Difference between Saline and Sodic Soils: Saline soil is a term used to describe excessive levels of soluble salts in the soil water (soil solution), high enough to negatively affect plant growth, resulting in reduced crop yields and even plant death under severe conditions (Figure 1). Figure 1. A typical saline spot along state Highway
Coastal saline areas are normally monocropped with rice grown during the wet season. On-farm trials were conducted in Ersama block of Jagatsinghpur district, Orissa, India, during to evaluate the performance of selected non-rice crops in the coastal saline ecosystem during the dry season. In , sunflower, Basella, watermelon, chilli, pumpkin, groundnut, tomato, bitter gourd and. The pH of saline soils is generally below The normal desired range is to , but many Texas soils are naturally to Leaching the salts from these soils does not increase the pH of saline soils. Saline-sodic soils. Saline-sodic soils are like saline soils, except that they have significantly higher concentrations of sodium.
Soil salinity is caused by several factors. Soils may become saline as a result of land use, including the use of irrigation water with high levels of salt. Seawater is also a source of salts in low-lying areas along the coast through tidal estuaries or when rainfall in coastal . Improving rice productivity in the coastal saline soils of the Mahanadi Delta of India through integrated nutrient management. The coastal saline belt of the Mahanadi Delta in Orissa, India, is mostly monocropped with rainfed rice during the wet season (WS). In the dry season (DS), a small area is planted to rice using harvested rainwater.

These soils can be reclaimed by improving drainage, by applying gypsum and/or lime, and by cultivating salt resistant crops like barseem, dhaincha and other leguminous crops. The saline and alkaline soils may occur in any group of soils. Crops grown: In coastal areas, coconut trees are found in plenty in these soils.
As discussed above. Coastal saline Soils of India: A review. Coastal region covers a long strip along the east coast (West Bengal, Orissa, Andhra Pradesh, Pondicherry and Tamil Nadu) and west coast (Gujarat, Maharashtra, Karnataka and Kerala).
Salinity is mainly due to the presence of saline ground water at shallow depth and frequent sea water inundation in the Author: V.
Sabareshwari, A. Ramya. Salinity is most widespread in coastal areas, while saline–sodic soils are more spread in inlands but also occur in coastal areas. The estimates of saline and/or sodic soils are at 9–12 Mha [ Mha in India (Maji et al., ); 1 Mha each in Bangladesh, Thailand, and Vietnam; and 1 Mha in Myanmar and Indonesia combined] (Bouman et al., ).

'Diagnosis and Improvement of Saline Alkali Soils' (USDA Hand book No. Washington, DC, USA). Soil Survey Staff (). The coastal soils are alluvial and partially saline with sporadic patches of saline-alkali, non-saline alkali and degraded alkali soils.
The soil pH varies from In patches lower pH even below are also recorded which suggest the presence of acid sulphate soils as well as muck soils. Rice has long been grown in the coastal regions of India and other countries where salinity is a perpetual problem due to inundations from the sea, and intrusion of sea water through rivers, estuaries, etc.
Screening of a large range of rice germ plasm collected at different saline areas in India led to the identification of several genotypes. Salt affected soils exist across the length and breadth of India covering 16 states/union territories; the maximum salt affected soils are in Gujarat ( m ha) followed by Uttar Pradesh ( m ha).
Saline soils can be easily reclaimed by application of sufficient water to promote leaching of salts beyond the root zone.
Sodic soils are often referred to as “black alkali” or “slick spots” because of the dissolved organic matter in the soil solution. Sodic soils are characterized by the following: EC. Most of them have been field tested successfully in saline soils in Satkhira, a coastal district in southwestern Bangladesh (CCC, ).
In general, soil salinity in Satkhira may be classified into four levels, ranging from low (15 dS/m) (Table ). Introduction. Salinity is a serious threat to world agriculture. In India, out of an estimated area of mha of total degraded land, mha are salt affected, and out of which mha are in the coastal regions .The soil salinity in coastal regions of Gangetic delta in West Bengal shows wide spatial and seasonal variability, being minimum during monsoon and maximum during summer.
Acid saline soils Acid saline soils are present throughout the coastal area in patches with very little extent. Major area of this soil is identified in the coastal tract of Ernakulam, Thrissur and Kannur districts.
The area under these soils comprise of low-lying marshes, waterlogged and ill drained areas near the rivers and streams, which are. Semi-arid Indo-Gangetic alluvial tract (Punjab, Haryana, UP, Delhi, parts of Bihar) 2.

Following the description of coastal morphology and the Indian shoreline, the causes of salinity and the characteristics of the coastal salt-affected soils of India are discussed.
The management of coastal saline soils and of coastal acid sulfate soils is then considered, and the. The highly saline soils on the soil salinity map are confined to the coastal land (King et al.
), the areas of deflation plains, and inland sabkha (salt scald) where the groundwater levels approach the surface, creating large areas of aquisalids at the great group level of US soil taxonomy (Soil Survey Staff ; Shahid et al. Soil salinity is the salt content in the soil; the process of increasing the salt content is known as salinization.
Salts occur naturally within soils and water. Salination can be caused by natural processes such as mineral weathering or by the gradual withdrawal of an ocean. It can also come about through artificial processes such as irrigation and road salt.
Coastal, India, Paddy, Rice, Saline soils, Salt-tolerant. 1. Introduction Rice (Oryza sativa L.), belonging to the family Gramineae, is a primary source of food for more than half of the world population.
It is planted on about one-tenth of the earth’s arable land in.When soluble salts (from saline-alkali soils) are removed by leaching as a result of the increase in rainfall, it gives rise to non- saline-alkali soil (only Na-clay in the soil colloids).
Calcium carbonate (CaCO 3) reacts with Na-clay and give rise to Ca-clay and sodium carbonate (Na 2 CO 3).Coastal saline Soils of India: A review V. Sabareshwari*1 and A. Ramya Department of Environmental Science, Tamil Nadu Agricultural University, CoimbatoreTamil Nadu, India.
