Contrasting effects of N addition on the N and P status of understory vegetation in plantations of sapling and mature<i>Larix principis-rupprechtii</i>

Abstract

The productivity of forest plantations in temperate areas is often limited by nitrogen (N), but may shift towards phosphorus (P) limitation with increasing atmospheric N deposition. Nutrient resorption is a nutrient conservation strategy in plants. Although data on nutrient resorption are available for overstory trees, there are few data for understory vegetation.
