We
began fertilizing and cultivating in 1909, and have put on the 100 acres
about the same amount of fertilizer each year. In 1909 we got 15 tons;
in 1910, 116 tons, and 1911 is estimated at 325 to 350 tons.
It is important that your olive trees are responding to good treatment
and fertilization. Unfortunately, that does not seem to be always the
case and a good many olive trees have been made into firewood because
nothing seemed to bring them into satisfactory bearing. Good bearing
olive trees are now among the very best of our horticultural properties,
while non-bearing olive trees are worth about $7 a cord for fire wood.
Nursery Fertilizers.
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.
