The organic matter in the perc test borings and backhoe test pit are all low. The nitrate-nitrogen concentrations under the ball field grass all have exceptionally low nitrate-nitrogen concentrations at 1.0 ppm. This is a tribute to the School's maintenance person, Mr. Jeff Golzt, who fertilizers the grass with slow-release nitrogen fertilizers so that the grass can uptake the ammonium and nitrate fractions of the nitrogen in a timely process. The pH of the soils is alkaline at approximately 8.0 which will retard ammonium formation. The CEC ranges between 15 and 20 which would be expected given the soil texture analysis of a clay and clay loam. High CEC theoretically has a higher potential for adsorbing ammonium molecules. The clay content of the soils indicates an ample percentage of clay to promote biochemical processes, including the destruction of bacteria and viruses. Of interest, is the decrease in nitrate-nitrogen concentration of 10 ppm down to 2 ppm from the 6 ft to 10 ft depth in the backhoe test pit; an 80% decrease. Since the subject property had been recently under agricultural production, this decrease readily illustrates significant denitrification occurring from the application of nitrogen fertilizers.
