Soil salinity/sodicity is the major problem in irrigated and rain-fed areas are a continuous threat for sustainability of agricultural production. The presence salt affected soils has been identified as process land degradation greatest cause declining productivity by causing detrimental effect on biological, physical chemical properties soil system. Therefore, objective this topic to review im...

A lot of salt-affected soils in the world are also affected by compaction and waterlogging due to shallow water tables or decreased infiltration sodicity. Waterlogging cause reduced oxygen exchange (hypoxia). Research on combined impacts salinity hypoxia turfgrass growth is limited. The interactive effects availability nine perennial ryegrass entries (Lolium perenne L.) one alkaligrass [Puccine...

This research aimed to assess the impact of deep ploughing, with manuring and alone, as well effects different calcium ameliorants on physicochemical properties, fertility, crop productivity calcic chernozems in Northern Steppe Ukraine over a period 7 years. Deep ploughing manure had long-term positive mentioned characteristics that were irrigated brackish water long period. The bulk density de...

Salt-affected soils are related to salinity (high content of soluble salts) and/or sodicity (excess sodium), which major leading causes agricultural land degradation. This study aimed evaluate the performances three machine learning (ML) algorithms in predicting soil exchangeable sodium percentage (ESP), electrical conductivity (ECe), and salt-affected classes, from salt ions. The assessed ML m...

The objectives of this study were to investigate the degree of spatial variability and variance structure of salinization parameters using classical and geostatistical method in Songnen Plain of China, which is one of largest saline-sodic areas in the World, and to analyze the relationship between salinization parameters, including soil salinity content (SC), electrical conductivity (EC), sodiu...

Land use-land cover change and management practices influence earthworm species composition and abundance. The natural and agroecosystems under study in the Indogangetic region have a depauperate earthworm fauna. This study provides evidence that agriculture intensification and soil sodicity can severely influence earthworm diversity, in which natural and less disturbed ecosystems had lower ear...

Salinisation is the accumulation of water-soluble salts in the soil solum or regolith to a level that impacts on agricultural production, environmental health and economic welfare. Salt-affected soils occur in more than a hundred countries of the world with a variety of extents, nature and properties. No climatic zone in the world is free from salinisation, although the general perception is fo...
