MovingFloating Islands for Lake and Pond Management

December 15, 2018by was73100

Managing unwanted aquatic plant growth (pond weeds) in a lake or pond usually boils down to reducing and managing the amount of organic nutrients contained in the water. Herbicides give quick results but the effects do not last long because the root cause remains while only the symptom of heavy growth was temporarily diminished. The typical watershed includes manicured urban lawns and agricultural land actively in use. Urban lawns have pesticides and fertilizers applied to them at ever increasing levels as people chase the idea of a lush lawn the perfect shade of green. The relatively short and shallow rooted turf grass cannot absorb all the nutrients from the fertilizer and does nothing to hold back sediments as rain easily flushes both downstream into the pond. Agricultural land also has fertilizer use but at a very controlled rate as the farmer only wants to spend enough money to get the amount needed to the crops. A few feet below the surface lies a tile used to keep the land dry enough to use large equipment on to plant, maintain and then harvest those plants. In the short distance from the surface to the tile not all of the nutrients can be cleared. Once the water hits the tile, no more nutrients are removed as the water is transported to the nearest stream and pond. All of this leads to nutrient rich ponds with ever increasing levels of aquatic plant growth.

There are techniques to reduce and control the nutrients in the lake and pond and the best use nature to do the work. Floating islands are a manufactured platform that floats on the surface of the water supporting native wetland plants and natural bacteria which both digest and sequester nitrates and phosphates in the water that other aquatic plants use to grow. Getting this natural system is easy and quick. The islands come with preformed areas the size of a small pot that are filled with a small bit of soil and a plant plug bought locally. Wetland plants native to your area are best as they are adept at surviving the local conditions and contribute to the natural environment. The small amount of soil in the preformed pots give the young plant plugs a jump start to get growing.

As the wetland plants continue to grow, the roots extend into and then through the matrix of the island hanging out the bottom in the water. The roots then pull everything they need from the water column which includes the nutrients nitrates and phosphates. Natural bacteria already growing in the water and bottom composition of the pond take advantage of the island to grow…
