A letter in the Irish Times (arguably the only "quality" Newspaper in Ireland) today is from a farmer up-country, who claims to have succesfully cured an algae bloom in a pond by submerging a "large bale of hay" in the water. Has anybody out there ever heard of such a "cure"? I cannot think how the presence of the hay bale could affect the pond's ecosystem ... if anything I would think it would add to eutrophication?
Is it all a wind-up, or is there anything in it? (The same correspondent also claims that Lion Dung (obtained from Dublin Zoo!) spread around the perimeter of his farm has succesfully controlled/discouraged the local fox population from using his land and lambs as a resource! ... and he also says that Elephant dung from the same source is wonderful for growing roses! Any of you near a zoo might like to try it.....?)
