Soil Factors Part 1
Check Appropriate Square
A.
Texture
---------------
SURFACE
feels gritty but contains enough silt
and clay to make moist soil hold
together. If squeezed when moist,
a mold can be formed which can
be carefully handled without breaking.
It forms no ribbon or very
poor ribbon
--------------- ---------------
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 be
tend to break or the ribbon
will bend downward.
