Combating Deterioration in Salt-Affected Soil in Egypt by Crop Rotations

Impact of Some Soil Amendments on Properties and Roductivity of Salt Affected Soils at Kafr El-Sheikh Governorate

“…These results seem to agree with findings observed by Courtney and Harrington (2012) and El-Sanat et al(2017). It could be observed that the application of gypsum combined with compost was more effective on SAR than gypsum only as observed also by Vance et al (1998), Abdel-Fattah & Merwad (2016 ) and Ouda & Zohry (2016). The reduction in soil SAR due to application of compost may be related to release of Ca 2+ from soil CaCo 3 or leaching of Na + from soil (Sarwar et al, 2008).…”

“…These results may be due to during growth stages of rice, the standing water could be disposed through drainage system and replaced with fresh water. This process could reduce the salinity of both soil and ground water (Ouda and Zohry 2016).…”

Feasibility of different crop rotations for cultivation in salt affected soils

“…Crop rotation resulted in several improvements, in soil physical and chemical properties and is also suggested for salt affected soil, especially when crops with varying degrees of salinity tolerance are used (Lacerda et al, 2011). For suitable crop rotation in salt affected soils, selected crop should be either salt tolerant or tolerant cultivars must be selected from sensitive or medium tolerant crops with high economic value (Ouda et al, 2016;Kishk, 2000). Likewise, appropriate crop ro-tation in salt-affected soils can accelerate the reclamation process by reducing evaporation and upward transport of salt in the soil (Brady and Well, 2008).…”
