Agricultural pollution

Agricultural pollution originates from the introduction of chemical fertilizers (rich in phosphates and nitrates), pesticides (insecticides and weed killers) and manure from stables in river flows and in the soil. The discharge of chemical fertilizers in rivers, lakes and seas enhances the eutrophication phenomenon. The introduction of pesticides poses the most serious threat as these are not very biodegradable, they deposit and concentrate in river flows destroying all forms of life. A greater attention from agricultural operators could substantially reduce this form of pollution that is particularly dangerous as it can regard also aquifers. To prevent this, the contribution of nitrates must be reduced and must be favoured the use of natural manure as also must be reduced the use of pesticides introducing biological fight to avoid excessive irrigation that leaches soil and makes necessary the use of fertilizers.
