Fig. 5From: Response of soil biological properties and bacterial diversity to different levels of nitrogen application in sugarcane fieldsPrincipal component analysis of the relative abundance of soil bacteria at the OTU level in sugarcane fields under four N application treatments. H: high N application in the sugarcane soil (964 kg ha−1), M: medium N application in the sugarcane soil (482 kg ha−1), L: low N application in the sugarcane soil (96 kg ha−1), CK: no N application in the sugarcane soil (0 kg ha−1)Back to article page
