Practical test for distribution of seed and fertilizer
The most appropriate way to assess the amount of seed and fertilizer to be distributed
is on the actual ground where planting will be carried out, as follows:
• Whenever possible, use the same tractor and operator for planting.
• The Correct calibration of the planter's tires is important. Maintain the same pressure
in all
(32 psi)
.
• Check the distance for the test. Follow the example in the fertilizer table: 50 linear
meters.
• Fill at least half the planter's hoppers and moves a few meters so the distribution
units can be filled completely before entering into the marked area.
• Place containers at the fertilizer outlets (use preferably plastic bags).
• Move the tractor along the marked area, using the same speed that you will work
throughout the planting.
• Recommended speeds:
5 to 5.5 km/h to plant corn/sunflower;
6 to 6.5 km/h to plant bean/sorghum/ acid-delinted cotton;
7 km/h to plant soybean.
• Now just weigh the fertilizer in the containers and compare it with the 2nd line of the
tables on the previous page (grams in 50 meters per row).
• Remove the cotton waste from the seed transporting units, collect the seeds and
count them. This way, you can also check if they are not being damaged.
• If necessary, run the test again changing the adjustments.
• After achieving the desired amounts and still at the terrain, move the tractor at the
same speed, but now letting the fertilizer and the seed reach the soil to better check
the uniformity of the distribution.
Adjustments and operations
Data in the previous tables (seed and fertilizer) may vary due to
many factors. Therefore, we request that you carefully notice the
following item.
IMPORTANT
• The variation of the working speed affects the uniformity of seed
distribution.
• Every time you change the batch of seeds or the fertilizer
manufacturer, it is necessary to assess again.
• It is important to assess all the settings again after the first day of
work.
