Timeliness
of field work
Timeliness of field work means
more to successful management of
farm land and machinery resources
than anv other factor. For example, if
the soil is worked too soon or too Tate
in the spring, crop losses may y occur:
1) working clay land when it is too
wet can mean a yield loss of as much
as 25 per cent; 2) spring grain yields
decrease 75 kg/ha per day (1.5 bu/ac
per day) if planting is delayed after
May 1; and 3) corn yields decrease
nearly 60 kg/ha per day (1.0 bu/ac
per day) if planting is delayed after
May 10.
Accurate weather information to
make both day to day and long-term
planning decisions is required for
field work timeliness. Daily weather
forecasts are used for day to day deci-
sions. But there are no dependable
yearly or even seasonal weather
forecasts to assist with Tong -term
planning decisions such as machinery
selection, crop rotation, and
organization. Farmers have to de-
pend on past experiences for this in-
formation and often such recollec-
tions may be misleading. The recent
development of computerized farm -
planning aids has demonstrated the
usefulness of accurate agronomic and
climatic information for farm
budgeting.
Field work timeliness centers upon
two major factors, how much time is
available for field work and how
much field work the machinery can
do. The first factor we have very little
or no control over. Adjusting
machinery size is not necessarily the
only or the best means of controlling
' timeliness. Hiring extra help at
critical times such as at planting time
can be just as economical. With extra
help, equipment can be operated
more hours per day to cover addi-
tional ground. There are many con-
siderations that influence timeliness,
and the important thing is to plan
work to achieve optimum economic
farm production.
