Generally, sandy soil is composed of- 35% sand and less than 15% silt and clay. The mineralogy of soils is diverse. Tape grass and pondweed are the examples of _____ 12. Permeability is moderately slow to moderately rapid in the organic surface, moderately rapid in the loamy mantle, and slow or very slow in the clayey substratum.
