SODiCS on Challenged Communication Environment
2014 Eighth International Conference on Innovative Mobile and Internet Services in Ubiquitous Computing, 2014Through we experienced at the Eastern Japan Great Earthquake on March 11, 2011, a disaster information gathering systems are strongly needed to widely collect the disaster state around the evaluated areas, correctly analyze the degree of damages and quickly make decision of disaster recovery response.

How do sodic soils behave - the effects of sodicity on soil physical behavior
Australian Journal of Soil Research, 1993A model has been presented to illustrate the way in which the influence of exchangeable Na on the fundamental processes of dispersion and flocculation on Na-Ca systems affects the various soil physical properties in the field. Most cultivated soils slake (breakdown into microaggregates) when subjected to rapid wetting, giving rise to a surface seal and

Sodic soils are widespread in Australia reflecting the predominance of sodium chloride in groundwaters and soil solutions. Sodic soils are subject to severe structural degradation and restrict plant performance through poor soil-water and soil-air relations.

This paper gives a broad overview of the distribution and agricultural importance of sodic soils in Victoria. Sodic soils are estimated to occupy at least 13.4 Mha, representing at least 73% of Victoria's agricultural land. Most of this land is used for dryland farming; about 85% of the cropped land and 66% of the land sown to dryland pastures occurs ...

Use of an electromagnetic technique to determine sodicity in saline‐sodic soils
Soil Use and Management, 2007Abstract Soil sodicity is an increasing problem in arid‐land irrigated soils that decreases soil permeability and crop production and increases soil erosion. The first step towards the control of sodic soils is the accurate diagnosis of the severity and spatial extent of the problem.

EFFECT OF DRIP IRRIGATION ON COTTON USING SODIC WATER IN SODIC SOIL.
Madras Agricultural Journal, 1993A study was conducted to find out the efficacy of drip irrigation, in combination with row spacing and plant spacing on the yield of MCU 7 summer cotton. Two levels of irrigation, three levels of row spacing and three levels of plant spacing were incorporated in the study. The water used for irrigation and the field soil type were sodic.

The objective in reclaiming sodic soils is to ameliorate undesirable physical conditions such as surface crusting and low hydraulic conductivity which impede infiltration, water storage, seedling emergence and root development. These undesirable physical characteristics result from enhancement, by exchangeable sodium, of clay swelling, dispersion, and ...

According to different estimates, there are 831 to 932 million hectares of salt affected soils – saline soils, saline-sodic soils and sodic soils. The measure of salinity is the electrical conductivity of the saturation extract (ECe) and the measure of sodicity is the exchangeable sodium percentage (ESP) or the sodium adsorption ratio (SAR).

Sodicity and soil microstructure [PDF]
Clay domains are the operational particles in clay soils and their properties can be used as a model with which to interpret soil physical behaviour. The experiments conducted for this thesis were designed to use the proportion of exchangeable sodium on the clay surfaces (sodicity), electrolyte concentration, and mechanical action as tools to examine ...
