Abstract: The influence of aluminum in forest soil on the growth of Pinus massokiana was investigated in a tree farm by a new method in which three kinds of soil column were put in the holes near masson pine root system which would grow in it. The results showed that the pH values of soil column added aluminum sulphate to it were very low less roots were found and most of it had died. Whereas the pH values were increased in the soil column of adding calcium carbonate, and total aluminum and active aluminum were decreased, much more lateral roots and root hairs were found Some more related investigation should be continued further.
