? I was going to put down lime also.
Im not talking about a lot of fertilizer, but maybe a light broadcast of some starter type for lawns.
I just figure the stronger I can get this new grass, the better it's going to hold up in filtering the incoming water and stabilizing the banks.
I suspect when the guys farming the two alfalfa fields spray fertilizer this spring, some of that will end up in the pond also.
I'm getting ready to put in fish, I don't want to mess up the water..
Thanks,
Jeff
