Abstract:
A sandy clay loam which often showed priming effects in a differently fertilized (control, 120 kg N/ha, 240 kg N/ha) long-term field experiment, was aerobicly incubated (25-degrees-C) and analysed for chemical and microbial parameters. The total nitrogen and C(org) contents in the 240 kg N/ha treatment were markedly lower than in the unfertilized as well as in the 120 kg N/ha treatment. Long-term fertilization with 240 kg N/ha increased the dehydrogenase activity by about 34% in comparison to the control and about 54% to the 120 kg N/ha variant and enhanced the population of amino acid ammonifying and proteolytic bacteria. After analogous fertilization in model trials, positive as well as negative priming effects were shown. Thereby no linear dependence occurred in relation to the amount of nitrogen added. The effects on biological criteria were similar both under laboratory conditions as well as in long-term field experiments. The total nitrogen and C(org) contents of humus fractions partly showed differences in dependence on fertilization.
