Top and Sub-soil
Moisture
：
top-soil defined as
the top 6 inches
?
Very
short
-
Soil
moisture
supplies
are
significantly
less
than
what
is
required
for
normal
plant
development.
Growth
has
been
stopped
or
nearly
so
and
plants
are
showing
visible
signs
of
moisture
stress.
Under
these
conditions,
plants
will
quickly
suffer
irreparable
damage.
?
Short
-
Soil
dry.
Seed
germination
and
/or
normal
growth
and
development
would
be
curtailed.
?
Adequate
-
Soil
moist.
Seed
germination
and
or/
crop
growth
and
development
would
be
normal
or unhindered.
?
Surplus
- Soil wet. Fields
may be muddy and will generally be unable to
absorb additional
moisture. Young
developing crops may be yellowing from excess.
General Crop Condition
?
Very
poor
- Extreme degree of loss to yield
potential, complete or near crop failure. Pastures
provide very little or no feed
considering the time of year. Supplemental feeding
is required
to maintain livestock
condition.
?
Poor
- Heavy degree of loss
to yield potential which can be caused by excess
soil moisture,
drought, disease, etc.
Pastures are providing only marginal feed for
current time of year.
Some supplement
feeding is required to maintain livestock
condition.
?
Fair
- Less than normal crop
condition. Yield loss is a possible but the extent
is unknown.
Pastures are providing
generally adequate but still less than normal for
the time of year.
?
Good
- Yield prospects are
normal. Moisture levels are adequate and disease,
insect damage,
and weed pressures are
minor. Pastures are providing adequate feed
supplies for the current
time of year.
?
Excellent
- Yield prospects
are above normal. Crops are expecting little or no
stress. Disease,
insect damage, and
weed pressures are insignificant. Pastures are
supplying feed in excess of
what is
normally expected at the current time of year.
Crop Progress Percents
Progress percents relate to acres and
should indicate the progress of field activities
or crop
development. Generally, an acre
should be considered in or beyond a phonological
stage when 50
percents or more of the
plants in that acre are in or beyond that stage.
?
Planted
-
A
crop
is
considered
planted
when
the
seeds
are
planted
in
the
ground.
For
transplanted crops, the planting period
refers to the time of setting the plants in the
field.
?
Harvest
- A crop is
considered harvest when the crop is cut, threshed,
or otherwise gathered
from the field.
?
Normal
- The averaged rate
based on the records of immediate past 5 years.
Wheat Growth Stages
?
Emerged
- As soon as the
plants are visible.
（出芽）
?
Tilling
- A plant develops
branches as known
（分蘖）
grown from the nodes of the
stem,
just
below
or
at
the
soil
surface.
The
lowest
node
at
which
a
strong
tiller
is
produced
is
called the
?
Jointing
- Stem extension
growth of stem between
nodes(joints).
（节间伸张）
?
Boot
stage
- The sage of development of
florets in the head, just before
heading.
（孕穂期）
?
Headed
- The head is
presented, visible, and fully
emerged.
（出穂）
?
Milky
stage
- The stage of filling starch in
the kernel, and the dough is soft and milky. Also
