RELATIVE FAEM VALUE OF CROPS.

Table XXIII. — Gain or loss of each rotation for each test as compared with continuous 

 cropping by ordinary methods. 



[The plus sign indicates gain in favor of rotation and the minus sign loss— in terms of dollars and cents 

 per acre for wheat and oats or barley and oats in each rotation. The best rotation, excepting Nos. 5 

 and 8, each of which has one fallow year and is therefore not strictly comparable with the others, is 

 printed in black-faced type.]
