I’m going to spread 200 pounds of phosphorus binder to my 3.5 acre pond. The label says to mix a slurry and distribute evenly around the pound edges.

How does one distribute that slurry? I have a tractor and a 50 gallon sprayer but I’m not sure if the slurry will just clog the pump and/or the sprayer nozzle. I also can not access about half the shoreline due to the topography.

I’m wondering if I really need to make a slurry before putting it into the water. I was hoping to motor around in my boat and simply spread the powder across the surface by hand. It seems like making a slurry is just an unnecessary step.

If it matters, the pond has an aeration system with three bottom diffusers.
