Residue management to reduce furrow erosion

D. E. Miller; J. S. Aarstad

ABSTRACT:

Controlled streams were applied to irrigation furrows containing various amounts of plant residue. Infiltration rates, sediment discharge, turbidity of runoff water, and seasonal erosion were measured. The results showed that residue in irrigation furrows controls erosion and reduces turbidity of runoff water. Because relatively small amounts of residue effectively reduced erosion, limited tillage can be used to prepare a seedbed and incorporate herbicides. Sufficient residue will remain to control erosion.
