TABLE 4.

P-value of Adonis test of Bray–Curtis dissimilarity matrix across crop sequence treatments within each season.

Treatment	Spring15	Mid15	Fall15	Spring16	Mid16	Fall16
All crop sequencesa	< 0.001***	< 0.0001***	< 0.001***	< 0.001***	< 0.001***	< 0.001***
Soy vs. Corn	0.45	< 0.001***	< 0.001***	0.44	< 0.001***	< 0.001***
Soy only	< 0.001***	0.04∗	0.01∗	< 0.001***	0.04∗	0.07.
Corn only	0.13	0.5	0.24	0.02∗	0.29	0.44

^aAll crop sequences included comparison across all 10 crop sequences; soy vs. corn compared between all pooled treatments from each different crop; soy/corn only compared among crop sequences with different number of years of monoculture of soybean or corn grown in each year. Significant differences are reported at FDR corrected (^∗) P < 0.05, (^∗∗) P < 0.01, and (^∗∗∗) P < 0.001.
