THE SYSTEM OF FAEM-YAKD MANURING. 



now, taking the increase to be caused by manure, it is 

 natural to suppose that the same quantity of manure 

 would produce the same increase upon different fields. 

 The following table, however, shows that the same 

 quantity of manure, upon the Saxon fields, produced 

 results which differed very considerably. 



One hundred cwt. of farm-yard manure gave increased produce. 



No one looking at these numbers could divine that 

 they were intended to represent the effects produced 

 upon five different fields by an equal quantity of the 

 same manure, and that too the universal manuring 

 agent. 



Neither in the crop of rye-corn and straw, nor in 

 that of potatoes, oats, and clover, is there the slightest 

 resemblance or correspondence ; still less is it possible 

 to discover what amount of manure has been instru- 

 mental in producing the increased crops. 



The same quantity of farm-yard manure gave, in the 

 years 1851 and 1853J at Mausegast double, at Cunners- 

 dorf three times, the increase of cereal crops, corn and 

 straw together, that was obtained at Oberbobritzsch : 

 the increase of the potato crop at Mausegast was twice 

 as large as in Kotitz ; of clover, four times more in 

 Mausegast than in Cunnersdorf; and in Oberbobritzsch, 

 ten times as much as in Kotitz. 



The enormous quantity of farm-yard manure put 

 upon the field at Oberschona failed to produce anything 

 like the crop obtained from the unmanured field at 

 Mausegast.
