Cutting fertilizer use by a third and rotating tobacco with maize reshapes the fungal life living in soil, shifting which species dominate and how they function. The combination outperforms either practice alone, nudging soil fungi toward strategies that support nutrient cycling and plant health.
1
Reduced fertilization combined with tobacco-maize rotation produced a greater shift in fungal community composition than either practice applied alone.
2
The rotation-plus-reduced-fertilization treatment increased the proportion of fungi associated with nutrient cycling and decreased stress-tolerant, resource-exploitative guilds.
3
Fungal ecological strategies shifted from competitive/stress-tolerant profiles toward cooperative profiles linked to improved soil function.
