  A study of the distribution pattern of sodic lands in canal and noncanal command areas in a reclamation site (covering 60 villages out of which sodic lands were mapped in 51 villages) of Etah district in Uttar Pradesh, indicates that per cent area of the canal command villages was barren sodic which was per cent of the total Cited by: 2. soils that impair salt and nutrient movements and root penetration. An area of ha (%) is salt affected in Kaithal district, of which sodic and saline soils covered ha (%) and ha (4%), respectively. The groundwater quality was sodic in north of Kaithal district (Guhla block),File Size: KB. Out of lakh ha of the area, lakh ha is affected by various soil degradation problems, like droughty soils, flooding hazard and salinity and alkalinity . In general, an EC e of 4 dS m − 1 is used as the boundary between saline and nonsaline soils; the soils of higher EC e are called saline. Actually, salt sensitive plants are affected at half of this salinity (2 dS m − 1)and highly tolerant plants at about twice of .

The following points highlight the three main types of salt affected soils. The types are: 1. Saline Soil 2. Sodic Soils 3. Saline-Sodic Soil. Type # 1. Saline Soil: Soil that contains sufficient soluble salts to impair its productivity is known as saline soils, also called as Solonchak. Of the then million ha of irrigated land, 45 million ha ( percent) were salt-affected soils; and of the almost 1 million ha of dryland agriculture, 32 million ( percent) were salt-affected soils as indicated in the below table. Figures included arable and non arable soils. Soil Scientist, NRCS 25½ West 6th Ave Redfield, SD () , ext. 4 jame @ The abundance of precipitation in the ’s has increased the number and extent of salt affected soils in South Dakota. Many of these salt affected soils started in the middle ’s as small isolated areas that had limited crop yield. About Salt-Affected Soils. Salt is a naturally occurring element in soil. Although small amounts of salt are not harmful, high levels of salt can harm soil structure and make the soil inhospitable.

Soils high in salinity and sodicity have high values of ECe, ESP, SAR, and pH. Salt-affected soils generally suffer from deficiencies of nitrogen (N), phosphorus (P), and potassium (K). However, their high pH also adversely affects the availability of micronutrients such as Fe, Al, Zn, Mn, and Cu. Heavy rainfall occurs waterlogging, which enhances soil salinity due to the higher Na+ conc.
