Dono, what is the 'secret sauce' to maintain a bloom so consistently? My pond may hold a bloom for 2 weeks in the spring and sometimes a bit in late fall but I never dared toy with fertilizer as I feared fighting more FA or other unwanted weed explosions.
Some fertilizer runoff from my front yard which slopes to the pond I believe starts the first bloom but I try to teach the crew that throws the fertilizer to try to avoid the pond area.
Our pond is topped up with a drainage ditch next to it. The drain has about 300 acre of farm land that is systematically tiled every 20 feet. The pond is fertilized basically all year from the farm land. The only problem with this is atrazine. When there is a large rain event the fill pump gets turned off.
A good part of this could be sediment and not 100% a plankton bloom. All I know is visibility has never been clear any more then 3 feet in the winter.
Guess they are trying to ban atrazine in Canada for use on crop land. Will have to see.
Cheers Don.
EDIT: added a picture from google maps. You can see the drain next to the pond.
