Field shelterbelts increase yields of field and forage crops throughout the world. The increases are due to reduced wind erosion, improved microclimate, snow retention and reduced crop damage by high winds. Crops differ in their responsiveness to shelter. Of the field and forage crops tested, winter wheat, barley, rye, millet, alfalfa and hay (mixed grasses and legumes) appear to be highly responsive to protection, while spring wheat, oats and corn respond to a lesser degree. Shelterbelt height and longevity, field width and shelterbelt orientation are major considerations in determining the effect of shelterbelts on crop yields. Precipitation has an effect on the percentage yield increase reported. Generally, percentage yield increases due to shelterbelts have been higher in drier regions or in drier years. By proper shelterbelt design and maintenance and the use of responsiveness crops, shelterbelt benefits to crop yields can be optimized.
