Application of x-ray computed tomography in the evaluation of soil porosity in soil management systems

Blog Article

The study aimed to evaluate a methodology to quantify the porosity of the soil using computed tomography in areas under no-tillage, conventional tillage and native forest.Three soil management systems were selected for the study: forest, conventional tillage and no-tillage.In each soil management system, undisturbed soil Rehab samples were collected in the surface layer (0.0 to 0.10 m).

The tomographic images were obtained using a X-ray microtomography.After obtaining the images, they were processed, and a methodology was evaluated for image conversion into numerical values.The statistical method which provided the greatest accuracy was the percentile method.The methodology used to analyze the tomographic image Neff B87VS38N0B N 90 Slide allowed quantifying the porosity of the soil under different soil management.The method enabled the characterization of soil porosity in a non-evasive and non-destructive way.
