FEEDING THE HOP PLANT. 



A GOOD CROP OF HOPS WILL TAKE FROM AX ACHE OF LAND 



These are astonishing figures. Their significance 

 can be best judged by comparison with the plant food 

 removed from an acre by other crops under equally 

 good culture, it being assumed that the hop vines, like 

 potato vines and cornstalks, are returned to the soil: 



PLANT FOOD REMOVED FROM AN ACRE BY SEVERAL CROPS 



How few hop planters in New York state realize 

 that for a good crop of hops they must manure as heav- 

 ily as for 40 bushels of corn per acre, simply to supply 

 what is taken from the soil by the dry hops. If we 

 consider both vines and hops, we get this table, 

 showing: 



COMPOSITION AND QUANTITY OF MANORIAL SUBSTANCES REQUIRED 

 TO SUPPLY WHAT AN ACRE OF HOPS TAKES FROM THE SOIL 



This weight of wood ash (containing only 12% water) will supply 

 the full amount of potash taken off by the hop crop (vines and hops) 

 but no nitrogen; the other weights given will furnish the full amount 

 of nitrogen, but more or less of potash and phosphoric acid than the 

 crops take off, except in the case of bone meal. 



Stable manure is the form of plant food preferred 

 by both European and American hop growers. In
