Effects Of Blasting
I have land which is underlaid with hardpan two or three feet deep and
this in turn is underlaid with sand or sandpan. What I would like
to know is whether blasting the holes before setting trees would allow
more moisture coming from this sandpan, or, rather, what effect it would
have as to moisture.
We do not know. It might make the soil better for the trees by allowing
escape for surplus water through previous layers. It might allow the
tree to root more deeply for moisture in those strata. It might allow
water to rise from such strata if they have water under pressure. It
might do other things good or bad, according to conditions prevailing
under the hardpan. If you are to irrigate the land the effects would
probably be good.
