Salinity In Australia

Salinity is the concentration of salt that has dissolved in water. It is present in water and in soil. Salinity is a major issue in Australia as it has damaging effects which include damage to infrastructure, agricultural production loss and environmental costs. The Australian soil contains salt naturally, it is salt that has accumulated over time and there are many possibilities such as the evaporation of seas that are inland, parent rocks that are weathered. The salt on the surface is absorbed by rainfall and is carried down to the subsoil and is then stored in soil that is unsaturated where it is mobilised again by rising water and ground water, the salt is brought up when the ground water goes closer to the surface.

Rate of seed germination is decreased when there are high concentrations salt in the soil which results in prevention of essential and vital water from accessing the seed. High Osmotic potential of the soil is also a result of high salt concentration, this means that the plant must use more energy to absorb water.
Plants rely on water and nutrients in the soil to survive, plants go through a process called osmosis so that water uptake may take place. Osmosis is the movement of water through a cellular membrane, it is a type of diffusion that moves water molecules from a higher concentration of salt to a place of lower salt concentration to create a cellular environment that is stable and equal. Osmosis is vital to the stability and growth of the plant life, without the process of osmosis, other processes that are vital in the life of a plant would not occur.
This report will discuss the effects of salinity in the growth of and germination of Mung bean seeds and what the effects on mung bean seeds are whether the growth of mung bean seeds is decreased when the salt percentage of the concentration is
