Accurate estimation of rice biomass and yield estimation are not only important for rice cropping management, but also for quantitative understanding of carbon cycle in agricultural ecosystems. In this study, the fresh biomass is estimated by using broadband indices from multispectral sensor AVNIR-2 on board ALOS platform. A field campaign was carried out during June 2010 in northern part of Ir...

This study was conducted to compare forage quality of two native halophytespecies Camphorosma monspeliaca and Limonium iranicum collected from Meighansaline rangelands near Arak city in center of Iran. Edible biomass of both species wassampled on three phonological stages (vegetative growth, full flowering and seedripening). Forage quality indices such as Crude Protein (CP), Dry Matter Digestib...

Biomass can indicate plant growth status, so it is an important index for plant growth monitoring. This paper focused on the methodology of estimating the winter wheat biomass based on hyperspectral field data, including the LANDSAT TM and EOS MODIS images. In order to develop the method of retrieving the wheat biomass from remote sensed data, routine field measurements were initiated during pe...

Leaf area index (LAI) and biomass are important indicators of crop development and the availability of this information during the growing season can support farmer decision making processes. This study demonstrates the applicability of RapidEye multi-spectral data for estimation of LAI and biomass of two crop types (corn and soybean) with different canopy structure, leaf structure and photosyn...

Accurate estimates of wetland above ground biomass (AGB) have increasingly been identified as a critical component for an efficient wetland monitoring and management system. Multispectral remote sensing based indices have proven inadequate in estimating biomass especially at high canopy density. In this study we investigated the use of vegetation indices derived from field hyperspectral data to...

Herein, we report the response of indices based on phytoplankton and zooplankton and their combination to different nutrient concentrations in lakes. The study was carried out in ten lakes in northeastern Poland. Integrated samples were collected from the epilimnion during the summer of 2012-2013. Secchi disk visibility (SD), total phosphorus (TP), total nitrogen (TN), and chlorophyll a were us...
