The influence of the sewage sludge from a dairy Krasnystaw (Poland) on sugarbeet yield was determined on the basis of large-area experiment on brown soil formed from silt. There were six experimental treatments: without fertilization - control, FYM with and without liming, sewage sludge with and without liming, liming without organic fertilization.
