I made a particle size analysis on 150 soil samples using the hydrometer and sieve method. For each sample, I have a table with particle diameter (d) and percent passing (%P), which indicates the sample's amount consisting of particles smaller than diameter X : Data table
I can make a particle size curve from this table : Particle size curve
From this curve, I can get the percent passing at 50µm and 2µm to determine the soil clay (<2µm), silt (between 2µm and 50µm), and sand (>50µm) content.
It takes a lot of time to do that with 150 samples, so I want a code in R to get soil clay, silt, and sand content from the data in the table (d and %P).
I read about the soil texture wizard in R, but it doesn't seem like it would help me solve my problem.
Thanks!
