Mark,

I'm surprised your not growing tired of this exchange--I'm sure everyone else has.

Before my research on the net and Pondboss days, I lost lots of fish due to dairy cows. Now I have diverted most of the water ( some goes in on the bigger rains ) and am running in a small stream from a well. The nutrients are still there which is why backbreaking removal of moss isn't so bad. I throw it way up on the bank.

Without flushing rains, will those nutrients always be there or will they layer under mud and eventualy be gone?
