WebSoil pH is measured in water using a pH meter with a combination reference glass electrode. For those soils with a pH below 6.6 a Sikora buffer solution with a pH of 7.70 ± 0.01 is added and the Sikora-pH is measured. Depression of buffer pH by the soil gives an indication of the soil’s pH buffering capacity. 3. Safety

WebLiquid water may soak into the soil in a process called infiltration. The water will move into the spaces between the solid particles of the soil, and gravitational pull will cause the water to soak deeper into the soil until it is fully absorbed. If precipitation exceeds the infiltration capacity of the soil, surface runoff will occur. WebBuffering Capacity Definition: The soil solids control or “buffer” the composition of the soil solution. Caused by dissolution of minerals, adsorption/desorption of exchangeable cations. The resistance of the soil solution to a change in composition.
