Journal ArticleDOI
Evaluating ten spectral vegetation indices for identifying rust infection in individual wheat leaves
TL;DR: Ten, widely-used vegetation indices, based on mathematical combinations of narrow-band optical reflectance measurements in the visible/near infrared wavelength range were evaluated for their ability to discriminate leaves of 1 month old wheat plants infected with yellow (stripe), leaf and stem rust.
Journal ArticleDOI
Land surface phenological response to decadal climate variability across Australia using satellite remote sensing
Mark Broich,Mark Broich,Alfredo Huete,Mirela G. Tulbure,Xuanlong Ma,Qinchuan Xin,Matt Paget,Natalia Restrepo-Coupe,Kevin Davies,Rakhesh Devadas,Alex Held +10 more
TL;DR: In this paper, the authors focused on Australia, a continent with one of the most vari- able rainfall climates in the world and vast areas of dryland systems, where a detailed phenological investigation and a characterization of the relationship between phenology and climate variability are missing.
Journal ArticleDOI
A spatially explicit land surface phenology data product for science, monitoring and natural resources management applications
Mark Broich,Alfredo Huete,Matt Paget,Xuanlong Ma,Mirela G. Tulbure,Natalia Restrepo Coupe,Bradley Evans,Jason Beringer,Rakhesh Devadas,Kevin Davies,Alex Held +10 more
TL;DR: The product's algorithm and information content consisting of metrics that characterize LSP greening and browning episodes of the vegetated land surface allows tracking LSP metrics over time and thereby quantifying inter- and intraannual variability across Australia.
Journal ArticleDOI
Effect of stripe rust on the yield response of wheat to nitrogen
TL;DR: It was evident from the experiment that stripe rust caused yield loss accompanied by either no change or reduction in GPC, indicating that the total amount of N entering the grain was reduced by stripe rust, which is most likely associated with reduced uptake of N during grain filling.
Journal ArticleDOI
A Framework for Large-Area Mapping of Past and Present Cropping Activity Using Seasonal Landsat Images and Time Series Metrics
TL;DR: The complete Landsat Time Series (LTS) archive from 1987 to 2015 was used in a multi-temporal mapping approach, where spatial, spectral and temporal information were combined in multiple crop-modelling steps, supported by training data sampled across space and time for the classes Crop and No-Crop.
