What is wind-breaking?
Windbreakers are crops grown for the protection and enrichment of the soil.
Wind breaking is a method of planting and planting and harvesting where stalks and other residue from the previous year are left on the ground into the next season.
Windbreaks are linear planting of trees and shrubs designed to enhance crop production, protect people and livestock, and benefit soil and water conservation.
Wind breaking is planting rows of trees at wide spacings with a companion crop grown in the alleyways between the rows.
