THE SYSTEM OF FAEM-YAED MANUEING. 



Fig. IV. 1854. Clovek. 



Ill Fig. I., tlie perpendicular lines a h represent the 

 produce of grain, a c that of straw ; in Fig. II., the lines 

 de the produce of potatoes ; in Fig. III., the hnes/^ the 

 produce of oat-corn, the lines fh that of oat-straw ; in 

 Fig. IV., the lines i h the produce of clover, on the un- 

 manured plots of ground on which the experiments were 

 made in Saxony. 



Now if we assume that the roots of the rye and of the 

 other plants, on the several fields, were of the same 

 length and condition, it is quite certain that the roots of 

 the cereals on the field at Mausegast found, in their way 

 downwards, much more nutriment than those in the 

 Cunnersdorf field : the corn line is twice as high, and 

 the straw line one-tliird higher, in the former than in the 

 latter. 



With an equal number of plants, and an equal length 

 of root, certain nutritive substances required by corn 

 were twice as close in the Mausegast as in the Cunners- 

 dorf field. The fine in Fig. IV. representing the produce 

 of clover is ten times as high for Cunnersdorf as for
