sugar beets, it will be found tbat the latter crop, although not 

 as nourishing as the former, is by far the more beneficial to the 

 soil, and not nearly as exhausting. In comparing mangels with 

 sugar beets, we have previously called attention to the percent- 

 age of plant-food taken up by one ton of beets and mangels. 

 In the same manner we may compare the most important of 

 these elements absorbed by one ton of green fodder with those 

 of one ton of beets. 



PLANT FOODS ABSORBED BY ONE TON OF SUGAR-BEETS AND GREEN CORN. 



These figures prove that, ton to ton, sugar beets are more ex- 

 hausting than green corn; but if we admit that the yield of 

 green com is twice that of sugar beets, we would obtain the fol- 

 lowing figures: 



PLANT FOODS ABSORBED TO THE ACRE BY TEN TONS OF BEETS AND 

 TWENTY TONS OF GREEN CORN. 



In other words, green corn takes up per acre 6 Ibs. less soda, 13 

 Ibs. more magnesia, 22 Ibs. more lime, 3 Ibs. more phosphoric 

 acid, and 11 Ibs. more nitrogen. 



These figures are apparently insignificant, but when the 

 deficiency in the soil is to be made up, the dollar cost of the
