RESULTS OBTAINED FROM THE PLOUGHING UNDER OF CLOVER. 



In 1900 and 1901 further experiments were undertaken to demonstrate the useful- 

 ness of the ploughing under of clover to add fertility to the soil. The following tests 

 were made with oats, Indian corn and potatoes showing the effect on these crops in 

 1902, of clover ploughed under in 1901. 



In the second series of tables the eifect from the ploughing under of clover in 1900 is 

 shown on the two succeeding crops, those of 1901 and 1902. These experiments were 

 all made on plots of one eightieth of an acre each.
