All fertilizers applied to wheat should be sown broad- 

 cast during the preparation of the soil and very thoroughly 

 incorporated with it. Excessive use of Nitrogen is injurious, 

 causing too succulent growth resulting in rust or lodging, 



or both.

wheat to allow this fermentation to pass its most active 

 stage. 



If wheat shows an unhealthy appearance in early springs 

 especially upon sandy lands, an application of seventy-five 

 pounds (?/ Nitrate of Soda will prove beneficial provided there is 

 enough phosphoric acid in the soil to co-operate with it to make 

 the grain.

Experiment with Nitrogen. 



To compare effects of Nitrogen from 

 Obiect. cotton seed meal and Nitrate of Soda and 



the latter applied with the seed and as a top dressing. 



The intention was to use on each plot a constant quan- 

 tity of phosphoric acid and potash as the equivalent of 

 these ingredients in 200 pounds of cotton seed meal. 



The iirst plot received cotton seed meal 



alone, yield i7-5 ^^-'S-

 the seed, yield ^0.8 bus. 



The third received only phosphoric acid

The fourth received in addition to phos- 

 phoric acid and potash applied with the 

 seed. Nitrate of Soda as a top dress, 

 yield 19-4 bus.
