“…As a result, several studies found an increase in soil sodicity when irrigation was conducted with TWW (e.g.. Balks et al, 1998;Halliwell et al, 2001;Gharaibeh et al, 2007;Mandai et al, 2008). In the present work, we observed that this effect varied according to the soil type.…”

“…In California and much of the Western United States, agricultural drainage and municipal treated waste water, termed as 'reclaimed water', are used mainly for agricultural irrigation to supplement the scarcity of fresh canal water and as an alternative for their disposal (Mandal et al, 2008;Wu et al, 2009). The chemical characteristics that determine the suitability of these marginal quality waters for irrigation are same as those of fresh waters given by Ayers and Westcot (1985).…”

a b s t r a c tRemediating saline-sodic soils with organic amendments is increasingly seen as a cheaper and sustainable alternative to inorganic materials. The reclamation potential of biochar, biosolids and greenwaste composts applied to a saline-sodic soil was evaluated in a laboratory leaching experiment using moderate SAR reclaimed water. Treatments included biochar, biosolids co-compost, greenwaste compost (all applied at a 75 t ha −1 rate), gypsum (50% soil gypsum requirement), biochar + gypsum, biosolids + gypsum, greenwaste + gypsum and a non-amended control. All treatments were subjected to a one month incubation after which, soils were filled in columns and leached using reclaimed water until 7 PV of water had passed. Cumulative leachate losses of Na + , Ca 2+ , and Mg 2+ were evaluated in addition to soil properties after leaching. Results show that leaching with moderate SAR water was effective in reducing the soil salinity and sodicity of all soils, irrespective of amendment application. However, incorporating biochar and composts significantly enhanced this effect. Salt leaching was higher in soils treated with organic amendments. Cumulative leachate losses of cations were significantly higher from biochar and compost treated soils compared to gypsum and unamended controls. Improvements in soil aggregate stability and saturated hydraulic conductivity were prominent in compost treated soils. After leaching, soil analyses indicated that organic amendments lowered significantly more soil EC e , ESP and SAR than that of the control soils and saturated the exchange complex with Ca 2+ . Soil pH was significantly reduced and CEC was significantly increased in only compost treated soils. Although individual organic amendment applications proved to be significant enough to remediate a saline-sodic soil, combined applications of gypsum and organic amendments were more effective in improving soil properties directly related to sodium removal including sodium leaching, hydraulic conductivity, ESP, and SAR, and therefore could have a supplementary benefit of accelerating the reclamation process.

“…resources, and agricultural production, several authors have studied the effects of effluent irrigation on the soil chemical and physical properties (Levy et al, 1986;Balks et al, 1998;Halliwell et al, 2001;Ben-Hur, 2004;Dawes and Goonetilleke, 2006;Heidarpour et al, 2007), including soil hydraulic properties (Rice, 1974;Vinten et al, 1983;Cook et al, 1994;Levy et al, 1999;Tarchitzky et al, 1999;Magesan et al, 1999Magesan et al, , 2000Mamedov et al, 2000Mamedov et al, , 2001Ben-Hur and Assouline, 2002;Agassi et al, 2003;Lado et al, 2005;Gloaguen et al, 2006;Gharaibeh et al, 2007;Bhardwaj et al, 2007Bhardwaj et al, , 2008Mandal et al, 2008). Several mechanisms have been hypothesized to cause changes in soil hydraulic properties when effluent is used for irrigation.…”
