clayloam

<p>Data obtained with a 152H hydrometer in accordance with ASTM D422-63 (2007).</p>

data

Small toolbox for data analyses in environmental chemistry and
ecotoxicology. Provides, for example, calibration() to calculate calibration
curves and corresponding limits of detection (LODs) and  limits of
quantification (LOQs) according to German DIN 32645 (2008). texture() makes
it easy to estimate soil particle size distributions from hydrometer
measurements (ASTM D422-63, 2007).
