Nitrogen rhizodeposition of young wheat plants under elevated CO2 and drought stress
No full textThe objective of this study was to determine the effect of drought stress and elevated CO2 concentrations around the shoots on N rhizodeposition of young wheat plants. In a pot experiment, the plant N pool was labeled through (NH3)-N-15 application to shoots at nontoxic NH3 concentrations, and the impact of low water supply (40% field capacity), elevated CO2 (720 mu mol mol(-1) CO2), and the combination of both factors on the N-15 distribution was studied. Total N-15 rhizodeposition ranged from 5 to 11% of the total N-15 recovered in the plant/soil system. Elevated CO2 concentration as well as drought stress increased the belowground transport of N and increased the relative portion of N rhizodeposition on total N-15 in the plant/soil system. However, while the increased N rhizodeposition with elevated CO2 was the result of increased total belowground N transport, drought stress additionally increased the portion of N-15 found in rhizodeposition vs roots. Elevated CO2 intensified the effect of drought stress. The percentage of water soluble N-15 in the N-15 rhizodeposition was very low under all treatments, and it was significantly decreased by the drought-stressed treatments
Coordination Equilibrium in an Ln(III) Macrocyclic Chelate Modulated by a Reversible Interaction with a Weakly Donor Substituent
No full textThe introduction of a squaric acid moiety at the secondary nitrogen center of DO3A [DO3A = 1,4,7-tris(carboxymethyl)-1,4,7,10-tetraazacyclododecane] yields the DO3ASQ ligand endowed with a potential octadenticity towards Ln(III) ions. On the basis of 17O NMR investigations on [Gd(DO3ASQ)(H2O)], 13C NMR observations on [Lu(DO3ASQ)(H2O)] and UV spectra of [Eu(DO3ASQ)(H2O)], it is suggested that [Ln(DO3ASQ)(H2O)] complexes are present in solution as a mixture of two isomers differing in the coordination number of the Ln(III) ion, being 8 and 9, respectively. Only in the latter isomer is the squaric moiety coordinated to the Ln(III) ion. Interestingly, the two isomers display different exchange rates of the coordinated water molecule

No full textThe origin of soil organic C, dissolved organic C and respiration in a long-term maize experiment in Halle, germany, determined by C-13 natural abundance
No full textFor a quantitative analysis of SOC dynamics it is necessary to trace the origins of the soil organic compounds and the pathways of their transformations. We used the C-13 isotope to determine the incorporation of maize residues into the soil organic carbon (SOC), to trace the origin of the dissolved organic carbon (DOC), and to quantify the fraction of the maize C in the soil respiration. The maize-derived SOC was quantified in soil samples collected to a depth of 65 cm from two plots, one 'continuous maize' and the other 'continuous rye' (reference site) from the long-term field experiment 'Ewiger Roggen' in Halle. This field trial was established in 1878 and was partly changed to a continuous maize cropping system in 1961. Production rates and delta(13)C of DOC and CO2 were determined for the Ap horizon in incubation experiments with undisturbed soil columns. After 37 years of continuous maize cropping, 15% of the total SOC in the topsoil originated from maize C. The fraction of the maize-derived C below the ploughed horizon was only 5 to 3%. The total amount of maize C stored in the profile was 9080 kg ha(-1) which was equal to about 31% of the estimated total C input via maize residues (roots and stubble). Total leaching of DOC during the incubation period of 16 weeks was 1.1 g m(-2) and one third of the DOC derived from maize C. The specific DOC production rate from the maize-derived SOC was 2.5 times higher than that from the older humus formed by Cg plants. The total CO2-C emission for 16 weeks was 18 g m(-)2. Fifty-eight percent of the soil respiration originated from maize C. The specific CO2 formation from maize-derived SOC was 8 times higher than that from the older SOC formed by C-3 plants. The ratio of DOC production to CO2-C production was three times smaller for the young, maize-derived SC than for the older humus formed by C-3 plants
