GRASS GROWING FOR PROFIT 37 
INCREASED YIELD BY THE USE OF NITRATE OF 
SODA. 
The increased yields of crops resulting from a 
top-dressing with Nitrate of Soda are most striking. 
In an article recently published by Dr. E. J. Russell, 
Director of the Rothamsted Experimental Station, 
the following figures are given. On an ordinary 
farm where the land, while in fairly good heart, has 
not been over well done, a farmer may reasonably 
expect the following increases from a top-dressing 
of 1 cwt. of Nitrate of Soda: 
Per 1 cwt. super-

For purposes of comparison the effect of phos- 
phates is shown also. , 
It should be remembered that plants take up 
most of their Nitrogen during the early period of 
their growth. 
Nitrate cannot take the place of intelligent soil 
management which includes proper cultivation. 
Chilean Nitrate never leaves the soils in an acid 
condition and there is no harsh and unwholesome
