Furrow irrigation is an effective means of applying
water to a crop. Unfortunately, it can also be
effective in removing topsoil.
Annual soil losses on furrow-irrigated fields can
average from almost nothing on a nearly level alfalfa
field to 30 tons an acre on sugarbeet fields with
more than a 2 percent slope. Thirty tons of soil is
almost 25 cubic yards.
A 30-ton per acre yearly soil loss adds up to 1 inch
of topsoil lost every 5 years. Put another way, erosion
can haul away 40 pickup loads of topsoil from
each acre in one season.
