Assessment of crop vitality through analysis of combined field and laboratory measurements of biophysical and biochemical parameters


Kneubühler, Mathias; Naef, C; Itten, Klaus I (2000). Assessment of crop vitality through analysis of combined field and laboratory measurements of biophysical and biochemical parameters. In: 2th EARsel workshop on Imaging Spectroscopy, Enschede, Netherlands, 11 July 2000 - 13 July 2000, n/a.

Abstract

Remote sensing bears the potential to provide quantitative information of agricultural crops instantaneously and of a certain regional extent. Estimates of crop growth which are used for crop yield prediction, and timing of forthcoming harvest are important in agricultural planning and policy making. For non-optimal growing conditions, estimates of crop growth may be inaccurate. Crop monitoring during the growing season by means of optical remote sensing can provide information on plant variables that describe the actual status of agricultural crops during the growing season.
In this paper, the assessment of crop vitality through analysis of both field and laboratory measurements of biophysical and biochemical parameters is investigated for wheat and barley, two main crops grown in Switzerland, be it by yield or by area. Leaf area index (LAI), fraction of absorbed photosynthetically active radiation (FAPAR), water content and chlorophyll content are defined as the main parameters defining plant vitality.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
