Overall effectiveness category No evidence found (no assessment)
Number of studies: 0
Background information and definitions
This action involves adding chemicals – such as lime (CaO or Ca(OH)2), limestone (CaCO3), magnesium oxide (MgO), fly ash (residue from burning coal) and biochar (a type of charcoal) – to areas planted with marsh or swamp vegetation. These calcium and/or magnesium-rich chemicals may reduce acidity and modify nutrient availability (Weil & Brady 2016), potentially increasing plant survival or growth.
Related actions: Add lime or similar chemicals to wetlands, other than to complement planting.
