Protist communities are more sensitive to nitrogen fertilization than other microorganisms in diverse agricultural soils

Table 1 The effects of soil type, season, and fertilization treatment on the differentiations of soil physicochemical properties and bacterial, fungal, and protist communities based on PERMANOVA
