pH = 6.825 ± 0.1727 - (TIME x 0.6487 ± 0.07149) + (TIME2 x 0.1281± 0.01751)—(TIME3 x 0.00656 ± 0.001143); R2 = 0.999, MSE = 0.139. NH3-N = 9.6399 ± 1.4148 + (glycerin x 0.08728 ± 0.05779) + (glycerin x TIME x 0.146 ± 0.06041)—(TIME x 1.8245 ± 1.1698)—(glycerin x TIME2 x 0.03459 ± 0.0148) + (TIME2 x 0.2095 ± 0.2866) + (glycerin x TIME3 x 0.002012 ± 0.000966)—(TIME3 x 0.00546 ± 0.01871); R2 = 0.381, MSE = 11.75.
