A diffusive gradients in thin-films (DGT) methodology for in situ measurement of imazamox and imazapyr herbicide residues Open
Imidazolinones (IMIs) are a group of commonly used chiral herbicides. However, because of their persistence and mobility, IMI herbicides pose a toxicity risk to non-target aquatic organisms and sensitive crop varieties. Conventional grab s…

Plant responses to nitrate and ammonium availability in Australian soils as measured by diffusive gradients in thin-films (DGT) and KCl extraction Open
Determining soil nitrogen (N) availability is essential in agriculture to minimise over-application, maximise growers’ returns and reduce potential environmental consequences. The present study assesses soil mineral N (nitrate-N and ammoni…

Identifying soil and climate drivers of soil water conditions favourable for deep phosphorus placement for wheat in Australia using spatial modelling Open
Phosphorus (P) fertiliser is often placed shallow, near the seed, and plant-available P tends to be concentrated in the topsoil (0–5 cm), because of its relatively immobile nature and the dominance of no-till cropping systems. Concern abou…

Using mid-infrared spectroscopy as a tool to monitor responses of acidic soil properties to liming: case study from a dryland agricultural soil trial site in South Australia Open
Soil acidification is an issue for agriculture that requires effective management, typically in the form of lime (calcium carbonate, CaCO 3 ), application. Mid infrared (MIR) spectroscopy methods offer an alternative to conventional labora…

Evaluation of the diffusive gradients in thin-films (DGT) technique for measuring nitrate and ammonium in soil Open
Environmental context Nitrate (NO3−) and ammonium (NH4+) are the most important soil nitrogen forms for plant growth. However, conventional extraction techniques may introduce artefacts affecting the measurement of plant-available N concen…

Combined application of nitrogen and phosphorus to enhance nitrogen use efficiency and close the wheat yield gap on varying soils in semi‐arid conditions Open
A primary driver of the wheat yield gap in Australia and globally is the supply of nitrogen (N) and options to increase N use efficiency (NUE) are fundamental to closure of the yield gap. Co‐application of N with phosphorus (P) is suggeste…

Novel diffusive gradients in thin films technique to assess labile sulfate in soil Open
A novel diffusive gradients in thin films (DGT) technique for sampling labile soil sulfate was developed, based on a strong basic anion exchange resin (Amberlite IRA-400) for sulfate immobilization on the binding gel. For reducing the sulf…
