PROCEDURE TO ELIMINATE PHYTOSANITARY PRODUCTS PRESENT IN SOILS
ES2538626
The present invention relates to a method that uses the activity of earthworms to accelerate the elimination of phytosanitary products present in the soil. The procedure applies particularly to organophosphorus and pyrethroid compounds, and exploits the secretion of carboxylesterase enzymes in the digestive tract of earthworms, in addition to other ecological characteristics of earthworms. The inoculation of this species in soils contaminated with phytosanitary residues facilitates the degradation of these substances as a result of the action of the earthworm as a "dynamic bioreactor", reducing or eliminating the limitations of other biotechnological systems to achieve this purpose, such as inoculation of microorganisms or the stimulation of microbial communities in the soil.

This invention aims to offer an environmental service in the agricultural field marked by the low cost of its application and its reduced or null environmental impact. <p> The addition of endogeic earthworms to soil treated with pesticides (or even before undertaking a pesticide treatment) increases the degradation of these substances. <p> The invention focuses on the degradation of two groups of pesticides commonly and currently used in agriculture, organophosphorus pesticides and pyrethroids.
