No nitrogen is required by these plants unless the soil is absolutely deficient 
in this plant food, and then it is advisable to give a little to start the plants till 
they are sufficiently strong to provide their ownnitrogen. These plants require 
a considerable proportion of potash, so that in all soils that are deficient in this 
respect, a fertiliser rich in potash must be used. Foran average soil the 
following will be found to answer: cwt.

This will contain 8 per cent of potash, 18% per cent of phosphoric acid, of which 
5 per cent. is water soluble, and is worth £5 12s. per ton. 
From 5 to 6 ewt. to the acre, mixed thoroughly with 
should be a fair dressing in soils of average quality. 
The following table, which has been obtained from a number of European 
and American sources, gives the total amount of ash removed from the soil by 
1,000 1b. of the following fruit—farm and garden crops, as well as the composi- 
tion of the ash, showing the relative proportions of phosphoric acid, potash, and 
nitrogen. In the case of the nitrogen, the amounts given represent not only 
that contained in the ash, but also that contained in the albuminous matter of 
the fruit or plant. 
As previously stated, the mere fact that a given crop takes so much out of 
any given soil cannot be considered accurate under all conditions, but is at the 
best only an approximation. At the same time, it is of value, as indicating the 
particular plant foods which are required by different crops; and when this 
knowledge is combined with the experience gained by the practical application 
of manures and commercial fertilisers, it-will be found to be of great assistance 
to all agriculturists.
