Soil pH measures acidity, which affects nutrient uptake by plants. The most common soil laboratory measurement of pH is the 1:1 water method. A crushed soil sample is mixed with an equal amount of water, and a measurement is made of the suspension. For each soil layer, this attribute is actually recorded as three separate values in the database. A low value and a high value indicate the range of this attribute for the soil component. A "representative" value indicates the expected value of this attribute for the component. For this soil property, only the representative value is used. A weighted average aggregation method was used to aggregate soil components within a 0-30 cm depth range. The dataset was derived...
