* Look through Ch. 10 Agriculture and Soils, Ch. 11 Forestry Applications

Forestry  A. Use of Elements of Interpretation in species identification.  B. Distinguishing between conifers and deciduous trees On B&W IR film, conifers are dark deciduous are light  A. Spring   Hard to distinguish crops at early growth phases.  B. Midsummer   Height of growing season; this is an optimal time for crop identification.  C. Late summer/Autumn   Field patterns are distinct;  harvesting is at different times/stages for different crops.  D. Winter   Tones are generally dull and drab. Crop phases are different for different areas, it is important for the photo interpreter to become familiar with the crop calendar and cultural practices of the region they are interpreting. Soils    A. Bare soil     1.  Lighter tones are generally indicative of one or more of the following:      a)  low soil moisture  b)  low organic content      c)   finer textured soils  d)  higher topography     2. Darker tones are generally indicative of one or more of the following:      a)  high soil moisture  b)  high organic content      c)   coarse textured soils  d)  area lower topographically   B. Soil moisture is most easily distinguished using IR film.   IV. Drainage Patterns     a)  dendritic  b)  trellis  c)  radial     d)  rectangular e)  centripetal f)  deranged    In general, the coarser the stream pattern, the more resistant is the bedrock.
