At home, I do the basic weed/feed and such for a descent lawn. It looks real nice but honestly I dont want to spend the extra money or time to make it really nice, I have too many summer hobbies for that. At our lakehouse, we do not use much, mostly sand. We really try to keep stuff (nitrates, phosphates, general runoff) out of the lake. A cranberry farm (marsh) on our lake (and I worked there for 5 summers, loved it) closed and they allowed it to go back to a natural wetland. And I can tell you, the quality of water in the lake has increased significantly. The clarity has increased significantly and the late season algae blooms have decreased also. We dont get the nasty eutrophic water conditions that we used to....hence think Rice Lake, even woth low and warm water conditions.
