18 [ ASSEMBLY 
According to these analyses a ton of the green plant and root would 
contain 12 lbs. of nitrogen and 58? lbs. of ash, containing 4.47 lbs. 
phosphoric acid, and 28.95 lbs. of potash. Hstimating the nitrogen, 
etc., at lowest market rates we have for an indicated value per ton of 
green plant for green manuring, 12 lbs. nitrogen at 24 cents, $2.88 ; 
4.47 lbs. phosphoric acid at 6 cents, 26 cents; 28.95 lbs. of potash at 
5 cents, $1.44. Total, $4.58 per ton. 
In green manuring, however, the nitrogen is the only portion of the 
fertilizer which is saved from waste; the other ingredients do not 
wash from the soil.
