Since trees once removed take some time to replace, a careful estimate of 

 the effect of a tree removal program should be made before taking this 

 irrevocable step on the basis of snap judgment.

RESEARCH FINDINGS FROM OTHER AREAS 



The Effect of Cover Crop Management on Soil Moisture in a Young Apple Orchard 



The effect of cover crop management on soil moisture in a young apple orchard 

 was studied by Russell Eggert, Department of Horticulture, University of New 

 Hampshire, the results of which should be of interest to fruit growers. The study 

 was conducted in a young apple orchard at the University of New Hampshire to 

 determine the effect on soil moisture of not mowing orchard cover during the 

 months of June to August, or mowing either once or twice, in some instances 

 letting it lie and in others removing it. The orchard cover was similar to that 

 found in Massachusetts orchards being principally Canada Bluegrass intersperse 

 with some "quack" grass. 



Soil moisture readings showed that failure to mow grass cover in early June 

 resulted in rapid depletion of available water from the soil at both 12 and 30 

 inch depths during the two growing seasons that the experiment was conducted 

 (June and July, 1951 and 1952.) 



"The practice of mowing grass cover in early June, and of leaving it in 

 place, delayed the start of second growth and was more effective in conserv- 

 ing moisture early in the season than when the mowed cover was removed. This 

 was true at both the 12 and 30 inch depths."
