The buffer in acidic range is a mixture of a weak acid and salt of conjugate base of the weak acid. And a buffer in a basic region is a mixture of weak base and salt of conjugate acid of weak base. Buffers are substances that minimize changes in concentrations of ions i.e. either H+ ions or OH- ions.

Highly accurate pH4 solution. Acidity level: pH4. Shake the bottle before use. Always pour a small amount into another container to test pH, and do not place your pH probe directly into the bottle. This will avoid contamination of the Buffer 4 in the bottle and will maintain its accuracy.

The two main effects the pH level has on plant growth is related to the availability of plant nutrients or the soil concentration of plant-toxic minerals. Equally affecting growth when there are low pH values, calcium, phosphorus and magnesium are less available to the plant.
