Estimating leaf chlorophyll contents of shade grown tea using hyperspectral data

Multivariate statistical methods for estimating grassland leaf area index and chlorophyll content using hyperspectral measurements

Grassland habitat covers about one-quarter of the Earth’s land surface, providing significant contribution to the world’s total agricultural production, plant biodiversity, and carbon sequestration. The advent of hyperspectral remote sensing and the future launch of planned spaceborne hyperspectral missions will open up new possibilities over conventional multispectral RS to better quantify gra...

Estimation of Leaf Area Index and Chlorophyll for a Mediterranean Grassland Using Hyperspectral Data

The study shows that leaf area index (LAI) and canopy chlorophyll content can be mapped in a heterogeneous Mediterranean grassland from canopy spectral reflectance measurements. Canopy spectral measurements were made in the field using a GER 3700 spectroradiometer, along with concomitant in situ measurements of LAI and chlorophyll content. We tested the utility of univariate techniques, involvi...

Selection of Optimum Reflectance Ratios for Estimating Leaf Nitrogen and Chlorophyll Concentrations of Field-Grown Cotton

often result in immoderate growth, increased input costs, and potential adverse environmental impacts, esLeaf N and chlorophyll (Chl) concentrations of cotton (Gossypium pecially water quality (Jaynes et al., 2001). Therefore, hirsutum L.) are important indicators of plant N status. Laboratory one of the goals of farm managers is to accurately detect determinations of plant tissue N are time co...

Estimating Corn Leaf Chlorophyll Concentration from Leaf and Canopy Reflectance

Farmers must balance the competing goals of supplying contributions of background reflectance, while spectral vegetation indices that combined reflectances of near-infrared adequate N for their crops while minimizing N losses to the environment. To characterize the spatial variability of N and other visible bands (MCARI and NIR/Green) were responsive to both leaf chlorophyll concentrations and ...
