We quote the following from the bulletin of the Rhode Island Station 

 on the effect of wood ashes as a fertilizer, and the supplementary constitu- 

 ents which should be used in connection with them: 



"We find that farmers in most sections of Rhode Island highly esteem 

 wood ashes as a manure, and in many localities they seem to hold a rank next 

 to barnyard manure. From repeated inquiries made in many sections of the 

 State it appears that the beneficial effect of wood ashes is, almost without 

 exception, attributed to the direct manurial action of the potash which they 

 contain, yet it is usual to hear that the effects ffom a single application are 

 often visible for from ten to fifteen years. When we consider, however, that 

 100 bushels of ashes weighing about 4,500 pounds would, upon the average 

 basis of 5 per cent, of potash, contain but 225 pounds of actual potash, which 

 is equivalent to but 450 pounds of muriate of potash, it would seem at least 

 astonishing that an after-effect from such an application should be visible 

 for from ten to fifteen years unless it were due in a considerable measure 

 to something other than the small amount of potash it contains. An appli- 

 cation of a ton of potato or vegetable fertilizer containing 10 per cent, of pot- 

 ash would supply 200 pounds of potash, equivalent to 400 pounds of muriate 

 of potash, or an amount nearly equal to that supplied by 4,500 pounds of 

 wood ashes; and yet we practically never hear of any long continued after 

 effect from the use of muriate or sulphate of potash, or of chemical fertilizers 

 which contain them. Wood ashes contain on an average about 1.5 per cent.
