Crop monitoring should evaluate potential utilization problems of the harvested forage or grain, such as trace metals and PCB's if present in the waste. Frequency of sampling and parameters to be monitored will depend upon the utilization of the crop and the wastewater constituents being applied. For example, forages being harvested as hay to feed livestock should be monitored for PCB's and cadmium if PCB's and cadmium are applied in the wastewater and can accumulate on the leaf surfaces. Crop monitoring may also be used to evaluate nutrient deficiencies of minor elements or other vegetative growth problems so supplemental additions can be made to achieve optimum plant growth and wastewater nutrient uptake.
