Shifts in soil nutrient concentrations and C:N:P stoichiometry during long-term natural vegetation restoration.

ABSTRACT:

Background

Ecological stoichiometry (C:N:P ratios) in soil is an important indicator of the elemental balance in ecological interactions and processes. Long-term natural vegetation plays an important role in the accumulation and distribution of soil stoichiometry. However, information about the effects of long-term secondary forest succession on soil stoichiometry along a deep soil profile is still limited.

Methods

We selected Ziwuling secondary succession forest developed from farmland as the study area, investigated the concentrations and stoichiometry of soil organic carbon (SOC), total nitrogen (TN), and total phosphorus (TP) at a depth of 0-100 cm along a 90-year succession chronosequence, including farmland (control), grassland, shrub, early forest, and climax forest.<
