Soil salinization can be prevented by implementing drainage systems that allow for excess salts to be leached out of the soil. Sign up to highlight and take notes. How does salinization occur in agriculture? Copyright 2020 Elsevier Ltd. All rights reserved. PDF AP Environmental Science Scoring Guidelines, 2016 LAND COVER CHANGE: process by which agricultural areas are lost to development. Developing. Water table rise due to salinization reduces the earths ability for water infiltration. For example, slight whitening on the surface changes into distinct salt crystals. . The .gov means its official. Let's look at some examples of soil salinization: The Nile River Delta has served as Egypt's cradle of agriculture for thousands of years. A valley and early civilization along the Indus River, one of the longest rivers in the world. This paper provides a comprehensive review of different measures used for managing the environmental problems of soil salinization. Send your complaint to our designated agent at: Charles Cohn The time when human beings first domesticated plants and animals and no longer relied entirely on hunting and gathering. What is the leading cause of global soil salinization? At a global span, according to the report of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) of 2018: Soil salinization occurs when soluble salts are retained in the earth. Soil salinization is most common in arid and semi-arid climates, as well as coastal areas. "Salinization" occurs when soil in an arid climate has been made available for agricultural production using irrigation. on or linked-to by the Website infringes your copyright, you should consider first contacting an attorney. J Environ Sci Health A Tox Hazard Subst Environ Eng. We'll assume you're ok with this, but you can opt-out if you wish. However, heavy contamination leads to complete loss of farmlands and desertification due to the negative effect of salinity on soil properties. Remove salt crystals from the surface mechanically. How does capillary action contribute to soil salinization? A. fertilization and salinization B. pesticides and fertilization C. salinization and topsoil loss D. topsoil loss and gentrification E. the Green Revolution and agribusiness Humans drain wetlands to create fields and pastures, the property whereby long-run average total production cost falls as the quantity of output increases, goods or services sold to a foreign country, farming practices that involve putting relatively little energy into the land for the calories extracted. The problem with salinization is that salts not only accumulate in earths but penetrate to initially fresh water bodies as well, leading to their salinization. The small scale production of fruits, vegetables, and flowers as cash crops sold directly to local consumers. x2/5x1/56=0. Have all your study materials in one place. Forestry, agriculture, flood control, water quality . dry climates and low precipitations when excessive salts are not flushed from the earth; high evaporation rate, which adds salts to the ground surface; poor drainage or waterlogging when salts are not washed due to a lack of water transportation; irrigation with salt-rich water, which amplifies salt content in earths; removal of deep-rooted vegetation and a raised water table as a consequence; leakage from geological deposits and penetration into groundwater; sea-level rise when sea salts seep into lower lands; breezes in the coastal areas that blow salty air masses to the nearby territories; seawater submergence followed by salt evaporation; inappropriate application of fertilizers when excess nitrification accelerates soil salinization.
