FERTILIZER EXPERIMENTS WITH TOMATOES IN THE GREENHOUSE. 



In order to determine something of the fertility of the virgin soil and the rela- 

 tive influence of the different plant food constituents when anplied in the form of 

 chemical fertilizers, a series of tests was started in the greenhouse. 



The soil used was a sandy loam which had not previously been cropped, it having 

 been taken from a field that was broken up out of green spruce and birch stumps the 

 previous season. The bench was filled with this soil to a depth of 5 inches, the soil 

 well worked over and pieces of roots removed and thoroughly mixed so that it was 

 uniform in every particular. /The area occupied by each plot was 2 square yards. 



The respective plots were fertilized with the following amounts per acre. This 

 was thoroughly mixed with the soil by hand.
