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 of one-year old verrucose birch (Betula verrucosa Ehrh.) 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 conducted on a brown podzolic 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: mine-ral fertilization (standard applied in forest nurseries), organic fertilization (compost). Studied irrigation systems significantly increased the height and diameter of verrucose birch seedlings. The seedlings grown under microjet sprink-ling con-ditions were significantly higher than those under drip irrigation. Fertilization of the seedlings with compost significantly increased the height and diameter of seedlings. Significant interaction of irrigation and organic fertilization was obser-ved. Irrigated verrucose birch seedlings grown on plots fertilized with compost were characterized by larger height and diameter. Use of irrigation, especially with organic fertilization positively influenced the dimensions of seedlings and number of saprophage species of Oribatida. Colonies of Oribatida on control sites were dominated by Tectocepheus velatus and on irrigated sites by of Oribatula tibialis. Positive results of applied amelioration measures in the experiment sug-gest a possibility of their wider use in production of forest nurseries what is especially important in wiew of afforestation of ineffective agricultural areas.
