Abstract: Contour tillage is an agricultural practice that significantly contributes to enhancing water retention, reducing the risk of flooding, and mitigating soil erosion. Information about the tillage direction is used for modelling water and tillage erosion. In our study, we used Light Detection and Ranging (LiDAR) visualizations, originally developed for archaeological research, to visualise tillage traces and map tillage direction in the Nitra district (SW Slovakia). The tillage traces were visible in all agricultural parcels, on various agricultural fields, under various agricultural crops. The LiDAR visualisations also revealed pre-collectivization field patterns and even prehistorical field patterns in certain areas. Among the 5 961 investigated points, we recorded the application of contour tillage in 30.63% of the cases. The preference for contour tillage varied among farmers, with the highest reported percentage reaching 49.74%. Our analysis did not reveal a significant correlation between the preference for contour tillage and the slope steepness.
