Despite the trend towards
center pivot and drip irrigation,
furrow irrigation is
still used on almost half of the
irrigated land in the US.
However, soil erosion is an
inherent problem when water
flows over soil. Erosion causes
problems within the field and off
the field. Within a field, soil
tends to erode from the upper
end making furrows deeper.
Erosion deposits soil on the bottom
end, filling furrows and
causing water to flood across
rows. Severe erosion can expose
plant roots. Fortunately, applying
a small amount of polyacrylamide
(PAM) to the furrow soil
or with irrigation water almost
eliminates erosion in irrigation
