Variations of the total PLFA (gray wide bars), total bacterial PLFA (white narrow bars), gram negative bacteria (gray wide bars), gram positive bacteria (white narrow bars), fungi (gray wide bars) and eukaryotes (white narrow bars) under organic and inorganic phosphorus fertilizer amendments during 2016 (left) and 2017 (right). Error bars in each graph represents ± SE (n = 3). Different letters above bars indicate significant differences between organic and inorganic phosphorus sources at P < 0.05.
