The application of water footprint accounting is mostly done at large scales, but the estimation of crop- and region-specific water footprints for up-scaling is dependent on accurate and representative in-field measurements of evapotranspiration (ET)

Effective and efficient methods are needed to map agricultural subsurface drainage systems. Visible-color (VIS-C),multispectral (MS), and thermal infrared (TIR) imagery obtained by unmanned aerial vehicles (UAVs) mayprovide a means for determining dr

Poor management of irrigation water and nitrogen (N) fertiliser in ryegrass cropping systems reduces forage yield, and quality, N-use efficiency, and potentially leads to atmospheric and water pollution. The objective of this study was to calibrate a

Nitrogen is often poorly managed in irrigated agro-ecosystems. Accumulation and leaching of N can occur due to excessive fertiliser N, high soil inorganic N carryover between seasons, rapid mineralisation in spring and poor irrigation scheduling. Thi
