Using a new terahertz reflective-transimission design suite (TDS) system, various agricultural chemical solution were measured. A series of reflectivity spectra of agricultural chemical solution were obtained. The relation between reflection ratio and concentration of the solution was drawn. A new method for measuring the concentration of agricultural chemical solution with terahertz reflective-TDS was proposed. This method is expected to be used in the environmental pollution monitoring and manufacture quality controlling.
