Fertilizing Ingredients of (1) Alfalfa, {2) Alsyke Clover. 



[I. Alfalfa. Fertilized. II. Alfalfa. Unfertilized. III. Alsyke Clover. Fertilized. 

 IV. Alsvke Clover. Unfertilized. 



The higher per cent, of nitrogenous matter in the crop 

 from the unfertilized plats, over that from the fertilized pUits, 

 finds its explanation in the fact that, owing to the scanty 

 supply of plant-food in the former, the plants matured at an 

 earlier date. The advantages of fertilization are, therefore, 

 not shown in the percentage of nitrogenous matter, but in 

 an increase of total yield of a healthy, vigorous growth.
