crops. No cure or certain prevention when soil has become 

 infected is known. Rotation of crops, no one of this group to 

 be put upon any given field oftener than once in four years, 

 and a rather free use of lime, will help secure immunity. After 

 soil has been brought into condition by one good initial liming 

 a yearly application of a mild lime at the rate of five hundred 

 pounds per acre should be sufficient. If slag meal be used for 

 all crops in the rotation (except potatoes if they be included), 

 it is probable that a second liming will be unnecessary.

The Use manuring, and barnyard or stable manures 



of Manures. are well suited to all except turnips or 



Swedes for table use. For these it is best 



to avoid the too free use of such manures, as the roots are less 



smooth, stronger in flavor and more liable to be attacked by 



worms. For all these crops, manures from animals fed refuse 



from any of them should be avoided as such manures will be 



likely to carry disease germs. This is particularly true of hog 



manure or manures on which hogs run, because these animals 



are often fed waste vegetables, which usually means those which 



are diseased, and which, therefore, carry the germs of disease. 



Manures should, in general, be plowed in or deeply disked under. 



All crops of this family are dependent in a 



Fertilizer Needs, very unusual degree upon a liberal supply 



of phosphoric acid in highly available forms. 



Acid phosphate, dissolved bone and basic slag meal prove highly 



beneficial. When manure is freely used no other fertilizer than 



a phosphate may be necessary. These crops are less dependent 



upon artificial potash supply than most, and it may be doubted 



whether potash in addition to manure will be called for. Some 



nitrate to push'the plants rapidly from the start makes it easier 



to prevent serious injury from lice and some other insects, and 



is always desirable in connection with moderate applications of 



manure, especially for early crops.
