Salting the earth, or sowing with salt, is the ritual of spreading salt on the sites of cities razed by conquerors. [1] [2] It originated as a curse on re-inhabitation in the ancient Near East and became a well-established folkloric motif in the Middle Ages. [3] The best-known example is the salting of Shechem as narrated in the Biblical Book ...
Detrimental effects on plant growth and yield; Damage to infrastructure (roads, bricks, corrosion of pipes and cables) Reduction of water quality for users, sedimentation problems, increased leaching of metals, [6] especially copper, cadmium, manganese and zinc. Soil erosion ultimately, when crops are too strongly affected by the amounts of salts.
where Ci is the salt concentration of the irrigation water, Cc is the salt concentration of the capillary rise, equal to the salt concentration of the upper part of the groundwater body, Fc is the fraction of the total evaporation transpired by plants, Ce is the salt concentration of the water taken up by the plant roots, Cp is the salt ...
Nitrogen is a common element in nature and an essential plant nutrient. Approximately 78% of Earth's atmosphere is nitrogen (N 2). The strong bond between the atoms of N 2 makes this gas quite inert and not directly usable by plants and animals. As nitrogen naturally cycles through the air, water and soil it undergoes various chemical and ...
An ancient practice in time of war was salting the earth: scattering salt around in a defeated city to prevent plant growth. The Bible tells the story of King Abimelech who was ordered by God to do this at Shechem , [ 18 ] and various texts claim that the Roman general Scipio Aemilianus Africanus ploughed over and sowed the city of Carthage ...
Establishing salt-tolerant plants can improve salt discharge rates and improve soil health. Improvements undertaken at a catchment scale bring many benefits, not the least of which is providing for increased agricultural and associated regional productivity – using water for production that otherwise would contribute to an environmental problem.
I understand that a detailed discussion on the effectiveness of salting the earth to prevent crop growth belongs in a separate article on soil salinity, but there's a difference between saying "they're different issues deserving separate articles" and taking the stance that they are completely unrelated and irrelevant to each other, which ...
Consequences include corrosion damage, reduced plant growth, erosion due to loss of plant cover and soil structure, and water quality problems due to sedimentation. Salination occurs due to a combination of natural and human-caused processes. Arid conditions favour salt accumulation. This is especially apparent when soil parent material is saline.
