Abstract: The usage of biodegradable waste as sewage sludge in a proper way for tree nurseries enable to seek for ecological, waste-less, alternative to mineral fertilization farming ways. The aim of this research is to investigate impact of sewage sludge fertilizers on Norway spruce (Picea abies) two years’ seedlings growth. Research has been done in 2013-2014 at Utena State Forest Enterprise nursery. The different fertilization rates (20, 40, 60, 80, 100 t/ha) of sewage sludge were investigated and compared with control – traditional fertilization with mineral fertilizers. The impact of sewage sludge was evaluated by seedlings biometric indicators, also dry mass of sample seedlings (medium seedlings by height and diameter). The bigger rates of sewage sludge showed almost better results in exception of seeds outlet. Sewage sludge has long lasting effect on seedlings growth and could successfully shift soil fertilization by mineral fertilizers. The obtained research results confirm the similar research carried out in 2011 in Rokiskis State Forest Enterprise nursery for first year Norway Spruce seedlings
