The Influence of sewage sludge from a dairy plant located in Krasnystaw on sugar beet yield was determined on the basis of an experiment on brown soil. There were six experimental treatments: without organic fertilization and liming – control, FYM with and without liming, sewage sludge with and without liming, liming without organic fertilization. Sewage sludge contained higher concentrations of N, P, Ca and Na, but lower concentration of K than FYM. The content of heavy metals in the sludge did not exceed the acceptable standards for fertilization of soil and higher plants. A significant increase of roots and leaves yield of sugar beet as a result of organic fertiliza-tion and liming was observed in the experiment.
