Microbial activities related to the soil nitrogen transformation in humid mediterranean conditions

Popis výsledku v původním jazyce

This study was carried out in the soil under oak forest (Quercus suber L.) in humid Mediterranean condition in the Sierra del Hacho situated in the Spanish province Malaga with the aim to estimate the effect of understory vegetation cover on soil microbial transformation of nitrogen (vs. bare soil). Soil samples were taken representatively twice in consecutive years (July 2008 and February 2009, representing wet and dry part of the year, respectively) from the upper soil horizons to the depth of 10 cm.To quantify net rates of N mineralization and net nitrification (and/or immobilization) we have evaluated the net changes in ammonia- and nitrate-nitrogen contents extracted from homogenized soil samples during the laboratory incubation. The significantdifferences were found out between the individual times of soil sampling (wet vs. dry part of the year) indicating the different soil conditions for mineral nitrogen immobilization, mainly sources of available soil carbon in the correspon
