IMPACT ON SOIL
Chemical fertilizers are frequently used in agriculture for increasing agricultural outputs. Incorrect handling can cause soil pollution and damage to surface waters. The paper provides a series of chemical fertilizers examples used frequently in Romania. Furthermore the paper is showing an analysis on their impact on soil and water. A series of determinations were made for revealing their presence and their provenance. In this regard the paper is proposing to carry out a data base for revealing information about: identification, implementation and evaluation of risk assessment on soil caused by certain pollutants (heavy metals, nitrides).
