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.
