چکیده
In Golina-Adisalem irrigation scheme, 500 ha becoming salt-affected. Rehabilitation of salt-affected fields using drainage is expensive and leaching by far not feasible in shallow water table areas. The alternative way chemical amendment bioremediation. Therefore, the field experiment was conducted to evaluate possibility gypsum soil halophytic grasses on modification properties saline-sodic soil, their effects infiltration. levels (0%, 75%, 100%, 125% requirement) (Chlorosis Guayana Cynodon Dactaylon) were set factorial RCBD design with three replications. After 2nd harvest, highly significantly (P < 0.01) lowest pHe (7.23, 7.29, 7.51), ECe (4.62, 4.89, 4.31 dS m?1), SAR (10.78, 15.81, 16.38), ESP (8.93, 8.66, 9.47%) recorded from Chlorosis Guayana+125% requirement (G) Dactaylon +125% applied treatment, whereas highest (8.54, 8.77), (20.1, 16.31, 11.431dS (50.12, 54.23, 57.29) (57.37, 66.22, 72.26%) obtained control treatment for 0–20, 20–40, 40–60 cm depths, respectively. reclamation efficiency G statistically equal G. infiltration rates noted soils treated (6.3 cm/hr) Dactaylon+125% (5.92 cm/hr); while value (1.22 treatment. combined application (Rhodes grass massava variety)+125% (Panicum maxima most efficient improving soil.

Stability of a Calcareous Saline-Sodic Soil During Reclamation
General guidelines to reclaim saline or sodic soils do not adequately consider variables such as pH and the presence of organic matter that are known to affect soil stability. Poor structural stability of sodic, saline-sodic, and high-pH soils adversely influences crop yields; promotes piping, tunneling, and slope erosion; and can accelerate the failure of water conveyance systems. We evaluated...

Sodic soil reclamation: Modelling and field study
Reclamation of sodic soils has traditionally been undertaken using calculation of gypsum or Ca requirement assuming 100% exchange efficiency and neglect of the contribution of calcium carbonate in the profile. The UNSATCHEM model is reviewed and then evaluated for its ability to predict field reclamation of a sodic saline soil. The 40-ha field site was initially at an electrical conductivity (E...
