A remarkable demonstration in the growing of sweet clover
was made on the Berea Field in 1916-17. On the undrained i
part of the field. approximately 31/2 acres were limed at the
rate of 2 tons of ground limestone per acre and treated with
aeid phosphate at the rate of 300 lbs. of acid phosphate per
aere, and seeded to sweet clover in the spring of 1916. This
ground is so wet that it is often as late as the first of May he-
fore it can he plowed. No winter grain can he sueeessfully
grown upon it without drainage. ~
The sweet elover was harvested for seed in 1917. and pro- A
duced 975 lhs. of seed in the hull. as cleaned for market. The
straw was put hack on the ground and plowed under for eorn-
in 1918.
