Aquatic Weed Harvester Debuts on Hummock Pond
The first step in an effort to rid Hummock Pond of excessive aquatic vegetation went off without a hitch, with around 23,000 pounds being pulled from the 160-acre pond with the help of a machine called an aquatic harvester.

The build-up of vegetation, including sago pondweed, redhead, coontail weed, fennel and filamentous algae, is the result of decades of nutrient overloading which is affecting water quality and threatening the natural habitat for species that live and breed in the pond.

Once out of the water, the vegetation was transported to a local farm where it will be used as fertilizer. Farm owner, Josh Bartlett is a visionary who believes that uses the nutrient laden aquatic plants will put the nutrients where they belong, on his fields rather than having to rely adding more chemicals to the soil.

Robert Williams, founder and director of Nantucket Pond Coalition, thinks this pilot program on Hummock Pond proved that a regular harvesting effort will be beneficial with regards to conservation efforts.

Verona New Jersey to go Phosphate-Free? - Phosphates enter waterways from human and animal waste, phosphorus rich bedrock, laundry, cleaning, industrial effluents, and fertilizer runoff. These phosphates become detrimental when they over fertilize aquatic plants and cause stepped up eutrophication. If too much phosphate is present in the water the algae and weeds will grow rapidly, may choke the waterway, and use up large amounts of precious oxygen (in the absence of photosynthesis and as the algae and plants die and are consumed by aerobic bacteria.) The result may be the death of many fish and aquatic organisms.
