6.
Then perform the following calculations:-
Measured amount of fertiliser initially loaded in hopper (A)
10kg
Deduct any remaining fertiliser (E)
4kg
Balance Used
6kg
Multiply width of spread (D)
8 metres
By the metres travelled (C)
x 200 metres
= 1,600sq. Metres
Divide 10,000 by the answer (1,600)
10,000 / 1,600 = 6.30
Multiply the sum (6.30) by the test quantity used (B)
6kg (B) x 6.30 = 37.80kg
The figure achieved is the sowing rate per hectare at the constant speed
selected for the test.
7.
Due to the variations of seeds and fertiliser types, it is recommended the test be carried out for
each product being used
8.
Record all results to ensure accurate speed rates for future reference and minimal wastage.
