cleaning crop. The high price of seed 

 at present practically forbids growing clover 

 thus. 



Whether sweet clover grown for renovating uses 

 should be turned under the season in which it has 

 been sown will depend largely on the growth that 

 has been made. In many instances, the growth 

 made is so rank as to justify plowing it under the 

 following autumn. In other instances, better re- 

 sults will follow plowing it under the next season. 

 It frequently happens that the growth made is so 

 rank that a strong plow and also a strong team -are 

 necessary to do the work properly. 



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 of 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 dur- 

 ing the second year of growth. If, therefore, the 

 plants are cut off when in bloom, seed forming will
