TIPS
Potential problem/loss Cause
Simultaneous germination Residues in planting furrow, seed coulters not working
optimally, poor seed-to-soil contact, varying depth and
placement of seed, poor closing of planting furrow, incor-
rect downforce, excessive compaction next to planting
furrow, soil moisture and heat transfer from soil to seed.
Skips & doubles Topography, speed, measuring mechanism, seed size
and form. Lack of maintenance on planter, vacuum not
optimal for seed concerned, correct plate, chains must
be replaced regularly.
Spacing Plant speed, type of delivery mechanism, bumpy planter
unit, worn bushes, faulty bearings, chains which are hard
and old.
Correct plant population Soil potential, incorrect gear selection, incorrect tyre
pressure, old chains which are stretched out could fall
off.
Correct placement of fertiliser. Besides causes already mentioned - correct calibration.
and the financial impact thereof can be
determined. It also gives an indication of
where the weak link is. The latter should be
addressed in order to increase profitability.
It is no longer necessary to grope about
in the dark or to run huge risks with very
expensive inputs.
Know what your planter does per row -
clean planting furrow, correct pressure on
the soil, sufficient moisture in the planting
furrow, soil temperature, population, singu-
lation, spacing, vacuum reading, correct
fertiliser placement per row and per zone
per product, correct application of insec-
ticide per row and per zone. Why be 80%
effective if you can be 99% effective? It
has the potential to make the difference
between 6 tons and 8 tons.
