*In field experiments in x, biochar reduced nutrient leaching in [[Green roofs|green roofs]], but did not reduce nutrient concentrations in effluent (Kuoppamäki et al., 2016) <ref>Kuoppamäki, K., Hagner, M., Lehvävirta, S. & Setälä, H. 2016.

*In field experiments in Europe, biochar reduced nutrient leaching in [[Green roofs|green roofs]], but did not reduce nutrient concentrations in effluent (Kuoppamäki et al., 2016) <ref>Kuoppamäki, K., Hagner, M., Lehvävirta, S. & Setälä, H. 2016.

*No evidence was found of biochar being used for LID projects in Ontario yet. However, biochar is recommended on a trial/limited basis as a planting enhancement material for Toronto Green Streets (City of Toronto, 2017) <ref>City of Toronto. 2017. Toronto Green Streets Vegetation Selection Tool. https://www.toronto.ca/wp-content/uploads/2017/11/9844-2017_V-1.0_CoT-Green-Streets_Vegetation-Selection-Tool.xlsx</ref>. If you have used biochar in LID design, please let us know.
