Progressive bench terrace

Bench terraces are progressively expanded to form a fully developed terrace system in order to reduce runoff and soil erosion on medium- to high- angled loess slopes. The technology is mainly applied to tree plantations.

Soil from the upper parts of the slope is removed and deposited below in order to extend the flat terrain. Over 5-10 years, the terraces become enlarged around each tree and form a terrace with the neighbouring trees along the contour, such that the slopes are transformed into level bench terraces. The trees are located in the middle of the terrace. All the work is done manually using shovels.
