Summary[edit]
DescriptionWorld Soil pH.svg |
English: I retrieved the soil pH maps from [1]. In GIMP 2.4.3 I used the "Select by Color Tool" (threshold 15.0) to create pH-specific maps. Note that the original maps do not indicate actual pH values in the pH scale. For soils with acidic pH, I included the colors indicated by the leftmost 14 bars in the pH scale, ranging from red to pink. For soils with basic pH, I included the colors indicated by the rightmost 6 bars on the pH scale, ranging from light blue to blue. For soils with neutral pH, I included the remainder of the bars on the pH scale, which included very light pink, white, and very light blue. I then referenced these pH-specific maps to draw regions of differing soil pH on File:BlankMap-World6.svg. Because the original maps from Atlas of the Biosphere and File:BlankMap-World6.svg use different map projections, some ambiguity was introduced into this map. Thus it can only be taken to represent basic trends in soil pH, not precise boundaries.
