Feldspar Distinctions, Characteristics Identification
Aug 10, 2019· Alkali feldspar (also called potassium feldspar or Kfeldspar) has a color range from white to brickred, and it's typically opaque. Many rocks have both feldspars, like granite. Cases like that are helpful for learning to tell the feldspars apart. The differences can be subtle and confusing.

What Are the Causes of High Potassium in Soil? | Garden Guides
Weathering of feldspar and mica in the soil causes the breakdown of potassium from fixed to nonexchangeable to exchangeable (plant available) forms. Mica releases potassium more easily than feldspar. Although leaching of potassium is slow or minimal, regions where the climate is humid and wet tend to have lower amounts of plant available potassium.
