kellyrox is helpful, nice and has lots of friends here
Talking info needed

My name is Kelly and I am going into 8th grade GT Science. I am testing which plant is the best buffer for nitrogen and phosphorous runoff. I know that I am going to have to make a model that has plants at the top of a hill and a "river" at the bottom. The fertilizer would become run off after a "rain" and then I would use nitrogen and posphorous testing kits to test the water. So that's the basics of my plan. I want to know if you could help me find places that give information to help me with this. Any help would be greatly appreciated.

you should know why the runoff is bad. Have you researched that?

Also, have you made sure that everything in your experiments is constant?

Also, lovely experiment!
