Besides the abovementioned patterns, large differences in magnitudes
were found in variable nutrients (Table 2). For example,
nearly half of total SOM (48.42%), total N (47.35%), extractable N
(48.54%) were distributed in surface 20 cm soil, while relative less
percentage of total P (30.07%), extractable P (19.72%), total K
(20.08%) and extractable K (39.94%) were found in this layer
(Table 2).
