The phrase "absolute soil" is correct and usable in written English.
It can be used in contexts related to geology, agriculture, or environmental science to refer to soil that is considered pure or unaltered.
Example: "The researchers collected samples of absolute soil to analyze its composition and nutrient levels."
Alternatives: "pure soil" or "uncontaminated soil".
As MRD was considered, time stability of absolute soil moisture primarily characterized time-invariant patterns.
However, as VRD was used, the time stability of absolute soil moisture characterized only a small part of time-invariant or -variant pattern.
Here we characterized soil moisture spatiotemporal variability in the Yuanzegou catchment (0.58 km2) on the Loess Plateau of China, considering both absolute soil moisture and temporal anomalies.
Furthermore, the upward-convex relationship between spatial variance and spatial means of absolute soil moisture was mainly characterized by the covariance of temporal mean and temporal anomalies.
Results indicate substantial differences in the effects of the three tillage patterns in terms of absolute soil erosion-accumulation rates and the spatial distribution of areas of soil loss and deposition.
Time stability of absolute soil moisture and its components were analyzed by using both the "accuracy" metric mean relative difference (MRD) and the "precision" metric variance of relative difference (VRD).
Temperature data from 2004 to 2011 were used to calculate annual values of absolute minimum soil temperature, annual daily mean soil temperature, absolute maximum soil temperature, temperature sums (>5 °C), growing degree days and the length of the growing season across the years sampled.
The absolute minimal soil temperature for green bean seeds is 48 degrees Fahrenheit (9 degrees Celsius).
In some cases it may be useful to be able to quantify relative changes in erosion, without trying to estimate absolute values of soil loss.
Experimental mass or activity balance studies have shown that absolute losses from soils of key radionuclides such as 137Cs by processes such as cropping and leaching are small: Radioactive decay can probably dictate the rate at which agricultural systems become decontaminated.
The absolute area of each soil system differed between rivers, but sediment supplied typically did not result in great soil texture variation per landform.
