In the spring and autumn 2005 during the application of livestock manure in Slovenia 74 samples of cattle slurry, 30 samples of cattle solid manure, 19 samples of cattle liquid manure in 13 samples of pig slurry were collected. The chemical composition of gathered livestock manure samples was very variable. Cattle slurry contained 8,4 % dry matter (3,0-13,2 %) in 6,7 % organic matter (1,7-11,5 %), 0,9 kg MgO (0,3-3,1 kg), 1,6 kg P2O5 (0,5-2,7 kg), 4,0 kg K2O (1,5-8,9 kg), 3,6 kg N (1,0-5,6 kg), 1,6 kg NH4 -N (0,4-3,2 kg), 3,8 g Cu (0,8-14,3 g) and 17,7 g Zn (3,9-53,8 g) in a cubic meter. Cattle solid manure contained 18,6 % dry matter (11,7-27,5 %), 14,6 % organic matter (9,8-22,4 %), 1,8 kg MgO (0,7-3,7 kg), 3,0 kg P2O5 (1,3-6,1 kg), 5,1 kg K2O (1,7-11,8 kg), 4,7 kg N (2,7-8,5 kg), 0,8 kg NH4 -N (0,1-2,0 kg), 4,7 g Cu (2,1-8,8 g) and 24,4 g Zn (8,7-64,3 g) in a ton. Cattle liquid manure contained 2,0 % dry matter (0,2-6,3 %), 1,1 % organic matter (0,1-4,3 %), 0,4 kg MgO (0,01-2,0 kg), 0,3 kg P2O5 (0,02-2,0 kg), 3,9 kg K2O (0,6-9,3 kg), 1,5 kg N (0,2-3,6 kg), 1,2 kg NH4 -N (0,1-3,3 kg), 0,6 kg Cu (0,03-2,6 g) and 2,1 g Zn (0,1-10,9 g) in a cubic meter. Pig slurry contained 4,8 % dry matter (1,2-16,4 %), 3,5 % organic matter (0,7-11,9 %), 0,9 kg MgO (0,1-2,9 kg), 3,0 kg P2O5 (0,6-10,6 kg), 2,9 kg K2O (1,7-6,6 kg), 5,0 kg N (2,6-13,1 kg), 3,2 kg NH4 -N (1,3-5,5 kg), 10,5 g Cu (1,0-27,7 g) and 39,0 g Zn (6,9-89,0 g) in a cubic meter. The content of P, Zn and Cu in the dry matter of cattle slurry was in positive correlation with the application quantity of mineral fertilizers and the quantity of concentrates and mineral-vitamin supplements in the diet.
