Soil Core Samplers - Soil Samplers - Hand Tooling

Temperature sensitivity ( Q 10) of soil organic matter (SOM) decomposition is a crucial parameter for predicting the fate of soil carbon (C) under global warming. However, our understanding of its regulatory mechanisms remains inadequate, which constrains its accurate parameterization in Earth system models and induces large uncertainties in predicting terrestrial C-climate feedback.

Soil Sampling - an overview | ScienceDirect Topics

In the conventional soil core-sampling (COR) method (control), soil samples were collected using soil core samplers (COR) with a known volume. The soil was sampled with a metal cylinder with dimensions of 0.074 m in diameter and 0.1 m long, resulting in a volume of 0.00043 m 3 . Roots were extracted from the soil by washing with tap water ...
