Spatial and Seasonal Variation of Furrow Infiltration

Infiltration was measured with a newly developed flow‐through infiltrometer at 20–27 sites in a 21 ha (52‐acre) cotton field in the northern region of the San Joaquin Valley of California. The results were comparable with infiltration measured with a neutron probe. The infiltrometer allowed water to flow through the infiltrometer when a rate test was not being conducted. Furthermore, the water level and quality inside the infiltrometer was the...
