Manuring of Sugar Cane Lands. 



The results of experiments into the ef- 

 fects of long-continued manurings of 

 sugar-cane lands with sulphate of am- 

 monia and with nitrate of soda in the 

 West Indies, and whether better re- 

 sults would not be obtained by the sub- 

 stitution of one nitrogenous manure for 

 the other, show that the substitution of 

 nitrate of soda on non-limed land for 



a reduction of the increased yield, due 

 to the nitrogenous dressing, from 12.1 

 tons to 10.3 tons, while the substitution 

 of sulphate of ammonia for nitrate of 

 soda on the nitrate fields increased the 

 yield from 8.6 tons to 9.2 tons per acre. 

 On limed soils the substitution of ni- 

 trate of soda for sulphate of ammonia 

 reduced the yields due to nitrogenous 

 manuring from 11.8 tons to 8 tons per
