- after irrigation salt from the water remain in the soils
- in some regions rivers carry salted waters from the mountains
- a local contamination from an industrial activity
- contamination from sea water or other bodies of salt water
Brackish soils are soils that contain a mixture of saltwater and freshwater, with higher salinity levels than freshwater but lower salinity levels than seawater. These soils can be found in coastal areas, estuaries, and marshlands, and are typically a result of tidal influence and the mixing of saltwater and freshwater. Brackish soils can have specific challenges for plant growth and agriculture due to the unique salinity levels.
Iron oxides account for the red tint to soil .
Major causes for soil depletion include intensive agricultural practices, such as over-farming without proper crop rotation, excessive use of chemical fertilizers and pesticides, and deforestation leading to erosion. These practices can strip the soil of essential nutrients, decrease its ability to hold water, and degrade its overall quality for plant growth.
Dilatancy of soil refers to an increase in volume or expansion that occurs when soil particles are sheared or subjected to stress. This phenomenon causes a soil to become less dense and increases its permeability. Dilatancy is commonly observed in granular materials like sand during shear deformation.
Gravity is the force that pulls rock and soil down a slope. As materials become loosened, gravity causes them to move downhill due to the force of gravity acting upon them.
when brackish water(seawater mixed with freshwater) comes into contact with soil.
Deforestation cause l;and pollution because when we cut don the trees, the soil will become loose and soil erosion will take place.
The twice-daily event that causes water levels around Jamestown to rise and makes wells and fresh water streams become brackish is the tide. The tidal cycle brings in seawater, increasing the salinity of the water in wells and freshwater streams located in the vicinity of Jamestown.
Soil can become acidic due to natural processes such as weathering of minerals, leaching of basic cations, and decomposition of organic matter. Human activities like the use of fertilizers, acid rain, and mining can also contribute to soil acidity.

Mangrove trees have become specialized to survive in the extreme conditions of estuaries. Two key adaptations they have are the ability to survive in waterlogged and anoxic (no oxygen) soil, and the ability to tolerate brackish waters.
Fields become muddy when there is an excessive amount of water or rain that saturates the soil, making it unable to absorb any more water. This causes the top layer of soil to become waterlogged and turn into mud. Heavy foot traffic or livestock can further churn up the soil, exacerbating the muddy conditions.
Soil becomes hydrophobic when it is exposed to certain conditions, such as high temperatures, prolonged drought, or the presence of certain organic compounds. These conditions can cause the soil particles to repel water, making it difficult for water to penetrate and be absorbed by the soil.
Brackish Boy was created in 1993.
The water in this part of the swamp seems to be more brackish. The waters of Loch Ness are very brackish.

Tropical and brackish are not mutually exclusive. Tropical means warm, and brackish means somewhat salty. Many brackish fish ARE tropical, and many tropical fish are brackish. You can keep tropical brackish fish with other tropical brackish fish, if they have the same temperment and will not harm or eat eachother. You can keep some brackish fish with some freshwater tropicals, and similarly you can keep some brackish fish with some marine tropicals. There are no wide open set of principles for brackish fish compatability beyond those that I have just illustrated.
