The pH of a natural soil depends on the mineral composition of the parent material of the soil, and the weathering reactions undergone by that parent material. In warm, humid environments, soil acidification occurs over time as the products of weathering are leached by water moving laterally or downwards through the soil. In dry climates, however, soil weathering and leaching are less intense and soil pH is often neutral or alkaline. WebTo illustrate the effects of soil texture and organic matter on pH adjustment, your lab instructor added various rates of dolomitic limestone to a sandy soil, a clay soil, and an organic soil. The rates of limestone ranged from zero to 10 tons/acre. After several months, the following pH values were measured: Table 14.4. WebSoil pH indicates the degree of soil acidity or alkalinity, and is reported using a scale ranging from zero to 14, with pH 7.0 being the neutral point. Soils with pH values below 7.0 are acid and above 7.0 are alkaline. china hobby line lipo batteries
