When the fertiliser — whichever of the various formulae here indicated is 
adopted — contains pigeon dung, sewage, chrysalis of the silkworm, hoofs 
and horns, codfish or other fish guano, in the following year one must 
use only the chemical ingredients of the fertiliser in the same quantities 
as given in the formula adopted ; the organic constituents must be 
omitted. But if the fertiliser has for its base horse dung or green 
manure, these organic constituents may be omitted for two successive 
years. 
After the two or three years, according to the fertiliser employed, you 
may again use the complete fertiliser. 
For Orange Trees in Full Bearing.

Except under the special conditions of the soil which make it

nitrogen, it is better to apply both forms of nitrogen. In February
