Accurate soil hardness measurement is essential for enhancing agricultural productivity and geotechnical stability. Conventional methods, such as cone penetrometers, offer limited precision they only measure penetration resistance, without considering reaction forces. This study introduces a novel Fiber Bragg Grating (FBG) sensor system, which captures both downward upward push‐back forces, providing more comprehensive evaluation of hardness. By combining theoretical modeling, simulations, experimental validation, the relationship between moisture resistance analyzed. Results show nonlinear correlation content force, with forces ranging from 1.2 × 10 4 N at 0.8 to 7.8 0.2 content, depth 0.01 m. Additionally, FBG‐embedded beam experiences peak deformation 1.25 −6 m 0.25 m, confirming sensor's high accuracy. The dual‐force approach significantly enhances evaluations, offering real‐time, high‐resolution data sustainable management. Furthermore, new equations specific FBG‐based wavelength shifts are proposed addressing limitations conventional methods. advances testing technologies, potential applications in agriculture, engineering, environmental sustainability.

Soil compaction is a widespread problem, leading to soil degradation, yield losses, and adverse environmental impacts. Nowadays, various measurement methods exist assess map compaction, with vertical cone penetration resistance measurements being one of the most commonly used. This method easy, rapid, inexpensive, generally accepted. However, manual are time-consuming, labor-intensive, often less accurate due inconsistent speed. To address these limitations, an automated penetrometer was developed integrated on autonomous robot platform, paving way for high-resolution mapping as starting point precision subsoiling remediate compaction. The performance this setup validated in controlled field conditions against hand-held penetrometer. Therefore, experiments were conducted soil-filled cylinders plots long-term experiment, including across spraying tracks. demonstrated high correlations device under conditions, though correlation somewhat lower soil’s heterogeneity. Deviations between two devices likely caused by insertion speed penetrometer, particularly soils resistance. Both penetrometers successfully identified plow pan at depth 30–40 cm but unable clearly show effect presence
