Our transcription: One of these precautions, a barrier known as a windbreak, is composed of very tall trees.
Wayne Soppeland has relied on this technique to protect his precious soil from the ravages of erosion for a long time.
The windbreaks also protect Soppeland's farm from being smothered by drifting sand.
As Soppeland has learned through the years, a windbreak is extremely effective, provided it's sufficiently dense and tall.
When there is an opening in the protection, or no windbreak at all, the damage can be severe.
