Using Sentinel-2 images to implement Precision Agriculture techniques in large arable fields: First results of a case study
MetadataShow full item record
This work assesses the potential of Sentinel-2A images in precision agriculture for Barley production in a case study. Two workflows are proposed: 1) images were acquired with a relatively simple methodology to follow the crop development; 2) two images around harvest time were downloaded and processed
using a more complex and accurate methodology to calculate four vegetation indices (NDVI, WDRVI, GRVI and GNDVI) to be correlated to yield with linear regression models. Yield data were acquired with a yield monitor installed in a combine harvester. Green-based vegetation indices performed slightly better. However, the highest correlation coefficient was 0.48. Better results may be achieved with earlier imagery and other vegetation indices. Sentinel-2 is a promising tool for precision agriculture in large arable crop fields.

Mapping vineyard leaf area using mobile terrestrial laser scanners: should rows be scanned on-the-go or discontinuosly sampled? Moral Martínez, Ignacio del; Rosell Polo, Joan Ramon; Company Mesa, Joaquim; Sanz Cortiella, Ricardo; Escolà i Agustí, Alexandre; Masip Vilalta, Joan; Martínez Casasnovas, José Antonio; Arnó Satorra, Jaume (Molecular Diversity Preservation International, 2016-01-19)The leaf area index (LAI) is defined as the one-side leaf area per unit ground area, and is probably the most widely used index to characterize grapevine vigor. However, LAI varies spatially within vineyard plots. Mapping ...
Spatial variability in orchards after land transformation: consequences for precision agriculture practices Uribeetxebarria Alonso de Armiño, Asier; Daniele, Elisa; Escolà i Agustí, Alexandre; Arnó Satorra, Jaume; Martínez Casasnovas, José Antonio (Elsevier, 2018)The change from traditional to a more mechanized and technical agriculture has involved, in many cases, land transformations. This has supposed alteration of landforms and soils, with significant consequences. The effects ...
Use of farmer knowledge in the delineation of potential management zones in precision agriculture: a case study in maize (Zea mays L.) Martínez Casasnovas, José Antonio; Escolà i Agustí, Alexandre; Arnó Satorra, Jaume (MDPI, 2018-06-13)One of the fields of research in precision agriculture (PA) is the delineation of potential management zones (PMZs, also known as site-specific management zones, or simply management zones). To delineate PMZs, cluster ...
