No full textType of humus layer, ground vegetation, and chemical properties of the upper mineral-soil horizons were studied in a 40-years-old fertilization and liming experiment at Lutter am Barenberg in Northern Germany. In the today 109-years-old stand of Norway spruce up to 2.9 t Ca/ha, 210 kg P/ha and 150 kg N/ha had been applied. With liming and fertilization (P), raw humus and moder changed to moder and mull. In the top organic layer, pH-values (KCl) ranged from 2.6 to 2.9. In the treatment with 2.9 t Ca/ha, pH-values of the top organic layer were significantly different from those on the other plots, and in the upper 17 cm of the mineral soil the equivalent fractions of exchangeable H-ions were significantly lower. Liming and fertilization did not change the composition of the ground vegetation to such an extent, that the indicator values for nitrogen and soil moisture were different. *** DIRECT SUPPORT *** A08Z6025 0002
