Food for nodules found in their roots. Leguminous plants, in the early 

 Plants sta g es o f their growth, avail themselves of the Nitrates in 



2 3 the soil. Nitrate of Soda has been very profitably used in the 

 cultivation of Lucern, or "Alfalfa," etc. 



Crops that have suffered from wintering, from insects, 

 etc., can, in most cases, be considerably improved by top- 

 dressing with Nitrate of Soda. 



When the soil is very poor in potash, the soda contained 

 in Nitrate of Soda will, to a certain extent, serve as a substi- 

 tute for potash. It is not, however, a perfect substitute. 

 Poverty in potash can be fully made good only by applying a 

 sufficient quantity of a potash fertilizer. 



Nitrate of Soda is easily soluble, and it distributes itself 

 immediately through the soil.
