Normally, the salinization of agricultural land affects a considerable area of 20% to 30% in irrigation projects. When the agriculture in such a fraction of the land is abandoned, a new salt and water balance is attained, a new equilibrium is reached and the situation becomes stable.
Soil salinity is the salt content in the soil; the process of increasing the salt content is known as salinization. [1] 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.
to mitigate the adverse effects of shallow water tables and soil salinization, some form of watertable control, soil salinity control, drainage and drainage system is needed as drainage water moves through the soil profile, it may dissolve nutrients (either fertilizer-based or naturally occurring) such as nitrates, leading to a buildup of those ...
Freshwater salinization can negatively effect the species richness, diversity, and community composition across multiple trophic levels. Competitive interactions between zooplankton can change as salinity increases, leading species such as Simocephalus vetulus to outcompete the normally-dominant Daphnia galeata under high salinity treatments ...
It does not provide a sharp tolerance level. Using the Maas–Hoffman model in situations with a flat trend in the tail-end may lead to a breakpoint with a low ECe value, owing to the employment of the condition to minimize the deviations of the model values from the observed values over the entire domain (i.e. including the tail-end).

Windbreaks are sufficiently dense rows of trees at the windward exposure of an agricultural field subject to wind erosion. [7] Evergreen species provide year-round protection; however, as long as foliage is present in the seasons of bare soil surfaces, the effect of deciduous trees may be adequate.
In agriculture, depletion can be due to excessively intense cultivation and inadequate soil management. Depletion may occur through a variety of other effects, including overtillage (which damages soil structure), underuse of nutrient inputs which leads to mining of the soil nutrient bank, and salinization of soil.
