Remote Sensing of Plant Stress As an Indicator of Chemical Concentration of Biosolid Amended Surfacesoils.

The accumulation of heavy metals in the biosolid amended soils and the risk of their uptake into different
plant parts is a topic of great concern.This study examines theaccumulation of several heavy metals and
nutrients in plants grown on biosolid applied soils and the use of remotesensing to monitor the
metal uptake and plant stress. Field and green house studies were conducted with soybeans grown on
soils applied with biosolids at varying rates.The plant growth wasmonitored using LandsatTM imagery
and hand held spectroradiometer in field and green house studies,respectively. Soil and plant samples
were collected and then analyzed for several elemental concentrations.This study suggests the use of remote sensing to
monitor soybean stress patterns and thus indirectly assess soil chemical characteristics.
