Table 2 Weight of particulate organic matter (POM 4000–50 μm) fractions at year 5 of the second rotation (R2Y5)

From: Soil organic matter quality along rotations in acacia and eucalypt plantations in the Congolese coastal plains

POM fraction weight /Stands 100A 50A50E 100E
After fractionation of 20 g of soil:
 cPOM 0.14 (± 0.01) a 0.18 (± 0.01) a 0.19 (± 0.03) a
 fPOM 0.35 (± 0.02) a 0.39 (± 0.02) a 0.40 (± 0.03) a
 OMF 2.01 (± 0.06) a 1.61 (± 0.17) a 1.81 (± 0.07) a
In g per kg of soil:
 cPOM 6.87 (± 0.52) a 8.93 (± 0.47) a 9.47 (± 1.42) a
 fPOM 17.71 (± 1.01) a 19.53 (± 0.28) a 19.77 (± 1.42) a
 OMF 100.7 (± 3.2) a 88.7 (± 1.6) a 90.3 (± 3.7) a
  1. 100A and 100E = pure acacia and eucalypt, respectively, while 50A50E = mixed-species (50% acacia and 50% eucalypt) stands. cPOM = coarse POM (4000–250 μm), fPOM = fine POM (250–50 μm) and OMF = organo-mineral fractions (< 50 μm). Different letters indicate significant differences at P = 0.05 between stand types at R2Y5
