Soil salinity is the salt content in the soil; ... High levels of soil salinity can be tolerated if salt-tolerant plants are grown. Sensitive crops lose their vigor ...
The salt level is often taken as the soil salinity or the salinity of the irrigation water. Salt tolerance is of importance in irrigated lands in (semi)arid regions where the soil salinity problem can be extensive as a result of the salinization occurring here. It concerns hundreds of millions of hectares. [2]
The desired soil salinity level Cd depends on the crop tolerance to salt. The University of Wyoming, [ 10 ] US, and the Government of Alberta, [ 11 ] Canada, report crop tolerance data. Strip cropping: an alternative
Salinity (/ s ə ˈ l ɪ n ɪ t i /) is the saltiness or amount of salt dissolved in a body of water, called saline water (see also soil salinity). It is usually measured in g/L or g/kg (grams of salt per liter/kilogram of water; the latter is dimensionless and equal to ‰ ).
^) The crop performs well (no yield reduction) up to the soil salinity level listed in the table. Beyond that level, the yield goes down. The main difference with the classification published by Richards in the USDA Agriculture Handbook No. 60, 1954 [4] is that the classes are narrower with steps of 2 dS/m instead of 4.
High levels of salt are often found in dry soils, more so than wet soils as it is diluted and washed through the soil profile. (Barry and Holwell et al., 2012). (Barry and Holwell et al., 2012). Secondary salinity is a direct result of human interaction with the land, during development , agriculture and irrigation.
Again, according to Iversen (1936), these plants are classified with respect to the salinity of the soil on which they grow. [3] Oligo-halophytes (amount of NaCl in the soil is 0.01 to 0.1%) Meso-halophytes (amount of NaCl in the soil is 0.1 to 1%) Euhalophytes (amount of NaCl in the soil is >1%) For comparison, seawater has a
In irrigated agricultural land, waterlogging is often accompanied by soil salinity as waterlogged soils prevent leaching of the salts imported by the irrigation water. From a gardening point of view, waterlogging is the process whereby the soil hardens to the point where neither air nor water can soak through.
