Experimental plot treated with 50 Kg. phosphatic cinders (14/16 

 P2 05), 8 Kgo. chloride of potassium, 14 Kgo. Sulphate of Iron. 

 Applied in the fall to get the advantage of winter snow and rain. 

 The springtime was unfavorable to growth but the vegetation 

 was vigorous. The yield from this plot did not equal the yield 

 from other plots treated with other fertilizers.

Changes S. of I. undergoes in soil. The sulphuric acid was not 

 retained; the iron replaced by lime and nitrogen.

The effect of Sulphate of Iron on the root system was deter- 

 mined by treating experimental plots with different quantities 

 of S. of I. in the form of a 6% solution. 



Plot No. I received 250 cc. with a resulting germination of 

 70%. 



Plot No. II received 500 cc. with a resulting germination of 



3l%- 



Plot No. Ill received 1000 cc. with a resulting germination of 



40%. 



The plants made an excellent growth and looked healthy and 

 vigorous. Most of plants had three leaves. The root system was 

 well developed, only a few roots being injured.
