Changes in soil organic carbon and nitrogen stocks in organic farming practice and abandoned tea plantation.

ABSTRACT:

Background

The restoration of conventional tea plantations and the adoption of organic farming practices could impact soil organic carbon (SOC) and nitrogen (N) stocks. This study investigated the soil properties, SOC and N contents and stocks, and their vertical distributions of a secondary forest restored from an abandoned conventional tea plantation and a converted organic tea plantation. An adjacent conventional tea plantation employing similar intermediate farming served as a comparison.

Results

Within a 50-cm depth, the secondary forest exhibited a higher SOC stock of 115.53 ± 7.23 Mg C ha^- 1 compared to 92.1 ± 8.54 Mg C ha^- 1 for the conventional tea plantation. No significant differences in N stocks were seen between the two land uses. Significa
