Value of p for alpha diversity metrics comparing inoculum concentration and mineral fertilization levels: observed richness, Shannon index, Simpson index and Chao1 index.

Indices	Observed richness	Shannon	Simpson	Chao1
Inoculum	0.342	0.195	0.419	0.342
Fertilization	5.19 × 10−5***	2.95 × 10−7***	2.59e−07***	5.44 × 10−5***
Inoculum × Fertilization	0.671	0.545	0.367	0.674

Three asterisks ^*** indicate statistical difference p < 0.01.
