RETORT OF FIELD EXPERIMENTS. 



99 



cwts. of superphosphate. The crop before had been seeds, before 

 that wheat and permanent pasture. 



The cabbages were drum head, and stood 8 to 9 inches high 

 on May 14th, when the dressings were applied in quadruplicate 

 on s\th of an acre. The field was in "lands" like the wheat 

 field. The dressings were applied along each row, of which there 

 were three on a land. The advantage of dryness was plainly 

 marked by the great superiority of the row on the middle of the 

 " land" which stood the highest. 



The cabbages grew pretty well till September, when, owing to 

 the perpetually drizzling rain without sunshine — for there was 

 only one day in the whole month when there was not rain — the 

 cabbages became blighted, stopped growing, and lost their out- 

 side leaves. They were cut, and the heads weighed the first 

 week in November. 



Table VI. contains the weights per plot. Table VII. contains 

 the calculated weight per acre. 



It is seen from these tables that Peruvian guano has had a 

 most marked effect, having nearly doubled the crop, the heads 

 were far more compact, and there was less loose leaf. Ammonia 

 salts, as well as the nitrates, have had a marked effect, though 

 not equal to the guano. 



The effect of these dressings has been so great on a very small 

 crop, that the results lead to the conclusion that, under more 

 favourable circumstances, the application of some of them would 

 pay the farmer.
