Have studied the value of the nitrogen metabolism in the adaptation of the red clover plants (T. pretense L.) to the conditions of the oil polluted soil. It was shown that the oil pollution of the soil have caused the significant accumulation of the non-protein nitrogen-containing composites in the roots and shoots of T. pretense L., the protein content in roots didnít change, but decreased in the shoots of the plants. Adding the non-nitrogen fertilizers to the polluted soil have assisted the decrease of the accumulation of the low molecular nitrogen composites induced by the soil pollution with oil in the organs of clover plants.


Keywords: nitrogen, T. pretense L., the oil polluted soil, fertilizers
