    Opis:
    Specifically, it was tested whether the presence of O2 in the headspace modified the sequence and preference of electron acceptor use under hypoxic conditions after prolonged drought in arable soils. This laboratory study was conducted in order to examine the use of electron acceptors: oxygen (O2), nitrate (NO3¯) and nitrous oxide (N2O), during aerobic and anaerobic respiration (denitrification). Agricultural soils (Typic Dystrudepts) classified as sandy, silty and loamy soils from arable top soils (0-30 cm) were used in the study. The change of oxidation states of different chemical species in the soil affected the use of electron acceptors during denitrification. The use of O2, NO3¯ and net N2O use was gradual and differed greatly among the soils. Furthermore, microorganisms were shown to be able to use all three investigated electron acceptors simultaneously, but with clearly visible preferences. The rate of electron acceptor use per day differentiated the investigated soils into a few different groups. Overall, the results of this study indicated that N2O was a more preferable electron acceptor than NO3¯ when O2 was present in the headspace for the most investigated soils. Moreover, a correlation existed between the final electron acceptor use and particle-size distribution and the native organic C content (Corg). The rate of electron acceptor use per day calculated for O2, NO3¯ and N2O may provide very important information for distinguishing the preference of electron acceptor use during aerobic and nitrate respiration in agroecosystems under hypoxic conditions after prolonged drought for different kinds of electron acceptor.

    Opis:
    Nod factors produced by rhizobia are one of the most important signals involved in symbiotic associations involving legumes. A field trial was performed to assess the symbiotic activity, rhizosphere biological parameters, and plant biomass of faba bean (Vicia faba L.) treated with Nod factors. The soil was a Haplic Luvisol derived from loess. The faba bean seeds (cv. Granit) were soaked with an Nod factors solution (260 nM) or water (control) and sown. At the flowering stage, the genetic diversity of rhizobia (based on PCR-RFLP profiles and the sequencing of the 16-23S rDNA and nodD gene), nitrogenase activity (acetylene reduction assay), and nodule biomass were evaluated. Nitrogen yield and plant biomass were determined at the flowering and maturity stages. Rhizosphere soil was examined during plant growth in relation to the activities of dehydrogenase, protease, urease, and acid phosphomonoesterase. The results indicated that the application of the Nod factors improved nitrogenase activity (by 74-80%, depending on the parameter analysed) and increased the genetic diversity of rhizobia inhabiting root nodules, plant nitrogen content (by 16.8%, at maturity), and seed protein yield (by 14.6%). The rhizobial population became more heterogeneous under the influence of the Nod factors than it was for the control (12 and 7 specific genotypes, respectively). At the flowering stage, Nod factors enhanced dehydrogenase, protease, and acid phosphomonoesterase activities by 46, 36 and 9%, respectively. The results revealed the positive effect of Nod factors at reducing water deficiency effects during a growing season with a short-term rainfall deficit.

    Opis:
    The actual denitrification to N 2 O and denitri- fication capacity to N 2 O after flooding of different soil samples stored for over 25 years in air-dry conditions and fresh, air dried samples were compared in our study. Zero N 2 O release was ob- served from the stored soils but the fresh soil samples had very low actual denitrification to N 2 O. NO 3 - addition significantly increased the amount of N 2 O (denitrification capacity to N 2 O) released after flooding, which depended on the length of storage and type of soils and was much higher in stored soils. Prolonged exposure of the soils to drought conditions caused a greater decrease in the Eh value compared with the fresh soil. The total cumulative release of N 2 O from the stored and fresh soils was correlated with the reduced NO 3 - and organic C content in soils enriched with NO 3 - . Some soils showed the capability of N 2 O consumption. CO 2 release depended on the length of storage and type of soils under flooding after pro- longed drought. On average, CO 2 release was higher from the stored rather than fresh soils. The organic C content in the stored soils was generally lower than in the fresh soils, probably due to the storage effect. The cumulative CO 2 release from the stored soils was well correlated with the organic C while no correlation was observed for the fresh soil samples.
