Sulfate and Muriate of Potash compared as Fertilizers for Garden C7'ops. 

 — Yield j)er Acre (^Pounds), Average of Three Plots. 



Sulfate and Muriate of Potash compared, etc. — Concluded. 



Examination of the table reveals the fact that the results 

 for this season are the precise opposite of the results which 

 have been ol)tained in most of our previous experiments. 

 The muriate of potash gives the greater yield in the case of 

 all the early crops, and the sulfate of potash the larger yield 

 in the case of all the late crops. It is well understood that 

 muriate of potash dissolves and diffuses through the soil 

 somewhat more readily than sulfate, and, further, that it 

 makes soils more retentive of moisture ; and it may be that 

 the great deficiency in rainfall which prevailed during the 

 season until early in June left the soil so dry that the sulfate 

 of potash did not become sufficiently dissolved and diffused 

 to become available to the early crops. 



The relative average standing of these two salts, as indi- 

 cated by the total yields of all crops grown previous to this 

 year, is shown in the following table : —
