Radioactive contamination of the biosphere is the excess of the natural level of radioactive substances in the environment. Nuclear explosions and leakage of radioactive components as a result of accidents at nuclear power plants or other enterprises can cause it. Currently, according to the International Atomic Energy Agency (IAEA), the number of operating reactors in … Read more
Soil salinity in arid and semi-arid regions is one of the most important factors limiting agricultural production Neumann (1995). Salinity levels higher than 2.0 and 2.6 dS m-1 reduce fresh yield and plant growth of lettuce De Pascale and Barbieri (1995). Lettuce is the most important and useful horticultural crop in the World. Lettuce is … Read more
