showed a trendno p-value reported
( 2021 ) found that in Populus alba plantations, the diversity index of soil fungal communities showed a trend of first increasing and then decreasing with forest age (4a, 9a, 15a, 25a, and 30a), with available phosphorus and nitrate nitrogen being significant influencing factors.
