Biochar Classifications
Product reference for four particle grades (Medium, Small, Powder, Dust) with mesh sizes and recommended applications. Paper-clip photos for scale.
Research
Evidence for high-quality biochar
Technical summaries and partner research that support water holding, nutrient adsorption, turf performance, and water-quality applications. Additional materials will be added as they are cleared for public use.
Featured resources
Reports & technical summaries
The materials below include Georgia Wood Char product references (particle grades and golf/turf) plus Biochar Now published research (used with permission under our license relationship) and independent lake-management evaluations that examined biochar filter performance.
Biochar for Golf Courses
Turf & water solutions brief: cleaner ponds, irrigation efficiency / water conservation, and stewardship benefits for golf course managers.
Golf & Turf Biochar Study: Results Summary
Up to 50% water savings, 5.6× water-holding capacity, nutrient holding backed by independent lab tests, and top-dress application for greens and fairways. Study source: Biochar Now golf & turf program summary.
Brooks Lake 2023 Biochar Efficacy Evaluation
Field evidence of biochar cleaning lake water: 445 biochar filters on docks and boatlifts, with early drops in dissolved solids, ammonia and chlorophyll-a. Independent report by Restorative Lake Sciences, November 2023.
Silver Lake 2023 Report with Biochar Efficacy Results
Field evidence of biochar filtering runoff: filters in five drains and on docks and boats cut total phosphorus and suspended solids, capturing about 1.4 tons of phosphorus in the 2023 season. Independent report by Restorative Lake Sciences, November 2023.
Nutrient adsorption — independent lab summary
Tabulated results for phosphorus (up to 99.8–99.9%), phosphate, ammonia, and nitrate adsorption from water using Biochar Now material. Water holding capacity stated at 5.6 × biochar weight.
Library note
Grades, photos, and what we can share next
Particle grades and scale photos are on the site now — see Products, the Biochar Classifications PDF above, and Buying from Georgia Wood Char for how to quote. Use those for specs and bids when mesh size and application matter.
We’re still clearing additional white papers, trial data, and application notes for public use. If you need a study that isn’t linked here yet, contact sales and we’ll prioritize what we can share.
Source credit: Core process research and many performance datasets originate with Biochar Now and are used under license and with permission. Lake reports are independent work by Restorative Lake Sciences. Always cite original authors when using these materials externally.
