摘要

A field experiment was carried out to evaluate the changes in some physicochemical and fertility properties of sandy loam soil treated with three different rates of humic acid (HA) under three different irrigation water regimes. Soil bulk density and saturated hydraulic conductivity were decreased while organic matter was increased by increasing HA rates. Decreasing water regime and increasing HA rate increased soil salinity. Decreasing irrigation water regime increased nitrogen and reduced available phosphorus and potassium. Increasing HA rate increased nitrogen and available phosphorus and potassium.
