A composition for increasing selenium in vegetables consists essentially of a watery solution of selenium salts, with a selenium content ranging between 0,5 and 200 grams of selenium per cubic meter of solution. Said solution includes moreover: solvents ranging from 0,005% to 25% of the liquid phase, to facilitate the selenium absorption by the vegetable; surface-active agents in concentration variable from 0,001% to 0,25% of the liquid phase, to facilitate the vegetable wettability and for reducing the surface tension thereof; biopolymer with a weight/volume concentration ranging between 0,001% and 0,20%, for regulating the composition viscosity and the selenium transfer to said vegetables; molybdenum salts in a weight/volume concentration varying from 0,20 to 250 grams per cubic meter of solution. |
