Abstract

•	Biochar obtained from mixed paper fiber sludge and the grain husks resulted in a significant increase of SOC over 7 years.
•	Biochar aging resulted in a decrease in pH one year after its application in 2015 and 2019.
•	The combination of N-fertilizer with biochar caused an improvement in soil inorganic N content in 2014 and reapplication in 2018.
