Stoichiometry Characteristics of C, N, and P of Soil Profiles along an Altitude Gradient in Luofu Mountain, Guangdong

Abstract

The vertical distribution and stoichiometry characteristics of soil organic carbon (SOC), total nitrogen (TN), total phosphorus (TP) of soil profiles along an altitude gradient were investigated in Luofu Mountain, Guangdong. A total of ten sites at different altitude gradients in Luofu Mountain were selected and soil genetic horizon samples were collected. Soil physic-chemical properties, such as bulk density, soil particle-size composition, pH, SOC, TN, TP, total iron oxides (Fe t ), free iron oxides (Fe d ), amorphous iron oxides(Fe o ), CEC, etc, were
