Summary:

In environments with a high salinity are halophytes, which are exposed not only to the stress of salinity but also the stress associated with a deficiency of oxygen The gradual build-up of the problem in areas used for agriculture, affects the orientation of research, aiming at the selection of crops with high tolerance to saline soils, including irrigated.The aim, carried out in 2008-2009 experience, was the choice of plant species for phytoremediation of soils irrigated and fertilized for many years.The conducted experiments show that, of the growth and development of plants, to assess their suitability reclamation of saline soils, most of the nitrogen is indicated and greening index, to a lesser extent the height of the plants.There was an interaction between fertilization and the formation of species of fresh and dry weight of plants.This was mostly fresh and dry weight of aboveground and in the case of roots, only their fresh weight.Given the increase in salinity of the ground and most studied plants showed resistance to salinity white mustard, corn and least resistant species was yellow lupine. This is evidenced by lower salinity, the concentration of calcium, potassium and phosphorus in the soil subjected to many years of irrigation and fertilization with nitrogen and potassium in comparison to the control objects (be fertilization).Conducted experience has shown that the most appropriate species for phytoremediation of soils with many irrigation and fertilization could be, white mustard and sweet corn, to a lesser extent, Italian ryegrass. This has not been a positive impact in the case of yellow lupine.
