Define soil-salinity and how they cause pollution?
Soil salinity refers to the concentration of salt in the soil, which can be harmful to plant growth and productivity. Salinity can cause pollution when salts accumulate in the soil due to factors like irrigation with salt-laden water or poor drainage, leading to reduced soil fertility and ecosystem degradation.
What is the relationship between salinity and soil pH?
High salinity levels in soil can lead to increased pH levels (alkaline soil), as salts can displace other cations in the soil leading to reduced acidity. However, excessive salinity can also disrupt the soil pH buffering capacity, making the soil more susceptible to pH fluctuations. In general, salinity can indirectly influence soil pH by affecting nutrient availability and microbial activity in the soil.
How does flood irrigation lead to to soil salinity?
Flood irrigation can lead to soil salinity when excessive water is applied, causing salts to accumulate on the soil surface as the water evaporates. This accumulation of salts can then hinder plant growth and lead to long-term soil salinity issues if not managed properly.
How have people increased soil salinity?
We tend to increase soil salinity on irrigated land. Irrigation water contains some dissolved solids. When water is lost from the soil through evaporation and evapotranspiration, those salts are left behind. Over the years they can build up to the point where plants can't grow in the soil anymore, unless the farmer occasionally irrigates enough to leach the salts out of the root zone.
How might irrigation harm soil and soil organisms?
Excessive irrigation can lead to waterlogging and soil compaction, disrupting the soil structure and reducing oxygen availability for soil organisms. It can also leach away nutrients and increase soil salinity, which can harm soil microbial communities and plant growth. Over time, these effects can degrade soil health and productivity.
An increase in ocean salinity can increase what creating a current?
An increase in ocean salinity can increase density creating a convection current.

What is soil salinity or salination?
The salinity of soil refers to the amount of salt in the soil. Soil sallination is when soil becomes more salty as a result of water movement in the soil usually as a result of irrigation.

Flood irrigation can lead to soil salinity when excessive water is applied, causing salts to accumulate on the soil surface as the water evaporates. This accumulation of salts can then hinder plant growth and lead to long-term soil salinity issues if not managed properly.
Does an increase in the salinity of seawater result in an increase or decrease in density?
An increase in the salinity of seawater results in an increase in density. This is because the addition of salt (salinity) adds more mass to the water without significantly increasing its volume, leading to a denser solution. Consequently, higher salinity water is heavier than lower salinity water, impacting ocean circulation and marine life.
What will happen to salinity if the depth of the ocean increases?
There are a number of things that could happen to the salinity of an ocean if it's depth increased. The salinity would likely also increase.
What could cause the salinity of a sea to increase?
an increase in evaporation
If soil has a salinity problem what does have too much of?
If soil has a salinity problem, it means there is an excessive amount of salt present in the soil. This high concentration of salt can negatively impact plant growth and can lead to soil degradation. Improving drainage, leaching the soil with water, and adding organic matter can help manage soil salinity.

Does salinity of water increased by evaporation and the formation of sea ice?
Salinity of water increase by evaporation.
Which fruit tree growth in salinity soil?
Mutant fruit trees grow in salinity soil in Cuba.Only one percent of land based plants can grow in salinity soil. Some examples are kale, sugar beets, dates, pomegranate, arborvitae, asparagus, juniper, Russian olive and Swiss chard
