75 per
ton. It is not a good idea to apply these organic manures directly for
the growth of potatoes. It is better to apply them to the land for the
growth of a grain or forage crop, plowing in the stubble and using the
land for potatoes the following year. If you wish to fertilize directly
for potatoes, the use of a commercial fertilizer containing a good
amount of potash would be a better proposition.
Fertilizer for Sweet Potatoes and Melons.
I have sandy soil that has been used for sweet potatoes until it is worn
out for that crop, and would like your advice as to the best fertilizer
to use. Also, what fertilizer would be best for melons on land that has
been planted to melons for the past three years?
There is not much difference in the plant food required by the two crops
you mention, but both evidently need a freshened soil and an increase of
humus. We should apply a half ton to the acre of a complete fertilizer,
of which any dealer can give you descriptions and prices. If you wish to
do a good job, start a growth of peas or vetches or burr clover, and sow
the fertilizer evenly with the seed. Plow the growth under in February
and roll (as the soil is sandy) to close down and promote the decay of
the green stuff, which ought to be so well accomplished by the date that
it is safe to plant sweet potatoes or melons that it will give no
trouble in summer cultivation.
