Abstract: | Summary The effect of fertilizer nitrogen on the available amount of soil nitrogen was investigated in a greenhouse experiment. To 9 different soils, 0, 50, 100 and 200 kg N/ha were applied, resp., as (N15H4)2SO4 with an atom excess N-15 of 1%.No priming effect could be found for any of the treatments. The available amount of soil N, expressed as AN value, was not affected by rate of N-fertilizer application. |
