TY - T1 - Nitrogen Recovery from Clear‑Cut Forest Runoff Using Biochar: Adsorption–Desorption Dynamics Affected by Water Nitrogen Concentration SN - / UR - http://hdl.handle.net/10138/335193 T3 - A1 - Kakaei Lafdani, Elham; Laurén, Ari; Cvetkovic, Jovana; Pumpanen, Jukka; Saarela, Taija; Palviainen, Marjo A2 - PB - Y1 - 2021 LA - eng AB - Forest regeneration operations increase the concentration of nitrogen (N) in watercourses especially outside the growing season when traditional biological water protection methods are inefficient. Biochar adsorption-based water treatment could be a solution for nutrient retention. We studied the total nitrogen (TN) and nitrate-nitrogen (NO3--N) adsorption-desorption properties of spruce and birch biochar. The adsorption test was performed under four different initial concentrations of TN (1, 2,...
