Agriculture can also contribute to soil salinization through the use of fertilizers. This process has happened in many places throughout the world, famously in Ancient Greece and Ancient Mesopotamia. Someone gives you two sets of coins. As plant roots uptake water through osmosis, dissolved salts enter the plant. In addition, measures to prevent or reverse soil salinization can be expensive. The major soil salinity effect on plant growth is tampering with water absorption. When the salt concentration is too high, it means that the soils osmotic potential is essentially negative. __________ is an example of desertification. Strong water currents ruin constructions, damage farmlands, increase sedimentation, and contaminate aquatic bodies. Many agricultural development projects are aimed at implementing water drainage systems to flush out salts, but they often require a great deal of funding and labor.

Over time, soil salinization can have detrimental effects on plants and soil structural properties, which disrupts agriculture and contributes to food shortages. The best way to deal with soil salinization is not to let it happen. The existing time-lag between occurrence and recording of various data is also suggested to improve in the future scenario by the usage of information from multiple satellites that lessens the problems of spatial resolution by increasing the system efficiency. With a rise of salt concentration in the solution, its conductivity rises, too. increasing the economic value of a commodity through particular production processes, e.g., organic produce, or through regionally branded products that increase consumer appeal and willingness to pay a premium over similar but undifferentiated products. Coastal areas are very prone to soil salinization due to flooding. Soil salinization has negative impacts on plant health and soil structure, and it can bring about many concomitant socioeconomic problems. In addition, rain water typically contains low amounts of dissolved salts, but irrigated water can contain much higher salt concentrations. Similar to the removal of vegetation, irrigation can cause groundwater levels to rise above natural levels, bringing once buried salts up to the topsoil. In 2001, he successfully defended a thesis, Substantiation of Agroecological Conformity of Models of Soil Fertility and its Factors to the Requirements of Field Cultures and obtained the degree of Biosciences Candidate with a special emphasis on soil science from the NSC Institute for Soil Science and Agrochemistry Research named after O.N.
