When really wet it can be
dipped up with a spoon. Hardpan is down about 24 to 36 inches. I have
tried blowing up between the vines with dynamite, and see little
difference. Can you suggest anything to loosen up the soil?
You could not reasonably expect dynamite to transform the character of
the surface soil except as its rebelliousness might in some cases be
wholly due to lack of drainage - in that case blasting the hardpan might
work wonders. But you have another problem, viz: to change the physical
condition of the surface soil to prevent the particles from running
together and cementing. This is to be accomplished by the introduction
of coarse particles, preferably of a fibrous character. To do this the
free use of rotten straw or stable manure, deeply worked into the soil,
and the growth of green crops for plowing under, is a practical
suggestion. Such treatment would render your soil mellow, and, in
connection with blasting of the hardpan to prevent accumulation of
surplus water over it, would accomplish the transformation which you
desire. The cost and profit of such a course you can figure out for
yourself.
Is Dynamite Needed?
I have an old prune orchard on river bottom lands; soil about 15 or 16
feet deep. Quite a number of trees have died, I presume from old age. I
desire to remove them and to replace them with prune trees. I have been
advised to use dynamite in preparing the soil for the planting of the
new trees.
