A number of individual samples are usually collected in this manner and these are then typically bulked up together into a larger sample which is then sent to the lab for analysis…

Soil Acidity (pH)

Soil acidity, or its pH value, refers to the relative proportion of hydrogen (H+) ions and hydroxyl (OH-) ions in solution in the soil water. A low pH indicates a high concentration of H+ ions, and greater acidity, and conversely, a high pH indicates a low concentration of H+ ions, and lower acidity (higher alkalinity). A pH meter measures acidity on a logarithmic scale…
