After the first year the amounts of plant food prescribed 

 should be liberally applied fairly early in the spring. After 

 one begins to cut shoots, it may be well, in addition to this early 

 application, to use at the close of the cutting season, 100 pounds 

 of nitrate of soda, 200 pounds dissolved rock and 100 pounds 

 of muriate of potash, or 400 pounds of kainit in place of muriate. 

 The exact amounts to use must be governed by individual 

 experience.

Nitrogen.

 Potash 



4 12 to 24 25 to 50 pounds nitrate of soda; 20 

 to 40 pounds sulphate of am- 

 monia; 40 to 80 pounds dried 

 blood.

8 25 to 50 50 to 100 pounds muriate of pot- 



ash. 



Suggestions. — Barley is a strong-feeding crop and can utilize 

 forms of food not easily available for wheat. Excessive applica- 

 tion of nitrogen compounds is to be avoided, when barley is 

 grown for grain. Large applications of stable manure should 

 not be applied directly to the crop on this account, but may be 

 used safely on the crop preceding barley in a rotation. 



When barley is grown with peas as a forage crop, much larger 

 amounts of quickly-available nitrogen can be used with advantage.

Suggestions. — The formula given above applies to beans grown 

 for the seeds. When beans are grown to be eaten green, as for 

 string beans, more nitrogen should be applied, as this tends to 

 develop foliage and tender pods and retard ripening. For such
