 trees that are in sod are usually making a very poor growth as compared 

 with that of those that are tilled. Probably more damage is done to

 the damage is lessened. 



Yields of tilled and sod orchards. As shown by table 4, the five-year 

 average yield of orchards that have been tilled ten years is 86 per cent 

 larger than that of those that have been in sod ten or more years, and those 

 tilled five years gave 34 per cent larger yield than those in sod five years. 

 This computation, like all others, was made for Carlton and for the 

 remainder of the county separately. But the conclusions shown were the 

 same in each case, therefore the totals only are given.
