It will be noticed that plot 3, where nitrate of soda was used shows only 9 ounces 

 gain in growth over the check plot. Also it will be seen that the gain in fruit is 

 only 2 pounds, 2 ounces over the check plot. Where nitrate of soda and sulphate «f 

 potash was used on plot 4 there is a gain of only 13 ounces in growth over the check 

 plot; also the gain in fruit is only 3 pounds 1 ounce. On plot 5, where acid phosphate 

 and nitrate of soda were used there was a gain of 2 pounds in growth over the check 

 plot, and a gain in fruit of 6 pounds 10 ounces over the check plot. Since there is 

 little gain from the nitrate of soda in plot 3, we may fairly assume that acid phosphate 

 has been largely responsible for the increased yield. In all cases where the acid 

 phosphate has been increased there has been an increased growth and increased crop. 

 It would appear that our soils are principally deficient in phosphorus.
