    The effect of strategic nitrogen application and defoliation systems on the productivity of a perennial ryegrass/white clover sward (1987)

    Notes: The productivity of a mixed sward comprising perennial ryegrass cv. Fantoom and white clover cv. Aran was measured under eight defoliation management systems and two fertilizer N rates (0 and 75 kg ha-1) applied in spring. The defoliations involved a basic six-harvest simulated grazing system together with the interposition of silage cuts once or twice at varying times during the growing season; evaluation was made over three harvest years, 1983-85.Mean annual production of total herbage DM over the three years was 8.351 tha-1 without N and 9.49 tha-1 with 75 kg N ha-1, a mean response of 15.2 kg DM per kg applied N. The responses for individual treatments occurred mainly at the first cuts, whether for simulated grazing (a mean of 12 9 kg DM) or for silage (a mean of 259 kg DM); however, this influence of spring N was not sustained at other cuts over the season. Mean annual white clover DM production was 4.19 t ha-1 with no N and 3.32 t ha-1 with 75 kg ha-1 N, but the reduction due to N was not significant in any year. The mean amount of clover stolon DM present post harvest over all management systems was 1.33 t ha-1 with no N and 1.03 t ha-1 with 75 kg ha-1 N.Mean annual DM production of total herbage from the six-harvest system was 8.11 t ha-1 Compared with 8 88 t ha-1 (a 9% increase) from the systems with one silage cut and 9.241 ha-1 (a 14% increase) from the systems with two silage cuts. Corresponding white clover DM production was 4.02, 3 87 and 3 53 t ha-1, respectively, and mean stolon DM amounts post harvest, 1 12,1.15 and 1-23 t ha-1, respectively.It is concluded that grass/white clover swards are suitable for management systems which involve cutting for conservation. Spring N application did not greatly reduce white clover production in this experiment where white clover was at higher levels than are likely in farming practice and the swards were not grazed. More knowledge of spring N rates, and indeed of N application rates generally, would be advantageous in future assessment of silage cutting systems.

    Precision X-ray optics for fundamental interactions in atomic physics, resolving discrepancies in the X-ray regime (1999)

    Topics: Electrical Engineering, Measurement and Control Technology , Physics
    Notes: Abstract Reliable knowledge of the complex X-ray form factor (Re(f) and f″) is required for many fields including crystallography, medical diagnosis and XAFS studies. However, there are discrepancies between theory and theory, experiment and experiment and theory and experiment of 10% and more, over central X-ray energies. Discrepancies exist for most elements, despite claimed experimental accuracies of 1%. This paper summarises the current variation between experimental and theoretical results, and outlines key issues for obtaining experimental accuracies of 1% in critical wavelength ranges for selected elements to address these issues. This paper critically surveys available experimental data for attenuation coefficients and suggests a procedure for obtaining significantly higher accuracy measurements in the future.

    The quantitative variability and monosaccharide composition of sediment carbohydrates associated with intertidal diatom assemblages (1999)

    Notes: Abstract The extracellular secretions of epipelic diatoms (Bacillariophyceae) are an important source of carbohydrates on intertidal sediments. For analytical purposes, sediment carbohydrates have been operationally separated into colloidal and bulk fractions that are often assumed to be similar in their chemical properties. However, there has been little investigation into the nature of the two fractions. In this study, carbohydrate fractions were sampled in situ, isolated, purified and biochemically characterised using gas chromatography-mass spectrometry (GC-MS). Both carbohydrate fractions were found to contain similar sugars although in different proportions. Glucose represented more than 80% of the monosaccharides identified in the colloidal carbohydrate fraction while only 37% of monosaccharides present in the bulk carbohydrate fraction. Colloidal carbohydrate concentrations showed short-term variability and were correlated with diatom biomass (as chlorophyll a) suggesting the colloidal fraction is labile and may be of recent origin, perhaps representing diatom activity. Concentrations of the bulk carbohydrate fraction did not show significant short-term variation and was therefore more refractory. This combination of biochemical and field data suggested that the bulk and colloidal carbohydrate fractions were chemically and physically different. These findings have relevance to studies of estuarine carbon cycling.
