文摘
- •
A novel field N manipulation experiment with both UAN and CAN was established.
- •
N addition reduced pH, BS and Ca and increased Al at temperate forest.
- •
N addition reduced biomasses of most soil microbial groups at subtropical forest.
- •
Effects of CAN on forest soils were not significantly different from that of UAN.
- •
No interactions between N treatment approach and study site or N addition rate.
