Development of a Real-Time Measurement System for Horizontal Soil Strength

Abstract: Purpose: Accurate monitoring of soil strength is a key technology applicable to various precision agricultural practices. Soil strength has been traditionally measured using a cone penetrometer, which is time-consuming and expensive, making it difficult to obtain the spatial data required for precision agriculture. To improve the current, inefficient method of measuring soil strength, our objective was to develop and evaluate an in-situ system that could measure horizontal soil strength in real-time, while mov… Show more

“…From the comparison of the two grid maps, we can identify that the HSSIs show relatively lower soil strength distributions than the CIs. This result was also obtained by Cho et al (2015), which could be understood as the characteristic of the horizontal strength measurement methods. In other words, as the measured depths decrease, the HSSIs show more similar measurement characteristics to those of the CI values.…”

“…Figure 6 shows the scatter plots of the CI versus HSSI at different depths in the field performance tests. The scatter plots appear to have much more deviated from the 1:1 line than the results of the analysis of the HSSI-CI correlations (r 2 = 0.94) in the artificial soil bins conducted by Cho et al (2015). These deviations are considered attributable to the more diverse environmental conditions than the controlled artificial experimental conditions.…”
