I have light sandy loam, well drained. It has been in blackberries, and
I now have it planted to nursery fruit tree stock. I have given it this
spring two applications of nitrate of soda, but no other fertilizer.
Will the nitrate act alone, or must I apply also the phosphate and
potash to get results?
Nitrate of soda will act alone and will stimulate growth, and there are
cases in which there is enough phosphate and potash already in the soil
to act with it. Usually, however, it is customary to use a complete
fertilizer containing phosphate and potash as well as nitrogen, in order
that the plant may be more roundly supplied and promoted, and one would
be a little safer in using that sort of fertilizer than in relying upon
the nitrate of soda alone. You will, of course, be careful not to use
these fertilizers in too large amounts, for nitrate of soda is
especially dangerous if used in excess.
