agus sections. The objections made against stable 
manure are that it is more expensive to handle, that it 
is apt to get the land full of weeds, and that it does 
not contain sufficient phosphoric acid and potash. At 
present many growers use commercial fertilizers exclu- 
sively, convinced that asparagus needs liberal feeding 
of potash and more nitrogen than is generally sup- 
posed to be required. 
The composition of 1,000 parts of fresh asparagus 
sprouts is, according to Wolff:

This analysis shows very accurately what a given 
weight of asparagus abstracts from the soil, but it does 
not, and can not, show or even indicate certain indis- 
pensable demands. In this, as in other cases, the 
analysis of a crop is a very uncertain guide to its 
proper fertilization. It should be clearly understood 
by every cultivator of the soil that no rigidly fixed 
formulas can be given for any one crop on all soils. 
The question of quantity of application and of pro- 
portion must always, in the very nature of the case, 
remain more or less a matter of individual experi-
