Dissolved organic matter in soils varies across a chronosequence of Pinus massoniana plantations

Stand age plays a significant role in forest ecosystems nutrient cycling. Unfortunately, less attention was accorded to the changes in dissolved organic matter (DOM) in soil layers of mono‐stand plantations. A field soil sampling experiment was conducted to examine the effects of forest age and soil...

Description
Summary:Stand age plays a significant role in forest ecosystems nutrient cycling. Unfortunately, less attention was accorded to the changes in dissolved organic matter (DOM) in soil layers of mono‐stand plantations. A field soil sampling experiment was conducted to examine the effects of forest age and soil depth on concentrations and distribution patterns of dissolved organic carbon (DOC) and dissolved organic nitrogen (DON) in a chronosequence of 11 stands of Masson pine (Pinus massoniana) plantations. The soil total organic carbon (TOC) and soil total nitrogen (TN) were also investigated. Concentrations of DOC and DON varied with stand age and decreased significantly (P
