Abstract / Summary
This study evaluates how adding southern yellow pine-based biochar alters soil structure and hydro-physical properties in sandy-textured soil. Utilizing X-ray Computed Tomography (CT) scans on undisturbed soil cores, the authors tracked macropore variations at doses of 0, 7.5, 15, and 30 Mg per hectare. The findings reveal a dual mechanism: at lower application rates, biochar particles tend to occupy and block existing soil macropores (an "occupying effect"), whereas increasing the dose beyond 30 Mg per hectare begins expanding the soil＊s overall porous phase due to the biochar's inherent internal porosity.
