<Summary>For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.881158"! ** Cumulative release of nitrate during repeated extractions with 2 M KCl of three contrasting biochars after: 
(1) soaking 1:10 (w/v) in 19.4 mMol NH4NO3 solution at 22±3°C for 72 h 
(2) soaking 1:10 (w/v) in 19.4 mMol NH4NO3 solution at 65±1°C for 72 h 
(3) manual picking from mature compost after biochar co-composting with mixed manures as described in doi:10.1371/journal.pone.0171214.
