Since the time of initiating shelterbelt establishment 

 programs, improved farming methods have been enacted by many- 

 landowners enabling them to better protect their soil from 

 wind erosion than was possible in the later 1920's and early 

 1930's. Studies have shown that depending upon the structure 

 of the soil, adequate protection against wind erosion can be 

 provided by farming methods such as: ridging, strip cropping 

 and stubble mulching. 



The Rural Area Development Forestry Committee feels that 

 technicians should have a basis upon which to recommend certain 

 species of windbreak trees and certain spacings of trees 

 within and between rows in order to accomplish a specific pur- 

 pose whether the job to be accomplished is to provide wildlife 

 habitat, to increase crop yield, to protect homes, feed lots 

 or other . In order to gather data on which to formulate the 

 proper recommendations, field studies of existing windbreaks 

 coupled with research projects to evaluate the effectiveness 

 of various species of trees and shrubs at various spacings, 

 applied to various shelterbelt uses, need to be undertaken . 



The RAD Forestry Committee realizes the need for more 

 study into the effects of field windbreaks and wishes to 

 encourage the undertaking of such studies.
