“…Moreover, a scaling challenge ex ists in distributing SC, a Critical Zone property that is highly heterogeneous in nature, across the landscape. To address this challenge, many environmen tal parameters have been used to describe SC distribution using statistical ap proaches (Arrouays et al, 1998;Jobbágy and Jackson, 2000;Kulmatiski et al, 2004;GarciaPausas et al, 2007;Hirmas et al, 2010;Kunkel et al, 2011), yet these approaches are limited because they often use surrogates for the soil en vironment (precipitation, topography, etc.) rather than actual soil environment variables (soil water content, temperature, or net water flux), and they are not necessarily transferable and grounded in processbased understanding.…”

“…These organic materials comprise the stock of soil organic carbon (SOC), whereas carbonates primarily represent the stock of soil inorganic carbon (SIC) [3]. Through dynamic processes, there is a relationship between soil carbon (C) and atmosphere C; therefore, soil can partly buffer rising atmospheric CO 2 concentrations [4].…”

Paddy soils are classified as wetlands which play a vital role in climatic change and food production. Soil carbon (C), especially soil organic C (SOC), in paddy soils has been received considerable attention as of recent. However, considerably less attention has been given to soil inorganic carbon (SIC) in paddy soils and the relationship between SOC and SIC at interface between soil and the atmosphere. The objective of this research was to investigate the utility of applying Fourier transform mid-infrared photoacoustic spectroscopy (FTIR-PAS) to explore SOC and SIC present near the surface (0–10 µm) of paddy soils. The FTIR-PAS spectra revealed an unique absorption region in the wavenumber range of 1,350–1,500 cm−1 that was dominated by C-O (carbonate) and C-H bending vibrations (organic materials), and these vibrations were used to represented SIC and SOC, respectively. A circular distribution between SIC and SOC on the surface of paddy soils was determined using principal component analysis (PCA), and the distribution showed no significant relationship with the age of paddy soil. However, SIC and SOC were negatively correlated, and higher SIC content was observed near the soil surface. This relationship suggests that SIC in soil surface plays important roles in the soil C dynamics.
