Terms
and Definitions
General:
These terms and definitions should be used only as
guidelines. Individual interpretations may vary
from State to State. Only those items included in
the National Crop Progress release are discussed.
Definitions:
Days Suitable for Fieldwork: A
'suitable' day is one where weather and field conditions
allowed producers to work in fields a major portion
of that day.
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 the current
time of year. Some supplemental feeding is required
to maintain livestock condition.
-
Fair - Less than normal crop condition.
Yield loss is a possibility but the extent is
unknown. Pastures are providing generally adequate
feed 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 experiencing 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 phenological stage when 50 percent or more of
the plants in that acre are in or beyond that stage.
Planted: A crop is considered
planted when the seeds are placed in the ground.
For transplanted crops, the planting period refers
to the time of setting the plants in the field.
Harvested: A crop is considered
harvested when the crop is cut, threshed, or otherwise
gathered from the field.
