Abstract

The diffusion equation for infinite cylindrical sources has been solved for the boundary conditions appropriate to timed‐release fertilizer pellets. The solution was tested against experimental results of the distortion of the image of a grind illuminated by laser light and recorded on video tape. The optical theory was examined for validity using Fermat's Principle. A computer program was developed to predict concentration as a function of time and distance with sufficient flexibility to allow for multiple sources and any other variation which can be accounted for by change of diffusion coefficient.
