WebbThe urease assay is based on the pH increase from ammonia released from urea by residual urease enzyme in SBM [12]. The urease test was conducted as following: 10 cm3 buffered urea solution (pH=7.0) was added to 0.200 g finely ground SBM (test sample), and 10 cm3 phosphate buffered solution was added to 0.200 g of the same sample (blank … Webb22 mars 2024 · When the plant absorbs a lot of nitrate ions, it gives out hydroxyl ions, and the pH increases. In general, the higher the rate of nutrient absorption, the more dramatic the change in pH. If you detect a big pH rise of 0.5 or more over 24-48 hours, it means your plants are feeding heavily.
