improve depth filter handling of O-horizon #30

Closed piersond closed 4 years ago

piersond commented 4 years ago

Do we currently have negative values for O-horizons? Or are they denoted with top and bottom depth of zero? How can we modify the sliders to improve handling of these layers?

This is not done consistently. Some times there's a horizon character string that help (when depth_top = 0). I've also put a threshold of lyr_soc < 20%C or bd_samp > 0.6 to screen out what are likely organic horizons. Once again, no perfect solutions...

Changed depth slider min and max values to -3 to 300. Also changed sliders to take a value range. We'll have to see how we like using the ranges. It's slightly more complicated, but allows for more exact selection of soil layers.
