Abstract

Past nitrate leaching concerns from permeable furrow-irrigated
soils were more for nutrient utilization inefficiency than
groundwater contamination. Systematic variation occurs in
infiltration, saturated flow, equipotentials, and solute movement
with furrow irrigation (2, 3). Saturated flow near furrows
can leach water and NO3-N beyond the root zone
(Figure 1). Sprinkler and furrow irrigation comparisons confirmed
NO3-N leaching losses with furrow irrigation even
without over-irrigation (8).
