Autor: G. Guardia, D. Abalos, S. García-Marco, M. Quemada, M. Alonso-Ayuso, L. M. Cárdenas, E. R. Dixon, A. Vallejo

Publikováno v: Biogeosciences, Vol 13, Iss 18, Pp 5245-5257 (2016)

Agronomical and environmental benefits are associated with replacing winter fallow by cover crops (CCs). Yet, the effect of this practice on nitrous oxide (N2O) emissions remains poorly understood. In this context, a field experiment was carried out

Long-term management changes topsoil and subsoil organic carbon and nitrogen dynamics in a temperate agricultural system

Autor: A S, Gregory, J A J, Dungait, C W, Watts, R, Bol, E R, Dixon, R P, White, A P, Whitmore

Publikováno v: European Journal of Soil Science

Summary Soil organic carbon (SOC) and nitrogen (N) contents are controlled partly by plant inputs that can be manipulated in agricultural systems. Although SOC and N pools occur mainly in the topsoil (upper 0.30 m), there are often substantial pools

High rates of nitrogen cycling in volcanic soils from Chilean grasslands

Autor: E R, Dixon, L, Cardenas, M, Alfaro, F, Salazar, D J, Hatch

Publikováno v: Rapid communications in mass spectrometry : RCM. 25(11)

There are over one million hectares of pasture in Chile, and 80% and 50% of the country's milk and meat comes from 72% of this area, situated in the lake region of southern Chile. The soils are volcanic and a major characteristic is that they have ve

Evidence for the production of NO and N2O in two contrasting subsoils following the addition of synthetic cattle urine

Autor: E R, Dixon, R J, Laughlin, C J, Watson, D J, Hatch

Publikováno v: Rapid communications in mass spectrometry : RCM. 24(5)

Nitrogenous materials can be transferred out of the topsoil, either vertically to a greater depth, or in lateral pathways to surface waters, and they may also become transformed, with the potential of generating environmentally active agents. We meas

Measurement at the field scale of soil delta13C and delta15N under improved grassland

Autor: E R, Dixon, M S A, Blackwell, M S, Dhanoa, Z, Berryman, N, de la Fuente Martinez, D, Junquera, A, Martinez, P J, Murray, H F, Kemp, W, Meier-Augenstein, A, Duffy, R, Bol

Publikováno v: Rapid communications in mass spectrometry : RCM. 24(5)

Variations in natural abundance of carbon (C) and nitrogen (N) stable isotopes are widely used as tools for many aspects of scientific research. By examining variations in the ratios of heavy to light stable isotopes, information can be obtained as t

The inter-relation of some mechanical properties with molecular weight and crystallinity in poly(ethylene terephthalate)

Autor: J. B. Jackson, E. R. Dixon

Publikováno v: Journal of Materials Science. 3:464-470

Some mechanical properties of poly(ethylene terephthalate) were determined as a function of molecular weight, temperature and crystallinity. The effect of talc, a nucleating agent, on mechanical properties was also considered.

Spectral distribution of Australian daylight

Autor: E. R. Dixon

Publikováno v: Journal of the Optical Society of America. 68:437

Measurements of the spectral distribution of Australian daylight falling on a horizontal plane over the wavelength range 280–2800 nm have been made at two locations in southeastern Australia, one set of measurements in an urban environment and the
