Infiltration rates into furrows in southcentral Idaho,
after decreasing toward a base rate, sometimes
increase. The increase is sometimes sufficient to cause
tailwater runoff to cease and the furrow stream to recede
up the furrow, resulting in poor water distribution. The
infiltration increase is caused by earthworms piercing the
furrow wetted perimeter during the irrigation allowing
water to enter and infiltrate from their extensive burrow
system. Low concentrations of aqua ammonia in the
irrigation water prevent the infiltration increase,
apparently by repelling the worms from the furrows.
