USE OF FULVICS ACIDS AND ORNAMENTAL SUNFLOWER ON REMEDIATION OF A POLLUTED SOIL WITH LEAD.

Conparative material:

AFM-Miyamonte Fulvic acid

K-tionic (fulvic acids from fossil mineral leonardite)

DPTA (synthetic chelatant agent).

The project of investigation Fulvic Acids Extracted of manure, of the Dr. Ruben Lopez Cervantes, investigative teacher of the Universidad Autonoma Agraria Antonio Narro (UAAAN) will be recognized by the State Council of Science and Technology (COECYT) in the category: Area of Natural Resources and Environment.

SOIL conditioning with Fulvic acid.

The synthetic chelating agents (EDTA, DTPA, etc.) are more expensive and difficult to obtain, that are necessary theirs economic and ecological alternatives to put the heavy metals in disposition to the plants, in this way, are in possibilities to improve contaminated soils with this pollutants materials.

With the addition of fulvic acids extracted of Miyaorganic and ornamental sunflower, a soil contaminated with lead can be remedied.
