faculty.une.eduFigure 3. Sorting is a measure of how even the particle size distribution. Sample A is poorly sorted while sample B is sorted. Phi is the negative log base 2 of the diameter in mm. Table 6.1 in the "Rapid Method" lab has conversions from mm or micometers to phi size.
Soil Particle Analysis Procedure
nctx-water.tamu.eduSoil pore space relates to the size of soil particles. Soils with mostly clay-size particles have greater porosity (up to 50 percent), while soils dominated by large particles such as sand and gravel have a lower porosity (closer to 35 percent). The distribution of air and water in the soil pores also relates to the soil particle size.
Classification by Distribution of Grain Sizes.
richardson.eng.ua.eduParticle‐Size Distribution Curve. The results of sieve and hydrometer analyses can be plotted to show the distribution of grain sizes. Soils with an even‐distribution of grain sizes are called “well‐graded” and soils with

8 Managing Soil pH and Crop Nutrients
extension.cropsciences.illinois.eduSampling distribution. The number of soil samples taken from a field is a compromise between what should be done (information) and what can be done (cost). The most com-mon mistake is taking too few samples to represent a field adequately. Shortcuts in sampling may produce unreliable results and lead to higher fertilizer costs, lower returns ...
