Abstract

The paper presents an approach in tomographic instrumentation for agriculture based on dual-energy Compton scattering. The results show a linear relationship, independent of soil aggregate sizes with regression coefficient of better than 0.95 for bulk density and 0.70 for water content. A minimum detectable density of 0.13 g/cm³ and 0.10 cm³/cm³ were observed with better than 2% and 5% precision respectively. Compton scatter images of soil samples illustrating the efficacy of this imaging technique are presented
