58 TKUCK-FAKMIHQ AT THE SOUTH. 



Sixth. To make the heaviest applications of manure to 

 such crops as require most, as cabbage, onions, etc; and 

 have other crops succeed those requiring less, as tomatoes, 

 egg-plants, etc., so that the whole farm may be gradually 

 brought to the same degree of fertility. 



As the crops of the truck-farmer come in for ship- 

 ment during spring and early summer, there is rarely 

 an opportunity of having a second crop occupy the same 

 ground, before the first is harvested; still it may occur. 

 Thus a crop of melons or cucumbers may be put in be- 

 tween the wide rows of peas. The latter will be off be- 

 fore the former requires the first working. 



A further benefit of successive rotation and continued 

 cropping is the destruction of noxious weeds, and of such 

 insects as prey for more than one season on the roots of 

 a particular kind of crop, by depriving them of their 

 food. 



A continued liberal use of the same fertilizer, although 

 it be the complete stable-manure, will eventually show 

 less favorable results, than when manures are alternated. 

 Owing to a too limited use, this will not frequently 

 happen on our truck-farms; but it may occasionally occur 

 near cities, where, after a series of heavy manurings with 

 stable-manure or night-soil, the land seems to crave 

 something else. A resort in such a case to a good com- 

 mercial fertilizer will remedy the evil and increase the 

 crop.
