Biochar

Safely Filter Excess Pond Nutrients

Biochar - SOLitude Lake Management

Aquatic ecosystems are constantly changing due to the surrounding environment. Excess nutrients from runoff, vegetation, wildlife and humans enter the water column and can negatively impact a waterbody's health. These foreign nutrient sources inevitably lead to poor water clarity, algae blooms, foul odors and fish kills. Proactively preventing these water quality issues can be naturally achieved with the latest technology in nutrient management: biochar

What is biochar? It's a is a highly adsorbent material very similar to activated charcoal; activated charcoal is derived from coal, while biochar is derived from wood. Biochar has been traditionally used to improve soil fertility and agricultural yields, but can also be utilized as a natural nutrient management tool in lakes and ponds. Contained in a large sock-like bag, this porous material allows water to flow through while pulling nutrients, metals and pollutants from the water. Placing the bags near inlets or in moving water will yield the best results. Once the bag is full, it is pulled from the water which physically removes the pollutants from the water column. The material can be disposed of or even placed in gardens to aid in fertilization. 

Biochar - Nutrient ManagementLakes and ponds with moving water are excellent candidates because the flow will naturally circulate nutrients for absorption by the socks. Waterbodies without water movement would benefit from pairing biochar with the installation of a fountain or diffused aeration system to achieve faster and more consistent results. The number of bags installed in a waterbody and the frequency in which they are replaced with new ones depends largely on water quality and waterbody size. A larger lake may require more biochar socks than your backyard pond, but depending on present nutrient levels, they can last for six months or more. Ultimately, custom water quality tests are necessary to make more exact determinations about the number of socks needed and the rate at which they should be replaced. 

This natural management method offers a new, safer way to filter unwanted nutrients and pollutants that feed algae blooms and other aquatic nuisances. Creating a nutrient management plan is the foundation to a healthy and sustainable ecosystem. Might your lake or pond be a good candidate? Our freshwater management experts are prepared to analyze your waterbody and create a custom biochar solution that will restore your aquatic ecosystem.
