Effects of soil water and phosphorus contents on the spatial distributions of cotton root length (a) and hyphal density (b). Data at the top of each diagram correspond to the total cotton root length (a) and mean hyphal density (b) in the root boxes. Different letters indicate significant differences at the 0.05 level among different treatments. a Data on the right side of each diagram represent the cotton root length (m) in each soil layer (10 cm layer) and the ratio (%) to the total root length. b Data on the right side of each diagram correspond to the average hyphal density (m g− 1) in different soil layers. Data are presented as the mean values over 2 years (2015 and 2016) (same as in the other figures)
