Fertilizers applied each year from 1888 to 

 1898 or 1899. No fertilizers used from 

 that time to 1905. Clover sown in 1900 

 in place of the corn and ploughed under 

 in May, 1901, before the corn was planted. 

 In 1903 clover was again sown and 

 ploughed under in May, 1904. In 1905 

 fertilizers again applied as in 1898. Clover 

 discontinued.

PLOTS OF MANGELS AND TUENIPS. 



In conducting these expei'iments, the roots only have been taken from the land, 

 the tops have always been cut off and left on the ground to be ploughed under, so that 

 the plant food they have taken from the soil may be returned to it. One half of each 

 one-tenth acre plot in the series has been devoted to the growth of mangels, and the 

 other half to turnips, and these crops have been alternated from year to year. The 

 preparation of the land has been the same for both these roots. Until 1900 it was
