%description
Provides tools to record, validate, and analyse soil tillage depth and
erosion across years and field treatments. Includes functions for
year-wise tillage operation summaries, erosion depth tracking, compaction
detection, soil loss estimation, and visualisation of temporal changes in
tillage and erosion profiles. Methods follow Lal (2001)
<doi:10.1201/9780203739280> and Renard et al. (1997) "Predicting Soil
Erosion by Water: A Guide to Conservation Planning with the Revised
Universal Soil Loss Equation (RUSLE)"
