A comparison between support vector machine and water Cloud model for estimating crop leaf area index
(MDPI, 2021-04-01)The water cloud model (WCM) can be inverted to estimate leaf area index (LAI) using the intensity of backscatter from synthetic aperture radar (SAR) sensors. Published studies have demonstrated that the WCM can accurately ... -
Carbon isotopic signatures of soil organic matter correlate with leaf area index across woody biomes
(Wiley, 2014-11)Leaf area index (LAI), a measure of canopy density, is a key variable for modelling and understanding primary productivity, and also water use and energy exchange in forest ecosystems. However, LAI varies considerably with ... -
Desarrollo y evaluación de métodos prácticos no destructivos para la estimación del Área Foliar (AF) por árbol y cálculo del Índice de Área Foliar (IAF) en montes de cerezo (Prunus avium L.)
(EEA Alto Valle-Università degli studi di Bologna, 2010-11)El conocimiento del Índice de Área Foliar (IAF) de los montes de cerezo (Prunus avium L.) es una herramienta de suma utilidad para la estimación del potencial productivo. Sin embargo, su medición es muy dificultosa, por ... -
Determinación de la evapotranspiración de un cultivo de vid (Vitis vinifera cv. Cabernet Sauvignon) mediante el balance de energía y validación del coeficiente de cultivo (KC) a campo
(AATE; CPIAyE, 2021-04)Actualmente existen diversos métodos para estimar a escala local las necesidades hídricas de un cultivo agrícola, basadas en dos principios fundamentales: balance de energía y balance hídrico. El propósito del trabajo ... -
Effects of plant density in broccoli on yield and radiation use efficiency
(Elsevier, 2006)The effects of plant density on broccoli (Brassica oleracea L. var. italica Plenck) commercial characteristics are well determined. However, it is not completely clear how the broccoli plant respond to changes in plant ... -
Long-term monitoring of thinning for silvopastoral purposes in Nothofagus antarctica forests of Tierra del Fuego, Argentina
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria, España, 2018)Aim of the study: To analyse the effectiveness of thinning on tree growth, forest structure and microclimatic variables along seven years after cuttings in a secondary Nothofagus antarctica forest in Southern Patagonia. Area ... -
Medición y estimación del área foliar en plantas de yerba mate
(Universidade Regional Integrada do Alto Uruguai e das Missões (URI), 2017-05-16)En yerba mate, el producto de cosecha está compuesto por hojas y ramas finas, siendo el área foliar un parámetro importancia para evaluar el cultivo, por tal motivo, el objetivo de este estudio fue disponer de una metodología ... -
Quantifying Irrigated Winter Wheat LAI in Argentina Using Multiple Sentinel-1 Incidence Angles
(MDPI, 2022-11)Synthetic aperture radar (SAR) data provides an appealing opportunity for all-weather day or night Earth surface monitoring. The European constellation Sentinel-1 (S1) consisting of S1-A and S1-B satellites offers a suitable ... -
Relationship between biophysical parameters and synthetic indices derived from hyperspectral field data in a coastal marsh from Buenos Aires Province, Argentina
(Springer, 2016-02)Remote sensing tools allow the environmental evaluation of coastal wetlands at a landscape scale, but a deeper understanding is needed of the interactions between biophysical parameters and the electromagnetic signal. The ... -
Retrieval of Evapotranspiration from Sentinel-2: Comparison of Vegetation Indices, Semi-Empirical Models and SNAP Biophysical Processor Approach
(MDPI, 2019-10)Remote sensing evapotranspiration estimation over agricultural areas is increasingly used for irrigation management during the crop growing cycle. Different methodologies based on remote sensing have emerged for the leaf ... -
Seasonal mapping of irrigated winter wheat traits in Argentina with a hybrid retrieval workflow using sentinel-2 imagery
(MDPI, 2022-09-10)Earth observation offers an unprecedented opportunity to monitor intensively cultivated areas providing key support to assess fertilizer needs and crop water uptake. Routinely, vegetation traits mapping can help farmers ...
