The investigation conducted as a pot and field experiment was with perennial plant species (grapevine), where the immobilization effects of heavy metals (Cr, Ni) were investigated. Poor substrate was supplied with N and P different rates of fertilizers, while K was constant (100 kg/ha). Phosphorus nutrition was focused on the immobilization effects on deposol Cr and Ni availability, by using increasing doses of MAP fertilizer (5.000, 15.000, 30.000 and 45.000 kg/ha). Treatment with zeolite, which has similar immobilization effect as P, was also applied with MAP fertilizer treatments. The analysis of plant material from pot experiment pointed out a significant adsorption of nickel in some organs with higher doses of MAP fertilizer, ...

In addition, this study tested a potential risk of the accumulation of heavy metals during the commercial production of basil on agricultural soil. Mineral composition of basil genotypes was found to be in association with its genetic potential, where some of them can be used in human nutrition as an additional source of several minerals, particularly micronutrients (Fe, Mn, Zn), which generally improve human immune system. Iron-rich basil genotypes were identified in this experiment, like Compact (3576.0 mg/kg), with Lattuga (1585.6 mg/kg) and Blue spice (1167.9 mg/kg) genotypes, containing more than 1000 mg/kg of Fe in herbal part on dry basil (d.m.).

During a thre- year experiment (1994-1996), potassium fertilizer was added in a dose of 0 kg K2O/ha, 50 kg K2O/ha, 100 kg K2O/ha, 150 K2O/ha respectively. After the determination of soil potassium content (1870-1920 mg K2O/100 g), its available form was monitored by using two different extraction methods (AL method and 1N ammonium-acetate extraction). The amount of extracted available K was not significant between the used methods, while the effect of fertilization was visible only at 150 kg/ha potassium rate during the first year in soil layers (30-60 cm, 60-90 cm). Also, another examined soil K fraction (fixed K+) was not affected by K fertilizer application.

The soil we used had a certain crop rotation (wheat-corn) and had been fertilized according to a certain system for 30 years. In the experiment, quantities of nitrogen fertilizers were gradually increased after which samples were taken from O to 30 cm depths in order to establish plant and soil parameters for assessing the applied methods. Two experiments were made: one in the field and one in a controlled environment. On grounds of the established correlation interdependence between the methods applied (the total and easily hydrolyzed nitrogen) and the plant and soil parameters, in both field and pots, one can conclude that the methods of total and easily hydrolyzed nitrogen, from the standpoint of nitrogen availability in soil, are reliable. In the method of total nitrogen assessment, one should rely on the parameters regarding plants and soil in the field. In the method of easily hydrolyzed nit...

We have chosen those experiment variants in which quantities of nitrogen fertilizers were gradually increased. The soil samples taken from 0 cm to 30 cm depth were used to determine biological indexes of nitrogen availability (aerobic and anaerobic incubation). The same samples were also used for pot experiments with oat. Plant and soil parameters obtained in controlled conditions were used for determination of biological indexes reliability in measuring the soil nitrogen availability. On the grounds of correlation analysis, it can be concluded that biological index of nitrogen availability achieved by the anaerobic incubation (without substraction of the initial content of available nitrogen) of the investigated brown forest soil is the reliable indicator of soil nitrogen availability. That is not the case with the aero...

An incubation study to test the soil potential and the validity of analytical methods was conducted at 3, 8, 15, and 20 °C for up to 128 days on soils from western and south-eastern Norway. Soils with the highest pH showed the highest mineralization. The mineralization increased with increasing temperature and time, but start-up N reduced mineralization. The mineralization cannot be estimated from standard soil chemical parameters because the different C/N ratio indicates organic material of different origin and quality. The increase in NO3-N started very quickly and ranged from 17 to 182% and 12 to 64% after 8 days at 3 °C and 20 °C, respectively. There was no correlation between total N in the soil and the amount of mineralized N. On average, the mineralization increased by 5–7% for a change of 1 °C in the interval from 8 to 15 °C in the soil. The chemical extraction method using heated KCl correla...

The total contents of Ni and Pb were 152 and 109 mg kg(-1), respectively. Geochemical fractionation of Ni, combined with mineralogical analysis, confirmed its geogenic origin in the soil. Potentially mobile fractions were the dominating binding forms of Pb; thus, indicating anthropogenic sources as prevailing. Risk assessment indicated a low risk of Ni and Pb transfer from soil to other environmental constituents. However, the results imply that geogenic metals might pose higher environmental risk than those from anthropogenic origin, in dependence of their total concentrations and contents in the specific solid-phase fractions. Flooding of the soil was simulated in an automated biogeochemical microcosm system, which a...

Researches were made on experiment variants where the increasing dosage of nitrogen fertilizer was applied. The aim of the research was to establish which plant and soil parameters (pots and/or field) might be considered reliable to evaluate values of applied chemical methods (hot water method and easily hydrolyzing nitrogen), being methods used to evaluate potentially mineralized nitrogen in soil. We also wanted to establish the most favorable time to evaluate the values of applied methods (March, July and October). On the basis of established correlation dependences, the plant and soil parameters, either from pots or fields should be used to evaluate the reliability of the hot water method and the reliability of mentioned methods can be estimated in March, July and October. As for the evaluation of easily hydrolyzing nitrogen, we can use bo...

The potential ammonification in soil was obtained by arginine method. The following properties of soil were determined: pH value organic C, available NH4-N and mobile-Al. The pH value in vertisol was 3.75-4.07; mobile-Al was 0.67-4.90 mg/100g; % organic C 1.38-1.46 and the content of available nitrogen was 4.4-11.2 ppm. The amount of released NH4-N by arginine ammonification in this soil type was very low [(-0.12)-0.27mg/g-1h-1]. Correlation coefficients between released NH4-N from arginine and soil pH were (-0.96*), mobile Al - (-0.99**), applied fertilizer doses - (-0.95*). In brown forest soil the amount of released NH4-N by arginine ammonification was greater than in vertisol, ranging from 3.16 to 7.11mg/g-1h-1. Correlation coefficients between soil properties and released NH4-N from arginine were not sta...

Experiment variants with an increasing dose of nitrogen fertilizer were chosen for this research. Two experiments have been performed: experiment in pots supplied with ammonium nitrate labeled with a stable isotope 15N (11.8%) and experiment in the field. The aim of the research was to establish which plant and soil parameters group (obtained in the controlled conditions and/or in the field) could be considered as reliable for evaluation of aerobic and anaerobic incubation and of the best time for estimation of potentially mineralized nitrogen in soil. According to the determined correlative dependence, it could be concluded that reliability of aerobic incubation should be estimated in October by plant and soil parameters from field, anaerobic incubation should be estimated in early spring (March) by plant and soil parameters, from controlled condition...

Furthermore, in order to ensure successful fertilization, there should be satisfactory stigma receptivity, rapid pollen tube growth along the style, as well as adequate ovule longevity. This manuscript presents the study of the effective pollination period (EPP) of four ?Oblacinska? sour cherry clones (II/2, III/9, XI/3 and XIII/1) that differs in pollen germination, fruit set and yields. In order to estimate EPP, pollination was conducted in six different stages of flower development: balloon stage, 2 d before anthesis (-2), at anthesis (0), and 2, 4, 6 and 8 d after anth?sis (DAA). The initial (IFS) and final fruit set (FFS) were recorded under the field conditions. Alongside with this, the rate of pollen tubes growth in the style was observed with fluorescent microscopy. The experimental design was completely randomized, a two-factorial analysis of variance was c...
