TABLES FOR VOLUMETRIC DISPENSER WITH MECHANICAL TRANSMISSION
The dosage tables are expressed in kg/ha that the machine
will distribute, depending on the dispenser setting (see sec-
tion 6.3.1 VOLUMETRIC DISPENSER).
The tables vary depending on the specific gravity of the
product to be used. It is recommended to perform a test if
this value is not provided. Proceed as follows:
1-
Take a 1-litre container and a scale.
2-
Tare the scale with the empty container.
3-
Fill the container with the product to be used up to the
1-litre mark.
4-
Weigh the container on the scale. The value shown will be
the specific gravity.
IMPORTANT:
IF THE SCALE'S MEASURING UNIT
IS GIVEN IN GRAMS, DIVIDE THE VALUE OBTAINED
BY 1,000.
If it is not possible to perform this test, the following table lists
the most common products and their approximate specific
gravity:

9. DOSAGE TABLES
FOR PRECISION WORK, FOLLOW THE DOSAGE
PROCEDURE DESCRIBED IN SECTION 6 OF THIS
MANUAL.
THE QUANTITIES INDICATED IN THE TABLES
SHOULD BE CONSIDERED APPROXIMATE ESTI-
MATES, SINCE THE EXPECTED FLOW RATE MAY
VARY DUE TO THE POSSIBLE PRESENCE OF DIS-
INFECTANT POWDER, VARIABLE SEED SIZE, FER-
TILIZER GRANULOMETRY, DENSITY, SPECIFIC
GRAVITY, MOISTURE CONTENT, ETC.
