Redistribution of soil phosphorus fractions alleviates phosphorus limitations following afforestation

Afforestation plays a crucial role in mitigating climate change, yet the transfer of soil phosphorus (P) to aboveground biomass may lead to soil P limitation. However, the influences of afforestation on soil P fractions and availability remain unclear. Here, we investigated soil P fractions at 144 paired sampling sites by comparing afforested lands with adjacent non-afforested lands in subtropical China.
