CARTAYA-RUBIO, Omar E. et al. Effects of the application an oligogalacturonide mixture on a polluted soil cultivated with tomato seedlings. cultrop [online]. 2016, vol.37, n.4, pp.160-167. ISSN 0258-5936.  http://dx.doi.org/10.13140/RG.2.2.20663.52642.

It was carried out a rehearsal with a contaminated soil by copper (Cu), in order to evaluate the risk associated to the application of technical of phytorremediation with chelates (Ogal mixture) in these cases. They thought about different situations: normal soil without addition of Ogal (control), polluted soil without addition of Ogal and polluted soil and Ogal concentrations of 20, 40, 60 80 and 100 kg ha^-1 respectively. The pseudototal copper content was measured in the soil, pH and organic matter of the soil and longitude (air and underground) of the tomato plants. The results show that the lenght of the plants that grew in a polluted soil without the product application suffered a significant descent with relationship to the control; however, to those that was applied the product, they diminished their lenght, but not so markedly as the previous ones. On the other hand, the cation of the system experiented an increase of their mobility with the presence of the Ogal mixture, being bigger their phytoextration when dose of 60 kg is applied
