These results show that, with each ton of first cutting 
hay, there is removed an average amount of 143 pounds of 
ash constituents ; with each ton of second cutting hay, 165 
pounds; and with the third cutting, 127 pounds per ton. 
Our sample of red clover gives 128 pounds against 143 
pounds for the alfalfa. The following are the amounts of 
the most important plant foods taken from the soil and air 
by the successive cuttings of alfalfa and red clover hay per 
ton of 2,000 pounds : 
Nitrogen. 
Phosphoric 
Acid. 
Potash. 
Sulphuric

This table gives the amount of plant food removed by 
a ton of average hay ; but if the amount removed by 
an average crop is desired, we have taken 1.65 tons for first
