Underground Irrigation








How extensively used and with what results is the underground tile
system for irrigation used, and what especial character of soil is it
best suited for?

Not extensively at all; in fact, if there is an acre of it which has
been for three years in continuous and successful operation, it has
escaped us. After forty years of trial of different systems, none has
demonstrated value enough to warrant its use. Theoretically, they are
excellent; in practice they are defective. Surface application in
different ways, according to the nature of the soil, accompanied with
thorough cultivation, is the only thing that at the present time
promises satisfactory results, except that where the land suits it,
irrigation by underflow from ditches on higher elevations is being
successfully used on small areas in the foothills. For gardens the most
promising arrangement seems to be a laying of drain tiles rather near
the surface, which shall be taken up each year, cleaned of silt and
plant roots, and relaid along the rows before planting; but this calls
for too much labor, except perhaps for amateur gardeners. The kind of
soil best suited to such a system is a medium loam which will distribute
water sufficiently to avoid saturation and air-exclusion. Both a heavy
soil which does this, and a coarse sandy loam which takes water down out
of reach of shallow-rooting plants too rapidly and lacks capillarity to
draw it up again, are ill adapted to underground distribution.
