FERTILIZERS FOR MUCK SOILS. 157 



dollars per acre, according to the price you have to 

 pay for the ashes and phosphates. Leached ashes 

 should be used more liberally, one to two tons per 

 acre not being any too much. 



In case ashes are not to be had, or too dear, we 

 must rely on other forms of potash, and I would 

 recommend any of the following formulae, viz. : 



1. 1,000 pounds phosphatic guano (or dissolved bone or 



rock; or Thomas' slag). 

 1,000 pounds Kainit; 



Cost per ton about $20.00. For grains and grasses. 

 Quantity per acre, 300 to 500 pounds, applied in fall, 

 winter or early spring. 



2. 1,000 pounds superphosphate (dissolved bone, or its 



equivalent), 

 1,000 pounds sulphate of potash (if high grade, the pro- 

 portion should be changed to about 1,200 pounds 

 superphosphate and 800 pounds sulphate of potash). 



Cost per ton, $35.00 to $40.00. For potatoes, root 

 crops and general garden vegetables. Quantity per 

 acre, from 600 to 800 pounds or more. If muriate or 

 kainit are substituted for the sulphate of potash, 

 the application should be made in winter or early in 

 spring. 



The chlorides in these potash salts are quite 

 abundant, and should be given a chance to be 

 washed out of the soil, as otherwise they are often 

 injurious, if ai)plied in liberal doses. 



3. 1,000 pounds cotton-seed hull ashes, 



1 ,000 pounds superphosphate in any of its forms. 



Cost per ton, $22.00 to $28.00. For grains and grasses. 

 Quantity per acre, from 250 to 300 pounds. For po- 

 tatoes, root crops, and garden vegetables, use more 

 cotton-seed hull ashes and less phosphatic manures.
