Fig. 1From: Response of soil biological properties and bacterial diversity to different levels of nitrogen application in sugarcane fieldsCompositions of soil bacterial communities at phylum level 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
