Levels of plant nutrients in the growing media at the end of the experiments were reasonably good. Yet, the analyses did not reflect the differences in fertilizer rates used in the experiments (Table 2). The pH of the media remained in the appropriate range with the expected decrease in pH at the higher rates of Peter’s and Omega. Electrical conductivity in all treatments was somewhat higher than optimal levels. The level of nitrate nitrogen was surprising low for all treatments. Phosphorus levels were lowest in the fish emulsion, yet no problems would be expected at these levels. Potassium was somewhat low for all treatments. The highest fertilizer rates for Peter’s and Omega yielded the lowest potassium levels for an unknown reason. Most calcium and magnesium is supplied by the irrigation water, not the fertilizer. Calcium levels were fine in all treatments, magnesium levels were increased somewhat by the Omega organic fertilizer.
