MANURES ON WHEAT AND EARLEY. 



liie following is a selection from a report of expeiiinents made by 

 Messrs. H. F. & A. Harwood, at Ipswich, England, in 1872, on light 

 laud which had been cropped in 1870 with wheat, manured with 10 tons 

 of farm-yard dung per acre, and in 1871 with barley, manured with 5 

 cwts. of mixed artiticial manures per acre. This barley crop having been 

 removed, equal plots were measured off, various manures applied, at a 

 cost of £3 10s. per acre, in each case, and wheat sown. Other plots 

 were marked off for barley. The table gives the descriptions of manures 

 and the quantities applied per acre, and the results obtained. The 

 superphosphate received by wheat plots 11 and 15 contained, respect- 

 ively, 28 per cent, and 17 per cent, of soluble phosphates. In addition 

 to the merchantable grain represented in the column of yield, there was 

 a small amount of refuse grain, the value of which is included in the 

 statements of total values of the crops.

 localities.
