Value On Alkali Soils
This plant has been grown to some extent to
aid in removing alkali from soils superabundantly impregnated with the
same. It will grow, it is claimed, under certain conditions on such
soils so surcharged with alkali as to prohibit almost every other form
vegetable growth. The extent to which it may be thus used profitably
had not yet been fully demonstrated. But where it can be grown on such
soils, the fact that it takes up and removes relatively large quantities
of alkali would appear to be well established.
=Destroying the Plants.=--Should the conditions be found so favorable to
the growth of the plant that it persists in growing where it is not
wanted, it will soon cease to appear, if prevented from going to seed.
Ordinarily, the blossoms appear only during the second year of growth.
If, therefore, the plants are cut off when in bloom, seed forming will
not only be prevented, but since sweet clover is a biennial, the plants
will die. When thus dealt with, the only source from which other plants
may come while extermination is being thus sought is from seed lodged in
the soil and still capable of germinating.
