1. A method of tracking the intentional depositing of vehicle-transported sewage sludge on plots of land comprising the steps of:
- (a) storing in the memory of a computer boundary information identifying the respective plot boundaries of a plurality of plots of land;
(b) using said boundary information in the computer for determining a plurality of polygons defined by the superposition of said plot boundaries so that each of said plots includes at least one of said polygons and, so that, if one of said plots overlaps another of said plots, then said one of said plots includes at least two of said polygons;
(c) determining in said computer the area of each of said polygons using said boundary information;
(d) storing in said computer memory quantity data representative of the quantity of sewage sludge deposited on said plots and analysis data representative of selected constituents including at least one of metals and nutrients of the sewage sludge deposited on said plots; and
(e) determining in said computer the cumulative quantity per unit area of said constituents deposited on said polygons using said polygon area, quantity data and analysis data thereby tracking sewage sludge deposited on the plots.

Abstract
A biosolids tracking system monitors the quantity and quality of biosolids deposited on a plot of land. Global positioning system technology is used to determine the land coordinates of the boundary of the plot of land for accurate area calculation in order to determine the loading per unit area of biosolids including metals deposited on the plot. The system includes the ability to display superposed topographic and digitized photographic imagery of the plot with textual annotation.
