CROPS AND SOIL IMPROVEMENT 



follow. Some fall growth, and the protection 

 from leaching, should equal any advantage arising 

 from rotting the bulky growth in the soil. In 

 some regions it is not good practice to plow down 

 a heavy green crop on account of the excessive 

 amount of acid produced. When this has been 

 done, the only corrective is a liberal application 

 of lime. 



Mammoth Clover. When clover is grown with 

 timothy for hay, some farmers prefer to use 

 mammoth clover in place of the medium red. It 

 may be known as sapling clover, and is accounted 

 a perennial, though it is little more so than the red. 

 It is a strong grower and makes a coarse stalk 

 but, when grown with timothy, it has the advantage 

 over the red in that the period of ripening is more 

 nearly that of the timothy. It inclines to lodge 

 badly, and should be seeded thinly with timothy 

 when wanted for hay. The roots run deep into 

 the soil, and this variety of clover compares favor- 

 ably with the medium red in point of fertilizing 

 power, the total root-growth being heavier. While 

 its yield of hay, when seeded alone, is greater than 

 the first crop of the red, its inclination to lodge 

 and its coarseness are offsets. It produces its 

 seed in the first crop, and the after-growth is
