and retentive nature where the use of nitrate of soda 

 is apt to result in a bad texture of the surface. Nitrate 

 of lime will undoubtedly become a very valuable 

 fertilizer, one, again, which acts as a basic substance, 

 and is therefore valuable on sour soils. 



These new nitrogenous fertilizers, the number of 

 which will certainly be soon increased, have been 

 proved to be of real value ; they belong to the active 

 sources of nitrogen and are to be ranked with nitrate 

 of soda and sulphate of ammonia and valued on the 

 same basis. Which of the four the farmer should buy 

 may be settled in the main by the price per unit of 

 nitrogen, though the nature of the crop and the soil 

 should also be considered. Barley and turnips answer 

 better with nitrolim and sulphate of ammonia, though 

 the latter should be avoided on soils short of lime or 

 where finger and toe prevails. The nitrates are better 

 for wheat, mangolds, and grass, and nitrate of lime 

 should have the preference on very heavy working 

 soils.
