Heightened water levels also prevent the removal of salts through drainage leaching. Even with sufficient soil moisture, crops wade and die due to the inability to take up enough water. Soil salinization can be prevented by implementing drainage systems that allow for excess salts to be leached out of the soil. Thus, if you are not sure content located Also, previous studies have scarcely incorporated economic, social, and environmental aspects of the salinization problem altogether in their analysis.

Because salts are water-soluble, they can enter into soil environments through groundwater, flooding, or irrigation.2 Salts may accumulate in soil for a variety of reasons, all of which relate to some disruption in water and water-soluble salt dynamics. Declines in productivity may be the result of climate change, deforestation, overgrazing, poverty, political instability, unsustainable irrigation practices, or combinations of these factors. Write the letter of your answer in the space provided. Soil salinization causes include: Salinization can be noticed visually by analyzing the soil surface, speed of water infiltration, and vegetation state. Many farmers in southwestern states have implemented drainage systems to help flush some of these salts away. Purchasing food from nearby farms because you want to minimize the pollution created from the transportation of food around the world. Salcedo FP, Cutillas PP, Cabaero JJA, Vivaldi AG. Shallow-rooted plants may not reach subsoil moisture, and extra subsoil moisture may induce salinity. Subjects. This and all other salts are molecules formed by an ionic bond between a positively and negatively charged ion. Which of the following regions has the highest percentage of land affected by desertification? Soil salinization decreases the osmotic potential of plant roots. Desertification is a growing problem in the world today. As plant roots uptake water through osmosis, dissolved salts enter the plant.

It is most common in densely populated areas of the world where large-scale farming has been common for a long period of time. However, heavy contamination leads to complete loss of farmlands and desertification due to the negative effect of salinity on soil properties. Saline earths show lower agricultural productivity, worsen farmers' wellbeing, and the economic situation in the region. Nearly 74% of North America's drylands are affected by desertification. Send your complaint to our designated agent at: Charles Cohn Between 1950 and 1990, wheat production in India in average pounds per acre more than tripled, which allowed India to meet its population's need for food.
