Table 2 The summary of mean separation analysis for soil organic matter (OC) and mineral nitrogen (MN) content distributions at 0.10 m depth increments and for their pools (totals) in soil profiles along the four transects to determine whether these were impacted by different land-use practices and/or the physical location of the transects in the farm. During the experimental design stage, two out of the four transects were considered as replicates for the 3-year-old reforested riparian (RR) and the corresponding cropland (CP) and bare riparian (BR) land-uses and the other two transects as replicates for the 6-year-old RR, CP and BR land-uses

  1. Same block letter(s) in a given row or small letter(s) in a given column indicate the means are not significantly different at P < 0.05. The 3-year-old RR along one out of the four transects is abbreviated as 3 yr-reforested riparian-1, and the corresponding CP as 3 yr-cropland-1 and the BR as 3 yr-bare riparian-1. Similar abbreviations; 3 yr-reforested riparian-2, 3 yr-cropland-2, 3 yr-bare riparian-2 are used for the second 3-year-old RR, the corresponding CP and BR land-uses along the second transect. The abbreviations for the two 6-year-old RR and the corresponding CP and BR land-use practices along the other two transects are similar to what has been used for the 3-year-old RR transects land-uses
