Abstract

There is an error in the fourth sentence of the Abstract. The correct sentence is: Our results showed that the soil N and P concentrations and the N: P ratios varied from 0.15 g kg−1 to 0.56 g kg−1 (average of 0.31 g kg−1), from 0.09 g kg−1 to 0.16 g kg−1 (average of 0.12 g kg−1), and from 2.42 to 4.36 (average of 3.42), respectively; additionally, values significantly and linearly decreased with soil depth.
