cultivars of blueberry and found that the maximum vegetative growth occurred at pH 4.0 and 4.5, but that there was no significant growth at pH 2.5 and 3.0. However, Schmid et al. (2009) used sulfur to acidify pine sawdust to a pH range of 3.8 and 4.2, and

ethylenediaminetetraacetic acid, pH 2.0); 5-min reaction time] ( Mehlich, 1984 ). At the end of extractions, the supernatant was filtered before being analyzed by the ICP (USEPA method 200.7). The plant samples were dried at 65 °C for 72 h and ground in a Wiley Mill to pass

, which can have secondary effects on potassium (K) uptake in plants. The objectives of this review are to 1) describe the impact of DL rate on substrate pH, 2) discuss the primary and secondary effects of DL on nutrient availability, and 3) summarize the

, pH 2.4, flow rate: 1.0 mL·min –1 , column temperature: 30 °C, detection wavelength 210 nm. Each sample was injected three times, and the corresponding organic acid or sugar content was calculated using the obtained standard curve. The average value

thawed, placed in cheesecloth, and squeezed to extract the juice from the berries. Titratable acidity and pH were measured by an 877 Titrino Plus (Metrohm AG, Herisau, Switzerland) standardized to pH 2.0, 4.0, 7.0, and 10.0 buffers. Titratable acidity was

monobasic (KH 2 PO 4 , 0.5%, w/v) at pH 2.5 with metaphosphoric acid (HPO 3 , 0.1%, w/v). The retention time of the AA peak was 2.5 min. After comparison of retention time with the AA standard, the peak was identified. The amount of total AA content in

automated titrimeter and electrode standardized to pH 2.0, 4.0, 7.0, and 10.0 buffers. Titratable acidity was determined by titrating 0.1 N sodium hydroxide to 6 g of juice diluted with 50 mL of deionized, degassed water to an endpoint of pH 8.2, with

-H refill cartridge (30 × 4.5 mm) was used for a guard column. Columns were maintained at 65 °C by a temperature control unit. Mobile phase consisted of a pH 2.28 solution of sulfuric acid and water with a resistivity of 18 M obtained from a Millipore Milli

temperature ( WSU AgWeatherNet, 2019 ). During the growing season, the average RH is 80%, while total precipitation is 39 mm per month. The soil is Skagit silt loam, a fine-silty mixed nonacid mesic Typic Fluvaquents, with 6.5 pH, 2.7% organic matter, and is

with the producers reporting research on nutrient solution formulations (mean = 3.1 ± 1.0) and nutrient solution pH (2.8 ± 1.0) being slightly to very beneficial ( Fig. 6 ). Additionally, with the majority of producers surveyed monitoring and
