Sorption versus mineralization of large organic N. Sorption after 1 h and mineralization after 14 days of large organic N (1–10 kDa organic fraction in light blue; > 100 kDa organic fraction in dark blue and red) in the Jyndevad soils (light and dark blue) at three pHCaCl2 levels: low at pH 3.6 (circle), medium at pH 5.4 (triangle down), and high at pH 7.1 (square), and for the largest organic N fraction also in the Askov soils (red) at three fertility levels: unfertilized (circle), NPK mineral fertilizer (triangle down), and animal manure (square) since 1894. Error bars are s.e.m. (n = 4).
