Abstract: The study determined the influence of microirrigation (microjet sprinkling and drip irrigation) and organic fertilization (compost prepared on the base of sewage sludge) on growing vigour and a degree of mycorrhiza of one-year old Scotch pine (Pinus sylvestris L.) seedlings produced with the use of zoo-melioration. Two-year (20032004) field experiments were carried out in forest nursery at Biale Blota, Forest Inspectorate of Bydgoszcz. Investigations were conduc-ted on a brown rusty soil formed from loose sandy soil. The first order factor was irrigation used in three treatments: without irrigation (control), drip irrigation, microjet sprinkling. The second order factor was fertilization, used in two variants: mineral fertilization (standard applied in forest nurseries), organic fertilization (compost). Irrigation significantly increased the height and diameter of Scotch pine seedlings. There were no significant differences in the characters of seedling growth between two irrigation systems. Fertilization of Scotch pine seedlings with the compost from sewage sludge with peat admixture significantly increased the height of seedlings. An interaction of irrigation and organic fertilization in effect on Scotch pine seedling height and diameter was observed. Pine seedlings grown on plots fertilized with compost under irrigation conditions were characterized by larger height and diameter. Experimental factors differentiated the mycorrhiza number in pine seedlings. Majority of irrigated sites, especially in case of microjet sprinkling and organic fertilization joint effect, was characterized by increased number of Oribatida. Colonies of Oribatida on studied area were dominated by Oribatula tibialis. Ob-tained results indicate that microirrigation may be considered as an alternative for sprinkler irrigation commonly used until now in forest nurseries.
