COMMERCIAL SOURCES OF PLANT-FOOD
Some sulphate of potash is imported into this
country. Its content of potash may vary 1 or 2 per cent below or above
50. Its physical condition favors mixing more than does the muriate. It
usually costs several dollars a ton more than the muriate, and the fact
that it is known to favor quality in tobacco, and is popularly supposed
to do so in the potato, creates demand at the higher price. It is
soluble in water, and quickly available. As a rule, it has no higher
agricultural value than the muriate.
