Detection of soil management practices using Sentinel-1 time series: the challenges raised by the diversified management sequences in vineyards

Résumé

Characterization of soil management strategies in the complex agroecosystems of vineyards is crucial to evaluate their impact on vineyards soil health, particularly in the context of increasing soil threats posed in semi-arid environments [1], [2], [3], [4]. This study evaluates the potential of Sentinel-1 (S1) radar times series to detect soil management practices in Spanish vineyards. Two trellis-trained vineyards plots (ca. 4 ha each) located in the Toledo province (Spain) were studied, each subjected to a distinct soil management practice: conventional tillage (TILL) and a cover cropping system (CC), respectively. A farmer survey was conducted to thoroughly document the sequence, timing, and spatial distribution of management operations carried out between October 2020 and August 2024. A methodology based on S1 radar signal change detection was applied to detect soil surface roughness associated with these practices. The survey data served as a reference to evaluate the accuracy of the S1-derived detections. Results revealed a very high degree of variability in vineyards management practices, in terms of type, spatial distribution and frequency within these fields. Despite such diversified management sequence, satellite-based detection was effective on average, over more than 60% of the plot surface area, for tillage for both TILL and CC plots, weed control and rolling for only CC plot. Additionally, mechanical pruning was successfully detected in the TILL plot. Our further research will explore the integration of S1 radar data with S2 optical imagery to refine this detection and assessment of soil management practices in viticultural systems.
