Table 3 The summary for the simple linear correlation analysis performed between the mean soil attribute content in a given profile section and the corresponding profile depth to determine whether the distributions are impacted by land-use practices

From: Characterizing selected soil attributes of different land-use management to assess reforestation benefits of deforested riparian buffers

  1. The correlations are significant at P < 0.05. They were carried out using the means listed in Table 2. The correlation for the two 3-year-old reforested riparian (RR) land-use is abbreviated as 3 yr-reforested riparian, the corresponding cropland as 3 yr-cropland (CP), and the bare riparian as 3 yr-bare riparian (BR) in this table. Similar abbreviations are used for the 6-year-old RR and the corresponding CP and BR land-use practices
