 EXPERIMENTS WITH FERTILIZERS OX PLOTS OF OATS— Continued. 



Fertilizers applied each year, from 1889 to 

 18i)8 or 1899. No fertilizers used since. 

 Clover sown in 1899 and each year since 

 with the grain and ploughed under in 

 the autumn.

The one-tenth acre plots of wheat, barley and oats had by the end of 1903 become 

 infested with several troublesome perennial weeds, hence it was thought best to sow 

 only one-half of each plot with grain in 1904, devoting the other half to a hoed crop 

 to clean it. On this account no clover was sown oil any of the cereal plots in 1904, and 

 one-half of the wh€*'t plots was sown with mangels, one-half of the barley plots with 

 potatoes, and one-half of the oat plots with carrots, computing the yields of grain from 

 a one-twentieth acre plot in each case.
