Abstract:

Background The growth and physiological responses to sodicity stress of pear and peach are poorly understood. Insights into how sodicity stress alters tree physiology remain vital to developing salt tolerant scion and rootstock cultivars. Methods The effects of sodicity stress (soil pHs ~8.8) on tree growth and physiological traits of field grown trees of pear cultivars Punjab Beauty and Patharnakh, and peach cultivars Partap and Shan-e-Punjab were recorded using standard procedures. Sodicity-induced changes in oxidative stressors, proline, anti-oxidant enzymes and leaf ions were measured to d

Abstract:

Salinity and sodicity have been a major environmental hazard of the past century since more than 25% of the total land and 33% of the irrigated land globally are affected by salinity and sodicity. Adverse effects of soil salinity and sodicity include inhibited crop growth, waterlogging issues, groundwater contamination, loss in soil fertility and other associated secondary impacts on dependent ecosystems. Salinity and sodicity also have an enormous impact on food security since a substantial portion of the world’s irrigated land is affected by them. While the intrinsic nature of the soil could

Abstract:

The productivity of irrigated agriculture in Australia is low for most crops and one important factor is the physical and chemical constraints caused by sodicity in the rootzone. Over 80% of the irrigated soils are sodic and have degraded structure limiting water and gas transport and root growth. Irrigation, without appropriate drainage, leads to the buildup of salts in soil solutions with increased sodium adsorption ratio (SAR) and can develop perched watertables due to a very low leaching fraction of the soil layers exacerbated by sodicity. Therefore, irrigation management in Australia is c

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 on sodic soils. The largest sodicity class is 'alkaline sodic', dominated by a diverse range of soils (red duplex, yellow duplex, calcareous earths and self-mulching cracking clays).

Abstract:

Sodic soils are characterised by their poor structural stability. This is thought to be caused mainly by high levels of exchangeable sodium and low electrolyte concentrations. Historically, soil sodicity has been reported as the exchangeable sodium percentage, ESP [(exchangeable Na/∑ exchangeable cations)�×�100]. However, some authors believe that exchangeable sodium content alone is a better indicator of sodicity, whereas others suggest that an effective sodicity index is one which includes both the exchangeable sodium levels and electrolyte concentration (EC1:5).

Lucerne plots were irrigated with waters of electrical conductivity (EC) = 0.1, 0.8, 2.5, 4.5 and 7.5 dS/m for the summers of 1991–92 to 1994–95. Within those 4 years, soils were sodified at irrigation treatment salinities greater than 0.8 dS/m. Subsequent leaching of salts with channel water (EC = 0.1 dS/m) and rain water (1995–97) reduced surface soil sodicity but not subsoil sodicity. This resulted in increased dispersed clay in the subsoil. Clay dispersion was best explained by exchangeable sodium percentage (ESP) and Mg in topsoils, and by ESP and salinity (TCC or Cl) in subsoils. Ponding

Abstract:

Salinity and sodicity are the major abiotic constraints that prevail in arid and semi-arid regions. Proper management is required for productive use of this land. Reclamation of sodic and saline-sodic soils is highly site-specific that describes the diverse response of different soils to different amendments. These reclamation practices also alter the plant's physiological and ionic characteristics. This experiment aimed to better understand the physiological and ionic responses of rice crop at different salinity/sodicity levels. A lysimeter experiment was set forth with soil having ECe (dS m-

Abstract:

Soil salinity and sodicity are two of the most limiting constraints for agriculture in arid and semiarid landscapes, but long-term studies are scarce, and most solely focus on the topsoil. This study monitors the change in soil electrical conductivity (EC) and exchangeable sodium percentage (ESP) to 1.2 m depth with bivariate linear mixed models between 2002 and 2015 in a semiarid, irrigated cotton-growing region of south-west New South Wales, Australia. In this work, the impacts of shifts in rainfall, variability of irrigation water quantity and quality, and agricultural land uses, on soil sa

Abstract:

Accurate data on the distribution of the various types of sodic soils in New South Wales are not available. However, general observations suggest that large areas are affected by structural instability as a result of sodicity, particularly on grey clays and red-brown earths of the Murray-Darling Basin. There is a strong need for new sodicity surveys because the production of crops and pasture often is well below potential on these lands. Exchangeable sodium data on their own do not adequately describe sodic soil behaviour, so information is also required about related factors such as electrica

Abstract:

Knowledge of spatiotemporal distribution and likelihood of (re)occurrence of salt-affected soils is crucial to our understanding of land degradation and for planning effective remediation strategies in face of future climatic uncertainties. However, conventional methods used for tracking the variability of soil salinity/sodicity are extensively localized, making predictions on a global scale difficult. Here, we employ machine-learning techniques and a comprehensive set of climatic, topographic, soil, and remote sensing data to develop models capable of making predictions of soil salinity (expr

Abstract:

Irrigation-induced salinity is a serious problem facing irrigated areas in the Murray–Darling Basin of Australia. Groundwater pumping with farm re-use for irrigation is a key strategy for controlling salinity in these irrigation areas. However, the re-use of highly saline–sodic groundwater for irrigation leads to accumulation of sodium in the soil profile and can result in sodic soils. Leaching of saline–sodic soils by winter rainfall and low salinity irrigation waters are 2 management scenarios likely to exacerbate sodicity problems. Characteristic to sodic soils is poor soil structure and po

This paper briefly summarizes existing Australian data about causes of sodicity and the distribution of sodic soils in Australia. Sources of salts and sodium include atmospheric accession, salts released by weathering processes and saline groundwaters. A traditional model of sodic soil pedogenesis is contrasted with more recent data demonstrating the role of several factors including mineralogy, EC/ESP relationships and exchangeable magnesium percentage on development and behaviour of sodic soils. Limited data about the national distribution of sodic soils are presented. There has been very li

Abstract:

Studies were conducted in the 1950s to evaluate the degree and spatial extent of soil salinity and sodicity in the Lajas Valley in southwestern Puerto Rico. Problem areas were identified and most of these were remediated with the establishment of irrigation and drainage infrastructure, resulting in a four-fold increase in agricultural production over a 10-year period. The area is now an important agricultural region (known as the Lajas Valley Agricultural Reserve). But soil salinity and sodicity are important concerns among farmers. In this paper we used published data and re-created the spati

Abstract:

Irrigation with sodic waters may damage soil structure, but neither the processes involved nor the critical levels of exchangeable Na have been well defined for prairie soils. We examined two irrigated soils from southern Saskatchewan on which sodicity damage had occurred to determine the processes and the chemical conditions (exchangeable Na and electrolyte concentration) that cause structural damage. Dispersion of clays in the upper 20 cm of the profile seemed to be the primary cause of structural deterioration. Examination of irrigated soil by scanning electron microscopy (SEM) showed that

The effects of sodium (Na+), calcium (Ca2+), magnesium (Mg2+), and boron (B) concentrations and sodicity, as measured by the sodium adsorption ratio (SAR), on the growth of a Rhizobium leguminosarum bv. viceae strain isolated from a salt-affected soil were studied. The rate of growth was measured in a yeast extract - mannitol broth, amended with salts having electrical conductivity (EC) of 4, 8, and 16 dS·m-1. Each salinity level was prepared to achieve SAR values of 10, 20, and 30 with or without graded B concentrations of 0.5, 1, 3, and 5 mg·L-1. We found that salinity levels equal to or mor
