The nitrogen content in 1A3, 3A2, 4A2, and 2A, may be considered 

 as fair. The potash in the subsoils of 1A3, and 3A2, is also fair, and the 

 lime content in 1A3, 1A4, 3A2, and 4A2 is satisfactory for soils of a 

 sandy character. With these few exceptions, these soils show a general 

 deficiency in plant foods when compared with a soil of good quality. 



It will be noticed that the percentage of phosphoric acid in all of the 

 soils is particularly low, and the analysis generally shows that the amount 

 of plant food contained in the soils under review would not be sufficient 

 for the needs of the plant for any length of time. On the other hand, 

 there is no reason to suppose that, with good cultivation and the addition 

 of fertilizers for the supply of plant foods, payable crops could not be

grown. The soils would, no doubt, respond to treatment with artificial 

 fertilizers, but systematic experiments in this direction would be necessary 

 in order to ascertain the most effective manure. 



A chemical analysis by means of an acid extraction only goes so far 

 as to afford some information as to the permanent value of soils, but it 

 is generally found that those showing a high percentage of plant foods 

 are capable of yielding good crops, provided that extreme physical condi- 

 tions do not interfere with the growth of the plant. 



Harvested Crops. 



Besides the manurial tests srt out above, the following vegetables were 

 grown during the year: — - 



Potatoes. — One arre was planted with the following varieties, viz., 

 Adirondack, Brown Hill Beauty, White Prolific, Sutton's Abundance,
