Soil correction is one of the ways in agriculture lands development. The sodic ion alongside salin vocalizes the salin-sodic soil and cause divulge in plants growth. So necessary coure of action for the Soil correction by physical and chemical ways such as usage of calsium on the leaching is inevitable. In this study, area soils are digged from deep profiles of 0-20, 20-40, 40-60, 60-80 and 80-...
The study site is a typical, perched wetland in a saline, sulfidic discharge area in the eastern Mt Lofty Ranges near Adelaide, South Australia. The wetland is part of the 10% of strongly waterlogged landscape identified by GIS analysis of a larger 80 km area. Approximately 40% of this area was identified as being poorly drained, but only a small proportion, less than 10%, supports wetland vege...
This study was conducted to assess the influences of soil surface conditions and initial soil water content on water movement in unsaturated sodic soils of reclaimed coastal areas. Data was collected from column experiments in which two soils from a Chinese coastal area reclaimed in 2007 (Soil A, saline) and 1960 (Soil B, nonsaline) were used, with bulk densities of 1.4 or 1.5 g/cm(3). A 1D-inf...
the main limiting factors in saline-sodic soils are high amounts of salts, low soil organic matter (som) and lowavailability of macro and micro-nutrients. the effect of different amounts of nano iron oxide powder and urban solidwaste compost coated sulfur (uswcs) on the chemical properties of a saline-sodic soil was investigated. the experimentwas conducted using a randomized complete block des...

Soil salinization and sodification are common processes that particularly characterize drylands. These can be attributed either to natural conditions or anthropogenic activities. While causes include factors such as climate, lithology, topography, pedology, human mostly related agricultural land-use, specifically, irrigated agriculture. The objective of this study was thoroughly review topic, w...
The reclamation of salt-affected soils which occur on 831×106 ha can be effective in increasing agricultural production. Cultivation of plant species which are resistant to salinity can improve the soil by increasing the solubility of calcite and releasing the calcium in soil solution. This study was conducted as a column experiment with a saline-sodic soil (SAR = 23.8, EC= 12.88 dS m-1, pH= 7....
Reclaimed tidelands (RTLs) in the southwestern coastal areas of South Korea has been used for rice (Oryza sativa L.) cultivation due to high salinity soils. However, there is increased social pressure utilize RTLs upland crop decreased consumption. In this study, and sodicity 16 located were investigated explore suitability cultivation. Surface (0 - 20 cm) soil samples collected from 241 paddy ...
