Does a Shelter Belt Pay in Dollars ? 



By Carlos G. Bates, U.S. Forest Serz'iee 



JJ'indbreaks are. in more ways than one. a farm asset. They tend to prevent 

 the soil from drying out quickly and they protect grain and orchards from me- 

 chanical injury by the wind. A belt of trees by the farm buildings protects them 

 from extreme ■winter cold and summer heat, and makes the farm a pleasanfer 

 place in which to live. The windbreak may also be a source of wood supply for 

 use on the farm or for sale. 



The eft'ect of a windbreak on crops 

 is not beneficial in every respect. 

 There are certain ways in which it is 

 plainly injurious. Trees in a wind- 

 break always spread their roots exten- 

 sively into the adjoining fields in 

 search of moisture ; and they take not 

 only the moisture but some of the 

 nitrogen content of the soil. Furth- 

 ermore, by shading the ground they 

 may prevent crops from developing 

 1 iroperly. 



\Vhether the total effect of a wind- 

 'ireak is good or bad depends upon 

 whether the benchits derived from its

influence on wind movement, temper- 

 ature, and evaporation are greater or 

 less than the injury resulting from the 

 sapping and shading of the ground 

 near them. To determine the total 

 effect, crop measurements have been 

 made in Nebraska, Kansas. Iowa, and 

 Minnesota. .Vverage rather than ex- 

 ceptional conditions were measured, 

 the object being to discover the effect 

 of those influences which are continu- 

 ous and affect every annual crop 

 grown. 



Measurements made in fields of 

 small grain indicate that the crop gain
