MANURES AND FERTILIZERS. 6? 



many cases, but generally the cost of these was 

 too much to make their use profitable. The 

 value of phosphoric acid was especially shown 

 in tests in Alabama, Louisiana, Pennsylvania 

 and Vermont; that of nitrogen in Georgia, 

 Massachusetts (local), New York and North 

 Louisiana; that of potash in Kentucky; New 

 Hampshire, New Jersey and Massachusetts 

 (general). 



Cotton seed crushed, or cotton-seed meal is 

 generally considered to be a most desirable 

 nitrogen fertilizer. This used singly or in con- 

 nection with artificial fertilizer is recommended 

 for the corn crop. The meal may be sowed 

 broadcast before planting and harrowed in, 

 while the crushed seeds may be plowed under, 

 as with stable manure. However, it would be

Sea weeds, fish scrap or dead flsh, night 

 soil and other substances are used for manur-

 makes a good nitrogenous manure, and along 

 the coast in places is extensively used. 



Green manure offers a valuables means of 

 improving the soil for corn-growing in localities 

 where the land has been long cultivated. This 

 is for the reason that those crops best adapted
