As a soiling crop sweet clover has been used to only a very limited
extent. The amperage yields of green matter vary from 6 to 15 tons per
acre, The season for soiling may commence when the plants are 12 to
15 inches high and continue until flower buds appear. An area of such
a size that the plants may be cut every four or five weeks should be
selected. The plants should not be cut closer to the ground than 4
inches during the first part of the season and 9 to 12 inches during
the latter part of the season. On account of the high protein content
and the large amount of forage produced on a relatively small area,
sweet clover may profitably be fed in this manner when more desirable
soiling crops are not to be had.
