MEADOWS AND PASTURES 



"The following figures show the comparative effects of 15 cwt. 

 slag on Plot 11, and 10 cwt. slag on Plot 3 for six years after appli- 

 cation, the former having been applied for 1900, and the latter for 

 1897. (Plot 11 was started three years later than the others and its 

 results therefore are not included in the table). The better results 

 given by 10 cwt. slag may be partly accounted for by the fact that 

 while 10 cwt. slag developed 20 per cent of clover two years after 

 its application, 15 cwt. increased it to over 35 per cent, but York- 

 shire fog was developed to the extent of nearly 50 per cent four 

 years after the heavier dressing of slag, whereas it increased in 

 the same time to less than 20 per cent by the lighter dressing. This 

 large amount of fog is the likely cause of the smaller returns from 

 the heavier dressing of slag in the later years. 



LIVE-WEIGHT INCREASES IN POUND PER ACRE (OVER PLOT 6). 



"The soil of Plot 11 is more variable in character than that of 

 the other plots, and there were slight differences in the treatment 

 of this plot in the earlier years, but the fact that the results here 

 were probably the same as those on the untreated plot for three 

 years before the application of the slag, renders the foregoing re- 

 sults fairly reliable. Plot 5 had 7 cwt. superphosphate per acre ap- 

 plied for 1897 and the same for 1900. This contained the same 

 amount of phosphoric acid and was applied at the same times as 

 the two dressings of slag on Plot 4. In the first three years super- 

 phosphate gave a total live weight increase of 125 pounds as com- 

 pared with 132 pounds from slag similarly applied on Plot 4. Super-
