Soil Factors Part 1
Check Appropriate Square
A.
Texture
---------------
SURFACE SOIL
is slightly smooth or velvety feel when
moist. When moistened soil is
squeezed out between thumb and
forefinger, it will form a poor ribbon
with dull surface
---------------
SUBSOIL

Soils usually break into
clods or lumps when
dry. When the moist
soil is squeezed between
the thumb and forefinger
it will form a short well-formed
ribbon with a shiny surface
which will tend to break
or the ribbon will bend downward.
