Physical Properties of Sandy Soil Affected by Soil Conditioner Under Wetting and Drying cycles

M.I. Choudhary, A.M. AI-Omran, A. A. Shalaby · Journal of Agricultural and Marine Sciences · 1998 · 10.24200/jams.vol3iss2pp69-74

Information on the effectiveness of soil conditioners over a prolonged period is scarce. A laboratory experiment was undertaken to evaluate the effectiveness of a polyacrylamide (Broadleaf P4) soil conditioner on the physical properties of sandy soil subjected to wetting and drying cycles. Four concentrations of Broadl …

Impact of Sewage Sludge on Water Movement in Calcareous Sandy Soils

A.M. AI-Omran, M.I. AI-Wabel, A. A. Shalaby · Journal of Agricultural and Marine Sciences · 1997 · 10.24200/jams.vol2iss0pp59-67

The present study was undertaken to investigate the changes in soil physical properties and their effect on water movement under ponded irrigation. Sewage sludge was applied to 10 cm soil depth at rates of 0.25. 75 and 100 Mg-ha-1 to two disturbed soils differing in CaCO3 content. The results showed that cumulative inf …
