| 1. | Radionuclides migrate through either soil diffusion or transportation within the soil solution.
|
| 2. | A soil solution also experiences osmotic potential.
|
| 3. | As the concentration of solutes is increased, the osmotic potential of the soil solution is reduced.
|
| 4. | In such cases, the soil solution would severely restrict the rate of water uptake by plants.
|
| 5. | The water in the small pores of soils is not pure water; they call it soil solution.
|
| 6. | In soil solution, various plant nutrients derived from minerals and organic matters in the soil are there.
|
| 7. | The mixture of water and dissolved or suspended materials that occupy the soil pore space is called the soil solution.
|
| 8. | For the most part, nutrient ions must travel some distance in the soil solution to reach the root surface.
|
| 9. | The osmotic potential is made possible due to the presence of both inorganic and organic solutes in the soil solution.
|
| 10. | Soil colloids behave as repositories of nutrients and moisture and so act to buffer the variations of soil solution ions and moisture.
