| Sprinkler irrigation alters soil hydraulic properties both at and below the soil surface, yet its effects are not well characterized. We evaluated the effects of sprinkler irrigation on infiltration and near‐surface hydraulic conductivity (K) measured under tension in a poorly structured, recently roller‐harrowed Portneuf silt loam (Durinodic Xeric Haplocalcid). The experimental design was a randomized complete block with two treatments (pre‐ and post‐irrigation) and four replications. We used two half‐circle spray heads to apply 127 mm of water at 70 mm h-1 in one irrigation to duplicate 1 × 2 m plots. Unconfined (three‐dimensional) infiltration rates at steady‐state were measured at potentials of -55, -35, and -15mm of water before and about 10 days... |
