2. Sample preparation Collected soil samples are handed and prepared as follows: samples were dried and drilled. Before grinding, samples were cleaned from plant remains and other possible dirt, and pass a 2 -mm screen. Finally, samples were stored in plastic boxes in dry place until the examination according to Hungarian guideline (MSZ 20135:1999). 3. Procedure of biological and chemical soil analysis A modified periodical incubation experiment is carried out in the laboratory to determine the actual rate of N-mineralization (Stanford and Smith, 1972; Filep and Tóthné, 1980; Filep and Ferencz, 1999). We improved conditions of this modified incubation apparatus. The enlarged amount of soil (without quartz sand) is supported in a leaching glass tube. A thin glass wool pad is placed above and below the soil sample to avoid soil dispersion when the leaching solution is poured into the tube. It is leached free of mineral N and then incubated at optimum temperature (35°C) and moisture (WC=75%) for 16 weeks. 100 ml of 0.01 M CaCl2 solution is used for each N removing operation. So this way the mineralized and easily soluble organic N of soil was removed periodically. Vacuum is applied only to remove excess solution. The leachates of incubation and the chemical extractions are analysed for mineralized N (sum of nitrate and ammonium nitrogen) and organic N according to the method described by Houba et al., (1986). The different N forms were analysed by autoanalyser (SKALAR Segment Flow Analyser - CFA system). The main advantage of this method that both the 0.01 M CaCl2 soluble inorganic Nform and the UV digestable organic-N form of soil are determined simultaneously (Nagy, 2004). We used N-free nutrient solution containing 0.007 M CaSO4∗2H2O; 0.002 M MgSO4; 0.01 M Ca(H2PO4)2 and 0.015 M K2SO4 for use in replacing nutrients. The leaching process is repeated after 2., 3., 5., 7., 9., 12., and 16 weeks. The incubation can be terminated when cumulative N mineralization approaches a plateau. RESULTS AND DISCUSSIONS The incubation was applied for chosen samples 1998 and 2001 as mentioned above. The Nmin and Norg content of soil was measured along the incubation. The pH, the cumulated values of Nmin and Norg and the results of chemical extraction are shown in Table 3. 1. Results of chemical examination The pH of soil of experiment was strongly acid as earlier results (Kádár et al., 1999) and the result of control showed. Mostly the one sided N and NP, NK, NPK treatments had decreased the pH, due to the acidic effect of applied fertilizers and their long term using. Note, that only the liming treatments could hinder the further acidification and increased the pH. The amount of 0.01 M CaCl2 soluble mineral N was between 2.55 and 9.63 mg/kg 228
according to the treatments. Obtained values correspond to the soil type and ruling soil conditions. Results were pointed out that in these circumstances the mineralization processes were hindered. The amount of 0.01 M CaCl2 soluble organic N was between 4.08 and 7.25 mg/kg according to the treatments. This fraction has changed lesser than the above mentioned mineral fraction according to the treatments. The obtained results of 0.01 M CaCl2 soluble N forms can be explained the effects of applied dosage of fertilizers. The easily soluble N content of soil (Nmin + Norg) was the lowest in the control and the highest in the N2P2K2Ca2Mg2 treatment. Increasing dose of N has a negative effect on pH, slightly changed the amount of Norg and significantly increased the amount of Nmin, especially N3 treatment (Table 3).

The treatments of limed group increased the pH and the Nmin and Norg content of soil compared to the control. The amount of sum of N forms was about approximately twofold in these treatments than the control. 2. RESULTS OF INCUBATION From the cumulated data of incubation the following results can be establish: Only the treatments of limed group have increased the Nmin content of soil compared to the control (Table 3). One-sided N-treatments decreased the content of mineralized N forms of soil compared to the control during the incubation. It can be explained with the acidification effects of one-sided N fertilization which has caused unfavourable conditions for mineralization processes. Poorer mineralization conditions were caused applying treatments of NPK group as 229
