The impact of salinity on greenhouse grown crops, especially when grown in substrate systems, differs from the impact of salinity on crops grown under field conditions. The most striking difference between greenhouse and field conditions is the overall much higher concentrations of nutrients in greenhouse soils and substrates.

Salinity and water deficit [PDF]
, 2020 Drought and salinity are among the environmental factors that constrain citrus productivity most dramatically. The citrus crop is predominantly cultivated in arid and semiarid regions under irrigation conditions, giving rise to problems frequently associated with salt stress rather than water deficit.

Effect of saline water on soil salinity and on water stress, growth, and yield of wheat and potatoes
Agricultural Water Management, 1993Abstract Wheat and potatoes were grown in tanks filled with loam and clay and irrigated with water of three different levels of salinity and, for the wheat, with two irrigation regimes. A combination of soil water sampling and salt balance was used to study the development of soil salinity and the composition of the soil water.

Using a crop-water-salinity production function and a soil-water-salinity dynamic model, optimal irrigation scheduling was developed to maximize net return per irrigated area. Plot and field experiments were used to obtain the crop water sensitivity index, the salinity sensitivity index, and other parameters.

Water Salination: A Source of Energy
Science, 1974The thermodynamically reversible mixing of freshwater and seawater at constant temperature releases free energy. Salination power as a resource is comparable with hydroelectric power in magnitude; U.S. freshwater runoff could yield over 10 10 watts.

The potential of the saline water for irrigation against the background of the world's food shortage is reviewed. It is shown that irrigation has improved food situation wherever it has been used. However, irrigation is always associated with salinity problems. Leaching techniques and drip irrigation suggest a partial solution for the problem.

Continually applying salt-laden irrigation water to soils can lead to soil salinization because plants leave most of the salts behind as they uptake water. Osmotic potential energy in saline soils is negative and resists the movement of water toward plant roots.

Silviculture with Saline Water
1979Mangroves are the trees and shrubs that grow in the edge of the sea and thus are cultivated with saline waters. Their principal product is wood, a renewable resource that substitutes for fossil fuels. Management of mangroves requires little fossil fuel expenditure and mangrove forests produce prawns, finfish and shellfish as byproducts.

Thermodynamics of Saline Water
1971The thermodynamic state of a saline solution is completely specified by the temperature, pressure and chemical potentials of the components that are present. The chemical potential can be defined rigorously in mathematical terms but in this form often provides difficulty in conception. In order to overcome this difficulty for solutions, it is useful to

Crop production in arid and semi-arid regions of the world is dependent upon an adequate supply of suitable-quality water. A supply of water is considered adequate when sufficient quantities are readily available for irrigation throughout the season to meet crop-water needs.
