The process by which plants can pump salts out of their roots is called "ion exclusion."
Ion exclusion is a mechanism by which plants are able to prevent the uptake of unwanted ions, such as sodium (Na+) and chloride (Cl-), while still allowing the uptake of essential ions, such as potassium (K+) and calcium (Ca2+).
This process involves specialized cells in the root called "transfer cells," which have a high concentration of transport proteins in their cell membranes. These transport proteins actively transport ions across the membrane, creating an electrochemical gradient that allows the exclusion of unwanted ions.
In addition, the roots of some plants have a specialized layer called the "endodermis," which acts as a barrier to the movement of ions from the root to the shoot. This layer also contains transport proteins that selectively allow the passage of essential ions while excluding unwanted ones.
Overall, the ion exclusion process is an important adaptation that allows plants to survive in soils with high salt concentrations

Salts are absorbed by the roots.
Plants absorb mineral salts from the soil thanks to their roots.
- absorbing salts from soil by the roots - for some plants fixing nitrogen with the help of bacteria
osmosis
many things but mostly makes a balanced soil so plants can absorb nutrients. Roots when feeding the plants try to get rid of salts and with bad pH these salts will build up around the roots (looks like a snot ball...eww) and keep roots from absorbing...etc..
Many plants require roots. Basically, the roots are required to absorb water & mineral salts. The roots, being long & narrow will absorb water and mineral salts as they grow between the soil particles rich in these raw materials. This is why, the roots of a balsam plant are important.
Nitrate or Ammonium salts. These are called Fixed Nitrogen.
During photosynthesis , sugar is made by the plants. The plant absorbs minerals salts form water or from the soil by its roots. These salts provide importants elaments to the plants e.g nitrogen , calcium , iron .
in hydroponics,the roots of plants are immersed in solutions containing dissolved mineral salts.
Magnesium is a very important microelement for animals and plants. Essential for plants growth and for the process of photosynthesis, production of chlorophyll.
Plants absorb salts from soils and waters.
